higher octane fuel does not produce more power. A noted and respected magazine writer brought his car from one dyno to another, and discovered a 1.5 difference in AF ratio. 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. Our technical editor, Robert Pepper, is here to answer your questions about, well, technical and this week he talks about whether you should tune your car engine. NEITHER! In addition to that, before having it installed in a car, a driver must buy it from a trusted local dealer.

We have reached the point where the current inaccuracies of dyno and in car AFR readings with “wide band O2 sensors has created so many problems for us that we are hesitant to even recommend our customers dyno test their cars. All Kenne Bell dyno tests are run that way – unless, of course, you want a dyno run with less power. 35. 200HP, 220HP, 190HP – which one should I have used? GEAR SELECTION – The trans gear ratio that is 1:1 will make the most power as it is the most efficient. 34. Fuel octane, by itself, will not affect dyno HP i.e. SWITCH CHIP POWER MODE If your arrive with MSD parts on your car, I will tune it, but if the part fails while tuning or is bad from the start, there will be an extra charge or your car may not be able to be completely tuned and you will still be responsible for all of the tuning fees. Then you can at least be comparing apples to apples. After 20 ms, the engine is coming around for another cycle so that is all the time the injector has to supply fuel. How does one know when this is happening on the dyno? Kenne Bell clearly states the power gains to be expected by advancing timing and leaning air fuel ratio. Modifying cars in the UK generally do not add value to your car and you should be aware that in most cases will devalue the resale value of your car. 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. This is going to seem basic, fact is dyno tuning uses fuel.

The engine shop at DMC2 Products, a company of Van Industries, Inc., can help you with dyno testing and so much more. INLET TURBULENCE – Turbulent air flow from the engine fan will affect the air flow into an underhood air filter and more importantly, the mass air meter. If he won’t, you should consider going to another dyno. 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. Once I got all 4 corners jetted ideally – I would know when I had it right because the 1/4 mile speed wouldn’t change or it would drop – I’d turn the distributor 1° at a time with a special “adjustable screw cable” I had designed for testing. 10 sec and 10 mph.

Testing can last as long as several days trying to maximize performance by trying different parts and dyno tune … FOR RUNNING YOUR CAR / TRUCK ON THE DYNO We often “lock” or “fix” the voltage to a sensor to totally negate any possibility of AF or timing variations. There can be other contributors to excessively lean or rich mixture. It doesn't matter what make and model car you have or are looking at tuning, this course will be applicable. No 3rd dimension to tuning. MPH vs. RPM – Higher numerically ratio gears consume more HP, which is more apparent as vehicle speed increases. Lose it! and other data from the OEM computer in real time.
