Another newbe to tuning, I am tuning my L61 cavalier, working on the the VE tables at the moment. I am tuning the VE tables using AFR error, tps and rpm, my question is on the histogram, for the TPS axis, I have 3 options with all different readings. I can use 2 PIDs, TPS and TPS (SAE) or sensor TPS. the PID TPS is the only one that reads from 0-100%, TPS (SAE) starts at 10% and TPS sensor starts at 5%. could anyone offer some guidance please?
