aceTCS uses input from wheel speed sensors (used by ABS) and controls single injection pulses of fuel injectors. When it detects a slip condition and the slip exceeds allowed limit, it cuts the signal to fuel injectors. Because fuel injection happens every few milliseconds (depending on engine RPM and number of cylinders), it reacts very quickly. You can't feel it working, you can just hear the change in engine exhaust sound. It is completely safe for the engine (turbo, supercharged or NA).It has been proven to work over the years on drag strips and race tracks in cars with as little as 140hp and exceeding 1000hp engine output. In contrast to the stock traction control system in modern cars, which are using throttle and brakes to limit power delivered to the wheels, RaceTCS with its control of fuel injectors can be much quicker and more precise. In addition, most stock traction control systems intervene very hard, making it very unpleasant to drive on the limit. Stock systems are not about performance, but safety. RaceTCS is about performance and safety. RaceTCS effect can be compared to modern ABS system. Human controls brake pressure for all wheels. Without ABS system, the pressure has to be reduced if one of the wheels locks up - otherwise you will burn the tire and the car will pull to one side. Modulating the pressure by foot is slow, inaccurate and unless you are F1 driver, it will result in sub optimal braking distance. The same principle applies to acceleration. When you lose traction, you lift of the gas, wait a moment until slip stops, then accelerate again. The process is very slow. RaceTCS keeps wheel spin in user selectable range, so you can extract maximum acceleration force from the tires.We will send a file via email for NA or vx220 turbo which will have all the base infomation on.
