It would be awesome if we could add more to this, but I'll start off, here are an MY02 WRX ECU (Prova-tuned A4TE000A) vs a MY02 B4 (Me-tuned A4SHC01H) ECU, both MT.
I Have marked down parts that are present on one ECU that are not present on the other. I would kill for an STi ECU to compare against the two of them also (This WRX one was meant to be an STi one but turned out not to be). I have not marked down any absent parts.
B4 ECU - AG443
WRX ECU - AH750
