Use maximum traction while accelerating. Humans' reaction time and inputs to the throttle pedal are measured in tenths of a second. Electronics can react in a fraction of a millisecond - this is where the secret lies.
There is no fun in driving over an ice patch or a wet kerb in RWD car. If your hands are quick enough, you can recover from a spin. If not - you crash. RaceTCS will help you limit engine torque and reduce slip, giving you more time for reaction.
If you are a beginner driver, you will most certainly fear of using full potential of your car. The risk is highest in RWD cars, where too much power might result in a side crash. Adjust the maximum allowed slip to your liking, so that you can enjoy the loss of traction, but always have a guardian in case you go too far.
RaceTCS started as a hobby project. It was supposed to help Saab 900 (2.3 turbo) use less tires :). Without traction control it had wheelspin until 100km/h and wrecked front tires in one summer season. Development slowly progressed until 2013, when the project needed a better development car.
In 2013 a new car with much more potential for track racing appeared. It was designed from the beginning to have Honda K20 engine in it. The swap took (as usual) longer than expected. During that time road tests of RaceTCS were not possible.
In the summer of 2014 the car was finally ready to drive. It took part in the first track racing events and was great development car for RaceTCS.
As it turned out, with barely 200hp from NA K20 engine and a stock LSD, traction wasn't a big problem even in the wet. RaceTCS was already performing very well, but required a more powerful test car. Decision was made to install a supercharger.
First tests with supercharger. Almost 300bhp turned out to be handled well by RX8 chassis and RaceTCS complemented the whole package. That year the car (and driver :)) won trophies in a number of local events. Also it was the year when first test RaceTCS units were delivered to other car enthusiasts and were very well received. The circuit board was still a prototype, the case was 3D printed. By the end of the year a few 350z got RaceTCS.
Amateur racing continued as well as development of RaceTCS. New version addressed shortcomings of previous version - circuit board designed to match the case, USB port and internal changes to support both VR and Hall effect sensors. PC app for logging and configuration was created.
Commercial version was created and delivered to first customers. Firmware and PC application were constantly improved, reducing reaction time and improving logging speed (~1000frames/sec). Test cars have been running RaceTCS for 2 years now without any engine problems.
RaceTCS is a universal aftermarket standalone traction control system. It uses wheel speed sensors (usually used by ABS system) and intercepts fuel injector signals to control engine torque. It does not rely on any existing car electronics,except wheel speed sensors.It works in similar way to other known systems on the market, like Racelogic traction control system.
RaceTCS replicates injector signal coming from ECU and when torque reduction is needed, it cuts whole injection pulse. There is no way that part of the fuel can get into the cylinder and cause lean burn. Since 2015 , when device was delivered to 1st test cars, there was not a single report of damaged piston or valve due to RaceTCS.
When RaceTCS cuts injection pulse to a cylinder, that cylinder cools itself with incoming air. Because of that , EGT is lower in cylinder , which was cut.
A list of cars, in which RaceTCS has been tested (alphabetic order):
BMW E36 (with M3E46 ABS system and stock ABS)
BMW M3 E46
Fiat Coupe 20vt
Mazda MX5 NA
Mazda RX8 (K20, 2JZ, SR20DET, Z32SE)
Nissan 350z with both with VDC and just ABS (US version)
Opel speedster/vx220 2.2 and turbo
Seat Ibiza 1.8t
Toyota Celica 4wd (viscous clutch)
Toyota Celica FWD
Shipping to EU countries should be 7 days with parcel service. Shipping cost is around 20 euro for whole EU.
Package contains RaceTCS device, USB cable, slip adjustment potentiometer and indication LED.
Installation requires experience with multimeter, soldering iron and ability to read electrical schematics.
List of recommended workshops will be growing with time. We recommend :
MAX-Performance Al. 11 Listopada 156, Gorzów Wielkopolski, 66-400 Poland
Turbo Lamik Gwarków 53, Lędziny, Poland
Zen-TE Łódź, Pabianicka 10, Poland
Adjustment is done via 10 position potentiometer with a knob (included in the package). It can be hidden (e.g. in ash tray) and should be mounted within driver's reach. Drilling a hole to mount the potentiometer might be required.
Very few cars have stock TCS that is performance oriented. For sure you tried to drive on the edge with your RWD car and traction control slammed on the brakes. It cut the engine power and you could not accelerate for a moment. This slows you down. On the other hand, when it is slippery, you might be afraid to disable traction control completely. If you feel that your stock TCS is too strict, slows you down and takes the fun away, then RaceTCS is your best choice.
RaceTCS in no way affects stock TCS or ABS. It uses the same sensors as ABS, but operates separately. You can have stock TCS and RaceTCS on or off separately.
RaceTCS is active as soon as you turn on the ignition.
