[aust ek coupe]

does anyone know if there a such thing as a obd2a p28 ecu? im going down a buying a p28 off a guy today and he says its a obd2a p28 out of a 96-97 del sol.

[Brian]

no. P28 is OBD1

[aust ek coupe]

yeah thats what i thought. how long did they make the del sol?

[Brian]

....til 97

[aust ek coupe]

hmm well this guy saying its a special thing from being a del sol

[Brian]

P1Z was the OBD2 Del Sol ECU

[Brian]

if it was the 92-95 Del Sol DOHC VTEC it's the P30

[aust ek coupe]

so he would of had to have run a conversion harness for the p28. he says its 96-97 del sol si

[Brian]

if his is a 96-97 Del Sol, then yes

alright thanks for the help

[Brian]

no problem. I love answering questions about Honda's :mrgreen:

[aust ek coupe]

lol lmao i just thought something was fishy about it. i think is wrong with the ecu too

[Brian]

see if he will get a picture of the code on the side of it

[aust ek coupe]

he's only selling the p28 for $50

I gave away a socketed and chipped P28 when I sold my car, the buyer wanted to have the P30 JDM ecu for the B16 instead of the chipped/tuned P28. Meh.

[Brian]

great price for it.

[aust ek coupe]

a little cheap though thats why im thinking there is something wrong with it. and there would be no way i could check it cause my car is obd2

I was talking with my buddy and it's true. The 96-97 del Sol's came with a OBD2 P28. They are in no way like the OBD1 P28's. They can't be chipped or anything like that. They are just like a P2P.

Guess you learn something new everyday

[Spensman]

can or cant be chipped? we switched the ecu wires and plugged the vtec wires in just like there stated on diagrams he found but it was idling ruff and he was throwing a cel for the map sensor, you know if all the pins are the same for the 2 ecus a p2p and this p28

[Brian]

can't be chipped.

Pretty sure all OBD2a are the same pinouts. Not 100% positive though

I'll stick to OBD1 ECU's :yesnod:
