Traction Control Tuning

[swingtan]

Good work Stigmund, did you log the runs? I found the best acceleration was achieved when I was getting some constant slippage while ramping up through the gears. It's a good idea to do a few runs with TC both on and off to compare the ramp rate. Then you can see where additional tuning might help.

no didnt log tonight but we have a proper strip night coming up. To make life simple can you list the pids you logged with as I am currently using a specific set.

I used your 1st and 2nd gear settings then for 3rd copied 2nd and added 15 to each cell, then copied 3rd to 4th and add 15 etc

For the TC tuning, I just look at....

• RPM
• VSS
• ETC-TP
• APP
• SparkAdv

The 2 throttle PID's help to show when TC is active, as does the commanded spark compared to the high spark table in the tune.

Then I compare the shape of the RPM and VSS lines between runs to see the effects on acceleration. Obviously, steeper lines in the graph mean faster acceleration.

Well..

I have my road runner installed. I will be tuning this a bit in my car these coming days. I am going to strap my car down on the dyno and test and Tune b1902 FIRST. After that it's more or less b6612 to have a complete control of what torque output you get. I believe that once you set both of those tables on the LS1, the rest should come quite easily.

The problem is that when you really want it which is on the WET... torque needs to be cut even more or you will get wheelspin and dangerous situations.
