Never done anything computers interfacing cars but i want to do an EFI swap and i hear Megasquirt is the way to go.
if you have to ask
>>28778505Megasquirt is cheap and has a lot of support but none of it is centralised or easily available. If you're willing to spend a bunch of time searching and reading boomer forum threads and shit then Megasquirt will do everything you need it to do, but it isn't going to be as easy as getting a haltech or something that'll do most of the work of setting itself up automatically and has a support help line and whatever to assist you.
