I pulled my ECU and am trying to locate the part number to determine the manufactuer because the original owner didn't remember who he went with. Pictures, or insight would be great!

Thanks!

Default I dont' see any of those specifically...

when I bought the car, the original owner sent the "spare ECU" with it... naturally I would assume they put a new chip in the new ECU... rather than downloading it. I'm looking for the specific spot on the ECU I can find the chip, as there are many and I didn't do too well in my DC circut analysis class! Again, pictures would be great!

Default Here's an early APR chip...>>

The light green board. Note that EVERY chip from the factory is soldered in. If there is a Socket, that would be the aftermarket chip. GIAC, MTM, Neuspeed all use socketed set-ups..
