Tc. Retard without real slip

Post by k20brasil » Fri Sep 06, 2019 7:44 am

Hello, see if you can help me, I have TC. Retard (small pulses of retard) as if they were interferences, even without real slip with car in low charge.
We always install in the same way (as manual) Grouds and etc, but I have these small pulses of TC retards and in the launch I have enough TC retard.
Thank you.

What are you traction control settings? Seems like your target is low and the slip to retard table high.

You need to take a datalog with both USBs connected so that we can see all the data from the traction control.

You appear to have the wheel speed sensors wired to the wrong wheels as it is showing that the right front and Left rear are both spinning much faster than the other 2 wheels.

What I am finding wrong is that are "pulse peaks " is not constant the wrong reading, see in the photos even in the vacuum phase in the collector without having as spining, we have a peak speed reading absurd and then returns to normal.

What sort of vehicle is this? Have you got the traction control box set for inductive or constant current wheel speed sensors?
