Problem with Traction Control Reactions

Post by BLR »

My traction control reactions don't seem to be working properly.
On the data log when the traction control kicks in it makes the initial adjustment but as the slip x time increases further timing and boost adjustments don't change. According to the data log the slip x time gets to 125, which should further adjust the spark retard from the initial 7* to about 12*, but it just stays at the initial 7*, same for the boost correction.

Any ideas on why the T/C reactions don't increase with the slip x time?

Yes. It's like MLV is off a decimal point.
TunerStudio's Slip x Time value = datalog # x 0.1
A 125 in MLV is the same as a 12.5 in TS

by the way: It would be helpful, when the slip_threshold is transmitted and saved into datalogs. (Especially for those people, who use adjustable slip threshold)
Same for Spark Cut and Add Fuel. This will make traction control tuning a lot easier.
