HI-SPEED FANS (do not blow directly into open filter). Should we re-tune for this “air leak?” Absolutely not. This means that the best answer to this question is to get both an e-tune and a dyno-tune. and other data from the OEM computer in real time. MEASUREMENTS WILL BE DIFFERENT WHEN CORRECTING FOR OTHER “STANDARDS”. 35. It comes with a chip burner, chips ($25/each), emulation laptop capability, instructions, and tech support. Also, the car then stalls, bogs, sputters, power is down and there’s black smoke out the exhaust – and now you want to blame Kenne Bell because we won’t re-calibrate it and the dyno can’t fix it. 8. The tire pressure in the slicks had dropped from 35-15 psi. By using the accurate diagnostics we obtain, our technicians can tune your performance vehicle or sports car accordingly. However, if your goal is to make a particular product that doesn’t make power look good, just keep adding other products until something makes HP and the claim “one needs the other to perform best.”. Also, Dyno runs are not the same are 1/4 mile runs. If you want to go at this … On the face of it this should be a simple choice, but even here there are options and not all dynos are created equal. It’s easy. … Dyno tuning, basically, puts your car on a giant treadmill. To eliminate this variable, a sensor in back of the filter in the inlet tract is necessary as that’s the true air temp the engine “sees.”. In all fairness to dyno operators, many aren’t even aware that their sensors are providing faulty readings. Treat yourself good, treat your car better. When we have a customer who doesn’t accept our explanation, we recommend that he check his car on another dyno just to prove the readings are erroneous. aus oder wählen Sie 'Einstellungen verwalten', um weitere Informationen zu erhalten und eine Auswahl zu treffen. 5. DYNO CALIBRATION – If the air temp varies by 40° between two runs, for whatever reason, and the dyno is not calibrated for the specific change, the HP will change approximately 4%, or about 1% for every 10°. An e-tune will average the values out in real world conditions, taking the numbers from the datalogs you provide for the conditions AT the track. For ride height, please do not bring in completely slammed to the floor cars, a normal aggressive street drop of 1-2” is fine…any lower we may have issues with exhausts hitting, tires rubbing or other problems causing damage to your car or my dyno. It allows YOU to tune YOUR car on the dyno or at the track using elapsed times between known rpm points. Accurate dyno testing a single product is difficult enough. Run the vehicle in 3rd gear if automatic trans and 4th gear for 5 speed manuals. Testing can last as long as several days trying to maximize performance by trying different parts and dyno tune … Dyno tuning offers high-quality tune-ups for your engine to boost its overall performance. Again, 10° temp variation is around 1% in power. Conventional Bolt Ons” “Real vs. As you might expect the most common use for a chassis dynamometer or rolling road is for tuning or remapping and power runs, we can also confirm that vehicle performance is as it should be, we can also use the rolling road for diagnostic purposes, allowing us to identify all manner of running issues, the kind of things that would normally require empty roads and at … tuning parameters that vary engine HP. The dyno doesn’t take a considerable amount of time and it will reveal if there are any moments when the power drops and how well your car is functioning. Try this example. Again, low temps mean richer mixtures and high temps will allow leaner mixtures. To further alter the amount of water in the bucket, do a little on-off action on that trigger nozzle. We are very familiar with all the GM, Ford, Chrysler etc. Ready for car-tuning 101? Their slow response to a dyno run isn’t even close. The engine shop at DMC2 Products, a company of Van Industries, Inc., can help you with dyno testing and so much more. I’ll just say this. Be sure to document yourself thoroughly before investing time and money into anything. HOOD CLOSED WITH OPEN FILTER – This one should be self explanatory. the car has run at least 3 minutes from a cold start prior to making the first run so it does not run in the wrong “cold fuel mode table” – air/fuel readings will indicate rich in this mode). An accurate comparison test requires both the ACT and ECT readings be identical on both runs. At 9.1, the overly rich mixture can damage expensive cats and sensors, foul plugs and wash cylinder walls. All Kenne Bell dyno tests are run that way – unless, of course, you want a dyno run with less power. A “locked” torque converter will