thanks all, I have some free time this afternoon to play with those settings and I'll post up my results here.
Lance : I don't know any online MR2 owners that use the Wolf. This is ECU number 2 that Wolf have made for the 3SGTE (Stu's is the first I believe)... the settings differ between ECUs as oldcorolla points out.. so the settings on a Motec/Autronic etc are different to a Wolf. The principle is the same however.
To be honest also, I personally find the MR2 boards are more hinderance than help. Like All-trac.net. You post a question and they all start waffling on and not actually answering. I'll get a reply like "Why not use a Autronic", "Why not a PowerFC" etc.
Its just a matter of playing around that will solve the problem.
