I was looking around a few years ago for custom ecus that one could build up, and self tune. At the time, offerings from diy-efi (Efi332) and Megasquirt were available. I considered Megasquirt, and downloading as much about it as I could.
Changes in motors and cars however, along with no mods that really required a custom ecu put it on the backburner.
Now though, with the Carina, and subsequently turboing it on the stock ecu, we discovered that we had reached the limits of the stock ecu's fuelling capability, without adding auxillary devices like S-AFC's and AIC's.
Please note that this was the first Megasquirt install I did, so things would be fair bit different now. Feel free to hit me up on the forum if you've got a question.
So in January, I asked around and purchased an ECU that was just about finished. It had been circuit tested, and I only had to mount it in a case and solder a couple of FET's (Transistors) in. Even though that was all that was required for the ECU building, it took a fair while to do.. and there's more then just the assembling to worry about... loom, Engine stuff...