typically improve 1/4 mile times by .25 sec and 2.5 mph. Our indepth guide covers car engine tuning for all popular types of engine. Disregard these spikes. Dyno tuning allows us to give your vehicle a tune-up of unparalleled quality, providing you with the smoothest, most economical performance possible from your vehicle. Here at Dyno Tune Mitchell, we are the car servicing and repair specialists for virtually all makes and models. It doesn't matter what make and model car you have or are looking at tuning, this course will be applicable. The IAT sensor may also adjust air fuel ratio. Install any alternate injectors, map sensor and chip that you will be running to get to the dyno. Kenne Bell uses the SAE calibration. So that you can make an educated decision about what is best for your car, I’ve written this article to guide you through the options so you can sort fact from fiction. Same dyno type, the AFR ratio varies from 15.1 to 11.0 – BUT THE HP IS THE SAME? Another example” A 4:10 gear rear end is 93% efficient vs. 91% for a 4:30. using the ECM or Horiba, please, no “tailpipe sniffer” air/fuel readings. DRAIN OUT ANY FUEL WITH AN OCTANE OF LESS THAN 100. MAKE SURE THE TANK IS OVER 1/4 FULL WITH PURE 91 OCTANE OR BETTER. Most of the time, the days or weeks before your scheduled time on the dyno approaches are utter … Only today, the vehicles are far more complicated and difficult to tune because of an ever increasing number of variables. The tuner must 1. advance the timing and/or 2. lean out the AF ratio. How does one know when this is happening on the dyno? Lose any underhood exposed “hot air” filter – where no one else can find it. The solution is to always dyno test with adequate fuel octane and THE SAME IGNITION TIMING. IT FEEDS HOT AIR TO YOUR ENGINE INSTEAD OF THE COLD AIR. Fortunately, the websites are of some help in identifying these people. We have documented cases where 2 dynos across the street from each other varied a full point – yet the HP was identical. We purchased the very first Dynojet rack dyno in the West in 1996. Fuel octane, by itself, will not affect dyno HP i.e. I’ve had my car for over ten years and have made a bunch of mods (TD05, AEM EMS, FMIC, Ross pistons, etc). 6. We’ve measured up to 200° underhood temps on a 100° day. 100HP will get you approx. Blocks under the gas pedal, riding the brakes, three quarter throttle runs, skewed dyno calibrations, tweaked sensors etc. Again, 1° of ignition timing is 4HP. 13. DETERMINING HP FROM 1/4 MILE TIMES – The Dynojet and the Superflow inertia dynos are extremely accurate in HP Hydroflow. We hope it has helped. A dependable .5 ratio variation isn’t that serious a problem because it can be deducted if you want the best milage, power etc. Also, as we always recommend, NEVER, EVER run in SHOOTOUT mode unless running straight 100 octane fuel or better or engine damage will occur. Yahoo ist Teil von Verizon Media. Kenne Bell has been at this game for nearly 40 years. throughout the dyno run. For one reason you are going to get 2 opinions on how your car is running, which is better then one. (approx. This is going to seem basic, fact is dyno tuning uses fuel. MAKE SURE THE RADIATOR, INTERCOOLER HEAT EXCHANGER AND SUPERCHARGER INLET SYSTEM ARE VENTILATED PROPERLY WITH LARGE CFM ICED INTERCOOLER WATER – This is one variable that you need not be concerned with. 4. Intake and Exhaust. SUPERCHARGERS – The Kenne Bell Twin Screw is manufactured with such precision that it is virtually impossible for it to be responsible for a dyno variation. Anytime the engineer feels the transmission integrity is challenged, regardless of gear, the engine torque and HP is lowered anywhere from 10- 50HP via reduced engine spark timing. Cooler intercooler water does not increase HP. Forget about the OEM scanners. It’s unreasonable to expect that you’ll throw 20 new parts on an engine and run it hard for the first time on the dyno and not expect anything to pop up. TRANSMISSION & DIFFERENTIAL EFFICIENCY – Both suffer from a 3-10% mechanical loss. What is knock? At the dyno you can tune your car and stop guessing if the change you made actually did anything. How can one know if the sensor is accurate if it can’t be calibrated or checked prior to a dyno run – or if it can’t be compared to an accurate sensor reading? 