Yes the ECU is massively complicated. I had to get it running from a totally unsuitable map that wouldn't even start the car. I've got it going and managed to set it up enough to drive it on boost and travel to Santa Pod in it. Had a few issues to work round and iron out of the map but it's getting there. If I had the time I'd carry on playing with it but I'm just too busy with work, hence why once it's ready I'm letting MSD finish it off.
The brakes are binding slightly and over braked on the rear. The back steps out if you're on even the slightest bend and for some reason that I can't find, they stick on and get hot and bind.
