There is only really one option open for the MPI where programable ECU's are concerned and that is Megasquirt with the latest siamese coding. The only other possable option is CANEMS, oh and perhaps Polestar, but Megasquirt is closer to the mark on price
Sprocket, I've read some of your posts, both on here and on EFi minis and seen what you've done with your SPi. I'm interested in another ECU, but to be honest am a bit of a ludite about things electrickery. I've looked up megasquirt on Google and (its probably me!) but it could just lead to further confusion. Is there a website/thread that puts things into laymans terms i.e. explains wideband sensors, siamese coding etc etc?
Cheers,
Graham
