bah, the biggest give away if its an auto ECU are if the transistors are there for the lockup solenoid etc:



wanna make it a manual ecu? remove RP17 and RP18, replace RP18 with a jumper wire

no, the fuel and timing maps are the same... other than having the extra outputs they're pretty identical. the stock tune sucks donkey *****, period

auto ecus on 5spd cars:
code 19

barcode reads on the ECU:
37820-P28- A50 or A51 or A52 or C50 or C51 and so on...second # being 5 means an auto ecu.

"whats a jumper wire?"

just a piece of scrap .. like say the left over leg from a cap or resistor as you socket the ecu

You can change it. I wish I had the threads handy on how to do it but I don't.

Here is my offer: If you ship me your ECU (P28 or P06) I will convert it to manual, install a 28 pin socket and add the 373 gate. All I want in return is the two transistors that control the auto transmission. You no longer need them. All you would need to do is send me your ECU and include $12 for return shipping.

If you are interested, let me know.

Nah, not really. I have a shitload of 373's, 28 pin sockets, and a nice soldering station. I need some 5151s for a turbo related P28 mod, and it's easier than converting an IR6220. It's still a pretty sweet deal for someone without soldering ability or PCB experience.
