is there a way tou can tell the 2 ecu's apart.. i forgot what one was auto and what was was manual that i have.

 

obd1? what ecu?

 

pm5

 

I dont believe the PM5's came in auto...

Try looking in the PGMFI wiki

wiki.pgmfi.org

 

well then can i use a auto ecu on a manual and it wont know the deferance?

 

pm5 is a dpfi it's not chippable and is good for shooting with a 9 mm. No you will get auto code and the car will run like assssssss.

 

it won't run like ***, it will just throw a code 19, so your CEL will be on all the time. you could pull the lockup solenoid off a junkyard car, and hook it up just to make the ECU happy. that's what i did with a P28 auto... it wanted 2 solenoids, but i only had one on the tranny, so i threw on a dummy solenoid.
