All Honda ECUs have a part number which is located on the side of the ECU and inside the ECU on the connector. e.g. 37820-P72-A01

The part number consists of three components:

-Honda's part number for ECU, which is always
37820
-Three characters (which are loosely related to
the model of car/engine). e.g P72
-Three characters (which are the revision of the
ECU) e.g. A01

i need a p30 from the 92-95 odb1 delsol DOHC vtec si/eg sir for my b16a then right? instead of the p28 i have

[Beyond Imagination]

yes because the p28 is a sohc vtec and the p30 is a dohc vtec. maybe that's the problem why your car isn't running like it should.

[salchichon20]

see this is what im telling this guy... any ways thanks for the help i really appreciate it

[jcrx]

Yea, that guy is an idiot, the P28 is for the 1.6 D16Z6's.

hey salchichon20 u still have the p28 ecu? cuz im looking for one

[salchichon20]

yeah i still have it

[HondaOz]

i have a question, ive been doing some research, and with the budget i have, it seems that the 1.6L DOHC NONE VTEC!!!!! is the best choice, i found out that my 91 hb is easy to do that swap in it, but if i want to go with b16, or b18, i gotta get special mounts, and there is also some wiring and welding, cutting ect that i have to do, anyways.... what is ur opinion on this?

[HondaOz]

i meant the ZC