21. They are simply WRONG and/or the result of problems unrelated to the supercharger and chip. This will confirm both whether there have been any losses or gains in power and the safety of the … The HP loss on any product that has more parasitic loss or restriction (headers, exhaust, inlets, etc.) The following is a short summary of the most important variables to consider when dyno testing. Once a good safe fuel and ignition calibration has been mapped in the ECU, part throttle and full throttle testing can begin. Since exhaust temp is largely determined by intake mixture and ignition timing, the engine computer is constantly monitoring these parameters via “cat modeling” which can affect power output up to 20HP. A noted and respected magazine writer brought his car from one dyno to another, and discovered a 1.5 difference in AF ratio. Get it? The rollers attempt to slow the spinning tires. 4. TORQUE MANAGEMENT – Calibration engineers now use ignition retard to “kill” HP for softer shifts and reducing transmission stresses. While a dyno isn’t going to place any more stress on your engine than driving it at full throttle on the road, if your engine is using oil, smoking heavily out the exhaust, pushing water out or generally in poor health, your dyno session probably isn’t going to end well. SUGGESTED DATA TO BE RECORDED DURING DYNO RUNS. However, when the vehicle is re-tested with an ECM or Horiba or a Dynojet with a fresh sensor installed, it checks O.K. An excessively rich or lean mixture can ruin or partially damage a converter, create additional restriction and skew a dyno comparison. To avoid this variable, use the air temperature at the entrance of the filter. IF YOU WISH TO OBTAIN THE BEST HP AND TQ VALUES, RUN THE VEHICLE WHEN AS COLD AS POSSIBLE (however, make sure If the HP is identical in all gears, get a new dyno. 2nd and 1st gear will make progressively less power. We’ve observed 20HP variance between 2nd and 3rd gear or 3rd and 4th gear. SWITCH CHIP POWER MODE There can be other contributors to excessively lean or rich mixture. 9. When we think of tuning, most people immediately think of a dyno and when we have the option to tune on a dyno, this is usually going to give you the best possible results. They are typically operated by the vehicles computer so the engagement and/or engagement rpm, speed and gear may be modified. If you are interested in setting up a dyno, here are the basics. Dyno Proven. Do the cars vary or is it the AFR readings that vary? Dyno Day Information. We’ve seen 30HP variance in runs. You can bet your house on one thing: Ford, GM and Chrysler don’t calibrate their vehicles with these low cost dyno sensor systems. We hope you find it informative and helpful. In most cases, a typical dyno tune is about making sure there is the correct air to fuel ratio to support the rpm and load on the engine, as well as to optimize the ignition advance curve to suit. I never wasted my time chassis dyno testing a vehicle until 1995 when Dynojet demonstrated their big The ET will vary with driver, traction, gears, tires etc. We’ve been doing it for 40 years. Why Both? The data from other dynos that take into account aerodynamic drag and road load is of no interest whatsoever to us as we cannot compare the data to our dyno or any other Dynojet. Isn’t the cool air in the fenderwell cooler than hot air from the engine, headers and radiator? Select a dyno that also uses SCT (Superchips Tuning) (407) 774-2447 software and the SCT Raptor Diagnostic Data Scanner so you can look at the ignition timing, ACT, ECT, etc. ALTHOUGH TEMPERATURE WILL ALSO AFFECT THE SHOOTOUT HP AND TQ OUTPUT, THERE WILL BE LESS EFFECTIVE REDUCTION IN POWER – THIS POSITION WILL ALLOW FULL SPARK TIMING UNTIL REACHING HIGHER ENGINE OPERATING TEMPERATURES. We also answer what exactly we mean by engine tuning. can vary, but we’ve never seen an OEM Ford, Chrysler or GM computer “fail” or “act up” in 20 years. Read on. And a come on for someone who wants to take your money. When you do this, you will be immediately moved into the car for carrying out the dyno. The question that really bothers us is when the customer compares 2 dynos and then asks Kenne Bell which on is right, the 14.1 or 13.1. Your best option is to take your bike to a garage or shop that has the dynamometer and other equipment needed to do this specialty tuning offers … DynoTuning for Modified and Customised Vehicles. Für nähere Informationen zur Nutzung Ihrer Daten lesen Sie bitte unsere Datenschutzerklärung und Cookie-Richtlinie. Unless you own a garage or work at one that has the right equipment, you usually won’t be able to dyno tune your bike on your own. Neither Kenne Bell or the OEM calibrations vary on a stock vehicle. When you go to extreme modifications > 50% gains, you will have to be prepared for parts to break and severely shorten the life of engine and drivetrain components. Dwell or pulse width is how long the injector is “open” or “on”, which is a simple calculation. UNDERHOOD “HOT AIR” FILTER TEMP MEASUREMENT – If you must use one of these things, then never measure air temp at the top (cool side) of the filter or the bottom (hot side). Before we run your car on the dyno we will carry out a pre-run diagnostics to make sure your car is in good working order before we start. See if the dyno operator will give you the actual dyno run files on a disc. Fleet Car servicing specialists. This takes the guess and disappointment out of ECU upgrading. An ECU device is used to modify the parameters of your vehicle’s engine control unit according to exact specifications. In 1960, I dyno tested my 5500lb ’59 Buick Invicta on a friction dyno. can make any HP number you want and vary the dyno readings 50, 75, 100, 125HP. 3. 12.5:1) are optimized, there is no other magical or secret 3rd, 4th or 5th dimension to making maximum power. No way. Do you really think that the OEM’s just sit around and wait for duplicate 70° and 30% days to run a comparative test? Inaccurate AF ratio meters are our number one customer service problem at Kenne Bell. 200HP, 220HP, 190HP – which one should I have used? In a nutshell, the dyno is used to apply a load t… When we Dyno tune your vehicle we are performing a car tune-up of the highest quality, using a measured and systematic approach, which will provide you with more power, and the smoothest, most economical performance possible from your vehicle. What does that tell you? Vary these two and your engine may or may not vary much – or it may vary considerably depending where the baseline timing and AF ratio were. Circle track engines and those that are destined for street only … Typically run automatic trans vehicles in 3rd gear and 4 speed cars in 4th gear. The result is a fast car that will remain in top condition for a long time. Our customers tell us that the sensor furnished with the Dynojet Dyno is approx. Note: At Kenne Bell, we use the unsmoothed curves as it has proven valuable in our analysis and data collection. However, initial … We use expensive “industrial” sensors that cost 2-4 times more than those “automotive” sensors used on dynos and in car AFR meters. In addition to our HP test data and graphs, we publish complete boost, pulley size, ratios and even 1/4 mile times accompanied by the Kenne Bell “Tech Tips” for the specific vehicles and kits. The addition of a supercharger and the change in sound wave frequency also changes the sensitivity of the sensors and can alter ignition timing and HP i.e. FUEL PRESSURE IS HANDY IF YOU CAN GET IT. Sie können Ihre Einstellungen jederzeit ändern. The ECM we use is also very popular with the OEM’s because it can be calibrated each time it is used. IMO, the best place to tune is a local track Test and Tune. Comparing the advertised horsepower claims on high performance products can be both confusing and misleading. They, of course, had to be re-tuned. ECT – The ECT (engine coolant temp) sensor also adjusts engine timing and fuel based on engine coolant temp so be sure it’s the same when comparing runs. Oops! Finally, do not generate any new unnecessary variables for yourself. Modified Nissan 350Z tuning stages. Through accurate loading and simulation of road conditions in a controlled environment, dyno tuning saves you time and money from unfounded diagnostics and actual street driving. Also changing from a HOOD OPEN vs. If you lack the equipment to stabilize timing and/or eliminate knock – or you’re sneaking up on a tune, it’s better and safer to step up to racing fuel and eliminate the variables. And yes, a Cobra IRS rear is 3% less efficient than the non IRS (3% x 400HP = 12HP). Please let us know! Just because is pandemic, doesn't mean you should neglect the maintenance of your car. We’ve measured a 40° difference from top to bottom on an ’03 Cobra with an open hood and a dyno fan. Stage 3 competition upgrades just don't work well on the road difficult in stop start traffic. SHUT OFF THE TRACTION CONTROL SWITCH PRIOR TO ANY DYNO RUN. At Kenne Bell, we run thousands of dyno tests every year on a variety of vehicles. 16. We’ve seen 10-20HP loss before the pistons went South. Dyno Tuning vs. Street Tuning. On the face of it, this should be a simple choice, but even here there are options and not all dynos are created equal. This will ensure a successful dyno day. Let’s take a closer look at how and why dyno horsepower claims may vary – knowingly or unknowingly. If you know your engine isn’t healthy it will be cheaper to fix it before you end up with a hole in your block! How in the Hell can anyone determine which one made power and which one didn’t? In the ’50’s, I would tune my new cars at the Pomona Drag Strip by being first in line when the gates first opened. There can be up to 15HP between 11 and 12.5 AF ratio. This list of common problems should help you achieve this. 10. Dyno to dyno, Dynojet tests should be quite accurate, within 10HP IF THE DYNO IS CALIBRATED CORRECTLY, THE IDENTICAL “SAE”, “STD” OR “UNCORRECTED” CALIBRATION IS USED AND THE ACT READING IS MEASURED AT THE FILTER. You Are Here: Home / Remapper / Benefits of engine tuning and why you should remap your vehicle? We often “lock” or “fix” the voltage to a sensor to totally negate any possibility of AF or timing variations. For example: A GM 12 bolt rear is 93% efficient whereas a Ford 9″ is 89%. These sessions ensure your car is running at the top of its game. The exhaust is black and the scanner reads rich, so it’s rich. We all like “big” numbers, but it is the ability to improve a vehicle that makes the difference between social media braggers and actual racers. Then it will run better than just "good," it will run at its optimum. Tweaking is not necessary. NOTE: Kenne Bell will only consider reviewing DynoJet Dynamometer horsepower and torque readings, as some other dynos have been proven to be inaccurate. Since 1° of timing equates to approx. Then you can at least be comparing apples to apples. Do you have other automotive performance topics you'd like us to cover? 26. This is a variable (multiple product testing) that should be avoided if the true loss or gain of a single product is to be determined. No 3rd dimension to tuning. If using one of these Power Speed Calculators, look ONLY at the 1/4 mile trap speed to compare HP. Damit Verizon Media und unsere Partner Ihre personenbezogenen Daten verarbeiten können, wählen Sie bitte 'Ich stimme zu.' More on that later. 18. noone really needs a dyno tune most times unles they care about getting the best adjustments. You may get good/bad numbers, but until you actually run your car 3-4 gears at WOT, you'll never know if your tune was worth your money. We’ve compared chassis dynos and engine dynos to chassis dynos. A … OEM parts have been used on many 600+ HP cars…there is no need for expensive plugs wires on most applications I am familiar … That’s how they solve the problem. DynoJet 424LC2 with Linx - the most advanced dyno that DynoJet produces. CATALYTIC CONVERTERS – First of all, we’ve never seen a “hi-flow cat” that makes more power so don’t bother removing them unless it’s a race car. It is precisely this confrontation or crisis that we are attempting to avoid by posting this information for our customers. We recommend hiding the switch so only you know where it is located to prevent someone else from inadvertently changing it to Shootout mode without your knowledge. A Ford AODE trans is 93% with converter locked up and 84% unlocked. Posted on Jun 10, 2020. Point the trigger nozzle on your hose into a bucket and squeeze the nozzle for 3 seconds. We know all the games, tricks and variables about making horsepower “numbers.”. Follow all other safety guidelines as instructed by your dyno operator. 36% less fuel and no HP drop. That’s the way we do it. And we’ve compared all dynos to drag strip times. The debate between car enthusiasts as to whether you should you should have your tuning done on the street or on the dyno brings out many opinions. Jan 26, 2017 himanshu No Comments Each car that leaves the production line of a factory is actually unique. TORQUE CONVERTER LOCK UP – The difference between the torque converter clutch engaged or locked up is 20-30HP. Both sets of data are necessary for a valid analysis and comparison (see attached Minimum Suggestions and Guidelines). drum inertia dyno. When we think of tuning, most people immediately think of a dyno and when we have the option to tune on a dyno, this is usually going to give you the best possible results. They knowingly jack up or inflate dyno numbers to promote their tune or products. Allow to stabilize. Main Reasons for Dyno Tuning. We are only attempting to make our customers aware of the ways HP readings can vary from dyno to dyno, vehicle to vehicle etc. With a boost or vacuum leak, the … The engine shop at DMC2 Products, a company of Van Industries, Inc., can help you with dyno testing and so much more. TESTING 1 PRODUCT AT A TIME – Some still prefer to test a product – but in conjunction with another product or products (see “Supercharging vs. A dyno must be re-calibrated for any temperature, relative humidity, vapor pressure or barometric pressure change. 