And I don't think anyone really made the OP understand what he was asking. I may be mistaken.

But EVERY car has an ECU. Well.. Fuel Injected anyways.

ECU's are stock. They come from the factory setup for your stock setups, nothing more. Some can be tuned, with settings being able to be changed on a stock ECU to allow for more timing, larger injectors, etc.

ECU Stands for Engine Control Unit.

Motec, AEM, PowerFC, MAP ECU, etc, are ALL ECU's. But they are user programmable, so you can use them with your modified engines, to allow full control over your motor.

So before I get in over my head, every car has an ECU. Engine Management is something you can tune. Basically.

*Edit* Haha, still on Carina's name. Ooops.
Don't forget about a piggyback on a stock ECU. I'm not a huge fan but there are plenty of cases where they work well enough to get the job done.

I got more interested in Megasquirt's (hence the MS in eMS-Pro ) capabilities after having dinner with the founders, software engineers, programmers, etc. The eMS-Pro is indeed the MS1 chip but with the MegaSquirt 'n Spark/Extra firmware adding boost control, nitrous, fan control, programmable outputs, water injection...which I think is standard on MS1 now so the eMS-Pro is nothing more than a pretty box and better connectors. Upgrading to MSII is only $60-100 more and I'm not sure the latest status on v3 but it's probably what I'm going with...
