im trying to figure out what ecu i have... on the side it is a p30... and it is out of a 97 delsol.. b16a2, but what is weird is that it is 4 plugs wide and 3 pins high.. much like a obd2 computer. the obd2 harness plugs right in.. but when i search the p30computer it comes back as obd1 but with 3 plugs wide and only 2 pins high.. i am confused and any help would be great.. i want to know if this is a obd2 or a obd1... but how did it get the obd2 plugs??


thanks,

 

the p30 is an obd1 ecu, the connectors could have been resoldered to fit obd2 plugs, ive seen this service somewhere but cant remember. its done so there wont be a need for an adapter harness.

 

no i have the harness and everything.. its is all stock and has never been tampered with... and this is a usdm car if that helps?

 

there were two p30 ecus. one from the 94-95 del sol dohc vtec which is obd1 and 96-97 del sol dohc vtec which is obd2a. i currently have two obd1 p30 ecus, one is chipped with kenji racing chip and the other is stock. great ecus.

 

yup just like X was saying there are 2 versoins of trhe p30 ecu OBD1 and OBD2a ...I ran the JDM OBD-1 ecu on my b16a swap and liked it very much.
