Not sure how many of you guys visit S2 forum but dimitri (PRJ) started releasing all of his info and mods for the stock motronic! He started a wiki that tells and gives everything you would ever want to know about the ECU. Check out for how to tune your stock motronic and get VEMS like results from it.

Man, that's got huge implications going forward. Especially for my winter car project, where I'm trying to keep my total cost under $5k CAD. Thanks for the link!

This is incredible.

I had given up and bought a VEMS, I may try this motronic tuning thing just to get my reliable -30 cold starts back, haha. I've got a stack of ECUs in the shop now that might not be so useless to me.
