ok im planning on buying this ecu from somebody on h-t. but the thing is that his friend gave it to him, so he doesn't know what kind of car it came out of exactly. i know it's a p75, but that's all i know

my question is from the code on the side of the ecu, can i find out if it is an obd-1 or obd-2 ecu. also if i can find out if it is from a manual or auto.

hopefully it's a obd-1 p75 that's manual

here's the code on the side
37820-p75-951

3 plugs obd1
4 plugs obd2

Uhhh, actually 3 plugs means manual, 4 plugs means automatic...

OBD I ecu's only have 3 sections of plugs; OBD II ecu's have four sections, but only three of the sections have plugs, one is blank...

 

That ecu in the picture is an obd1 P75 for sure

 

its an automatic obd1 94-95 Integra LS ecu

 

Hope you don't plan on chipping it......

 

aww man it's an auto. that sucks. i guess i have to keep on looking for another ecu

 

I am trying to do a 90 crx dx to zc swap, and its an automatic I think I need an obd1 automatic ecu to do this swap, do you want to sell the one you have ?

 

You know, you can convert the ECU to manual. Search around for how to do it; I think it only involves moving a resistor around. Might be cheaper than finding a whole new ECU.. Just a thought.

 

how can you tell that it a auto ecu?
