I'll start off by posting my project. You can expect tuning tips, hints, tables, maps, etc. from me in the very near future. I'm towards the end of installing VEMS (stand alone engine management). I've got a few things to work out, but the car has been running and driving for weeks now.
I should do a proper write-up here, but as it stands all the progress is hosted at the terrific VEMS forum run by Rob. I have tons more pictures ready to host when I get the time. Check out my progress there at this link:

If you're really interested, I've been doing VEMS on two cars. Check out my friend's BMW too if you'd like:
