What do I have to choose from for engine /fuel / ignition managment on a 20b? I already have a PFC but dont know if will work.

pfc will not work. you need something that will run at least a v6, at most you need 6 injector outputs, and 6 ignition outputs

so that leaves Haltec & TecIII...any others?

motec m800, autronic sm3 (when they release it), wolf has one, mike-ro-tech, and if you had the time and were that bored you could use a gm ecu



mike

do you know which of those have windows based tuning / maps? I plan on installing a compact "auto" PC and it would be nice to have something that will interface with it.

Haltech and Microtech fer sure

motec is still dos, because dos in this case works better



mike

A car PC is cool.

Yea, I've always wanted one and it dosent cost that much...about 20% more than a regular PC

I've been reading a bit about each one and am leaning towards Mocro-tech and Electromotive. I like the setup and having new ignition coils. It would also be nice to run a system that someone here is familiar with.
