I was looking into the Racelogic unit but there are apparently issues adapting it to a C6. On top of that it works by cutting injectors and since I'm spraying meth that doesn't really work for me. When researching I found this: http://forum.efilive.com/showthread....ontrol-Tuning/
Some of the terminology is different since it's EFI Live-speak but basically he (swingtan) is tuning the max engine torque vs gear vs rpm table (which, by the way, is maxed out in my stock E40 tune) to cut the ETC back when TC kicks in and tuning it such that it doesn't fall on it's face when it does. This is what I want to do and I want to come up with a methodology to tune it.
I want to set up a histo that plots the delivered torque against the max torque vs gear vs rpm table when no wheel slip exists. I don't see a wheel slip PID. I tried creating one which was driven wheel speed divided by undriven wheel speed but since my wheels/tires are not the same diameter it didn't work too well. Then I thought I could use "traction control torque" which is a percentage from 0-100% but it doesnt seem to mean the percentage that TC is kicking in. It seems to be a percentage of torque the engine is putting out in relation to desired engine torque, which for me is static at 483 foot pounds. Maybe that is because the TC max torque is set to 479 foot pounds? There is also "traction control desired torque" which is also a percentage and it seems to stay at 100% with my current tune. Now that I think of it I may have turned off TC for these logs. I'll try logging some wheel slip with TC on. That way I could just filter on TC Desired Torque <100% maybe. I need a way to determine that the wheels are spinning. Then the histo will plot the max delivered engine torque against the max torque vs rpm vs gear table and I will plug that into my tune. Figuring out a way to have it plot against that table in all gears is tricky too. I set up a histo using that table and it is only one row. I'm only really concerned with 1st gear right now but once I get it working I would want to do 2nd and 3rd. After tackling that I may need to play with the values in the ETC TPS Max table to get it to kick in enough or not too much.
I've attached a log and the config I'm playing with if anyone wants to lend a hand.
