RACELOGIC Traction Control Manual V3.1 4. Fine Tuning
This section gives a few pointers to common problems associated with the traction control set up.
The following section requires the use of a laptop computer.
Q - The traction control reduces engine power before it gets a chance to produce full power.
A – The Minimum RPM before operation (Configuration tab, Minimum operating thresholds, Revolutions) can be raised. This is set to 2000 as standard. If the car is a high revving car it may need raising to where the car comes on cam.
Q - The car appears to cut on cornering when no wheel spin is being produced.
A - Using the real time function in the software check that wheel spin is definitely not being produced. If it is not raise the Minimum difference by 1-2 Km/h. This should allow the car to turn a tighter corner without the traction control cutting in.
Q - On all settings of the adjuster the car feels like it is being held back all the time.
A - Increase the Percentage slip values (Slip control tab).
Q - The car still over steers .
A - Reduce the Percentage Slip values (Slip control tab), and reduce Minimum difference (Configuration tab) by 0.5-1.5Km/h.
Q - The Car bogs down on Launch Control.
A - Increase the Launch control rev-limits (Rev limits, Moving rev limiter).
Q - The Car produces lots of wheel spin on Launch Control.
A - Reduce the Launch control rev-limits (Launch control tab, Dry/Wet settings).
Q - The car appears to bog down pulling out from tight junctions.
A - Raise the ‘Slow override speed threshold’ and ‘slip override for slow speed getaway’ (Launch control tab).
Q - The ABS sensors do not pick up until 18Km/h and is causing the traction control to misfire the car in first gear.
A - Raise the Minimum speed threshold to above 18Km/h. (Configuration tab, Minimum operating thresholds, speed).
Q - The traction control reduces the power enough on corners but in a straight line the car still wheel spins.
A - Lower the Straight-line override, this will reduce the slip allowed in a straight line. (Configuration, Turning).

Q - The car has different size wheels front to rear, which means the speed of the wheels is different.
A - Measure the diameter of the front and rear wheels and type in the Wheel diameter - Driven, Wheel diameter - Reference. (Wheels tab).
Q - In the software the speed of the wheels is different to the speedometer.
A - The pick-up points that the ABS sensors are picking up from are different to the value in the traction control. By working out the difference in speed to what is in the software, adjust the Number of pulses per rev – Driven and Number of pulses per rev – Reference until they are the same. e.g Peugeot 306 Rallye 24 PPR. (Wheels tab).
Q - The RPM value in the software is different to what is showing on the Rev counter.
A - The Number of cylinders value is incorrect. Adjust the value until both values are the same. (Configuration tab, Cylinders).
Q - Which is the best setting for dry weather?
A - The best setting for dry weather is down to the driving style of the driver. The adjustable system allows the driver to choose a setting which suits them best. We would suggest 10% slip as this has proved to give the best acceleration in tests, which is position 3 on the adjuster.
