My project car is a 1st gen Saturn I've had for years.
I've been working towards turbocharging it, but I always find myself in the research/engine=can o' marbles stage.
To this end I was originally looking at various hacks of the stock PCM (once I was intelligent enough to realize it wouldn't magically work). Then I moved up to the MS, but started to think that it wasn't much better than hacking the stock PCM or jury-rigging the well-abused GM P4 ECU to work. So I started looking into putting something together myself and stumbled upon this site which seems to do almost exactly what I was thinking of and even seems to use the same major IC's I was thinking of designing around.
I'm hoping to be able to get the VEMS up as a complete replacement for the stock PCM with all the lovely joy that comes with it. After that I want to work on IonSense to compensate for the noisy engine and low resolution crank sensor. I have a bit of experience in some small embedded system projects and some in C, but I'm mainly a hardware guy.
Just flipping through the wiki to see what's going on for now.
If you could come to irc at least once (see ListsAndForums) we could discuss some "project" stuff, eg. on collaboration for CDI and IonSense board(s).
