Traction control speed sources

[Scott33]

I have a RWD car with a limited slip.  All four wheelspeeds are plumbed to digital inputs.  I race on road courses with fairly low power (200rwhp with a 2500lbs/1130kg car+driver+fuel).  I would like to tune traction control to help with mid-corner to corner exit.

What should I use for the non-driven and driven axle speeds?  Average or max?

I started with average, but I do notice that on initial throttle, the inside wheel speeds up a bit before the LSD.  I'm wondering if I should be using max, or maybe ideally I should be using "outside wheels".  I know I can't set that up in Link, but I have another ECU that can process CAN messages and spit out whatever I want, so I could add inside/outside detection to the other ECU and just send back outside wheel speeds back to the Link ECU.

Any ideas/tips?  Thanks!

From memory when testing with an xr6 turbo Falcon we found using the Outside wheel worked best (G4X has an outside option which uses the accelerometer).

You might be able to screw around with GP PWMs and accelerometer stuff to make an approximation of this in G4+ but I wouldn't be certain this was possible until I gave it a go myself, otherwise I would say give Max a go as that should be the same as outside in a lot of situations.