15. Sorry, but Kenne Bell has had enough of the “cheapie” sensors supplied by the dyno manufacturers. Dynojet has assured us that they are working with their customers on an improved maintenance program. This includes up to 3 horsepower pulls or 2 HP pulls and a 1/4 mile run (2WD vehicles only). BEST RUN – WORST RUN – We suggest making 3 runs to establish accuracy and to verify that there is no “best” or ‘worst” run variation. And remember that the vehicles IAT sensor operates INDEPENDENTLY of the dyno room temp. 1. 3.08 to a 4.30 rear gear set is a 3% reduction in efficiency. Horiba and ECM also supply OEM grade air fuel measurement systems. Investing in a wide band O2 sensor like the MOTEC they sell is also a good idea. On a stock motor, overall results from a CAI … Leaks in the Intake. If you ever have to question the integrity of a dyno run, request the dyno “hard data” (correction factor, temp, relative humidity, vapor pressure and HP and torque printed numbers) and the SCT Raptor data. DYNOJET DYNO ACCURACY – Kenne Bell is their biggest supporter. At least that’s been our experience for the last 20 years. A properly executed tune on a dyno will tailor the settings to the actual condition of your car. Run the engine “hot” the first time, let the dyno fan cool it down and then run it “cold.” The cold run will typically make more power. However, if you are introducing new variables such as injectors and mass air meter or products and combinations from other companies that Kenne Bell does not support, then you must seek out a custom tuner. The Dynojet also has a “STD” correction factor which is around 3% higher and used by some dyno operators who must show higher than SAE numbers for personal gains. They also can be very inaccurate, unless exact lab procedures are followed. The point is to make your car better. 10 sec and 10 mph. We prefer to steer clear of the realities of tuning on the street. If he won’t, you should consider going to another dyno. 28. We wouldn’t rush to blaming the dyno itself for HP variations. And be careful you don’t ice down the ACT sensor, or you may also alter the timing and AF ratio. How to properly tune up your engine "In tune, perfect harmony." We recommend the more expensive Horiba, ECM or Powertrain Dynamics.Tuning is complex enough without injecting another big variable. I find it interesting when you said that a possible way to tune cars with automatic transmissions is to get an ECU so that they can shift faster. Even if Max Pulse Width = 2 x 60 ÷ engine rpm 6000 = 120 = 20 milliseconds. Either test with the inlet system iced on every run or leave it as is. Using the vacuum of the … NEITHER! Therefore, if for any reason, an engine knocks and the knock sensor automatically retards timing, the HP will be less. This will cause the car to run lean at part throttle but rich at wide open throttle. No magic. It allows YOU to tune YOUR car on the dyno or at the track using elapsed times between known rpm points. the only other test is driving and thats more subjective. FUEL OCTANE – More boost, leaner mixtures and advanced ignition timing require higher fuel octane to avoid knock/detonation/pinging. Excessive boost can also cause the engine to knock and lose power. Read Stock ECU We will read the existing contents of the ECU allowing Celtic Tuning to modify the software for more power and allow us to revert it back to its original state should you wish to do so. are but a few of the variables that can affect a dyno reading. Dyno tuning should ensure that such a negative reaction should not occur. The customer doesn’t heed our advice when we argue that the dyno says it’s 13.1, but it’s really 11.1. If the engine knocks, reduce the boost and eliminate the timing variables. Our 4.6 2V Mustang test car once made 652HP with 3.27 gears, an automatic trans and locked up converter. If I look at your car when it comes in and notice a potential problem, I will turn the car away and your deposit will not be refunded. And this by no means implies that Kenne Bell is right and dyno AFR’s are wrong 100% of the time. These “hot air” underhood filters are a big variable in dyno testing. For the purposes of this article, we will be looking at chassis dynos where the engine is left in … This Raptor will print out the timing, commanded AF ratio, ACT, ECT, etc., etc. 1. Taking your car to a dyno tuning garage is the best way to not only improve performance, boost horsepower, and make the engine run more efficiently. I don't have a camera to show the 2 places that there might have been hoses but perhaps … We won’t get into the many specific examples that we’ve documented, but there has been far too many reports where “the car is so lean we’re afraid to run it.” Our customer panics. For example: An out of balance tire or a slight ignition misfire could show up as spikes that shouldn’t be disregarded by smoothing. There are no secrets.
