looking to convert to obd1 so i can run uber on my 97 civic. already had the conversion harness just got this p28 today.

can anyone tell me why the p28 has the obd2 style connections ?!?!?!?!?1








thanks!!

because its an OBD2 style ecu?

 

p28 is an obd1 ecu tho?! am i mistaken lol. im 100% sure it came out of the 92-95 ex

 

where did you get that ecu? it looks like a p2p with a p28 casing......most obd1 ecu's have an open spot where a 28 pin socket an eprom can be soldered into like this:

 

a friend online. he got the ecu with a complete y8 swap. never did the swap and bought a nissian. he's a guy i've been talking to for quite a long time. he was never able to test it and said feel free to send it back if it doesn't work. i haven't even payed for it yet so i trust his knowledge of the ecu..which is nothing lol

 

circuit board layout is identical to my p2e with a few differnt peices but the layout is identical.

 

you said that ecu came from a buddy that bought a complete y8 swap right? its possible that the y8 swap he bought came from a 96-97 del sol si which came with the y8 motor.....and it could very well be an obd2 p28...

 

obd2 p28? wow i've never heard of that. i can ask my buddy about that but i've never heard of an obd2 p28

 

Yes Y8 is definitely OBD2.

 

i know the y8 is obd2. im talking about the p28

 

yep the 96-97 del sol si had the obd2 p28

 

there is also no OBD1 Y8 engine, the sohc vtec d16z6 is obd1, y8 are 96 -00 OBD2

 

you can get an obd1 ecu with 2a and 2b plugs.

hondata sells p28's with obd2 plugs.

100% dead on. I have one of those sitting here too.

 

ya i was thinking it might have had swapped connections but the board is deff identical to my p2e.

wow you learn something new everyday. i suppose this must be the 96-97 del sol si obd2 p28
