is the b16a3 motor an odb1 motor? or is it odb2? along with that, is the p30 an odb2 ecu? or odb1?

its an obd1 motor from 94-95 del sol vtec model. the p30 ecu that comes with it is obd 1.

em1gangsta

thanks, cuz i tried the odb2-1 but it didnt work. my car is going mental on me. so im guessing ima have to go from odb2b-odb2a. the gsr ecu right? if i do that, will i still some sort of result?

sal35dm

i don't understand. what kinda of car are u trying to put the motor in? are u trying to put a b16a3 with a p30 ecu in a an obd2b integra? with an obd2b wiring harness?

no i have a 00 si, and i tried jst putting a chipping a p28 and putting it in my si, and it backfired. i did this cuz my friend with a b16a3 said that it would be fine if i did that. u didt realize that his motor was odb1. i thot it was odb2, so i tried it. well now that i know it wont work, because youi cannot put an odb1 ecu i an odb2 motor. so i was thinknig about putting a gsr ecu in my si since its odb2.

Horseofcourse

how could mix and match them like that? There is no way to plug and play the different OBD's without conversion harness's....

wait, what??? the 99-01 ecu, aka SI ecu is an obd2B ecu and the GSR ecu is an ODB2a ecu, and they do make a conversion harness for the swap.

OBD2 ecu's can be either obd2a or obd2b. The OBD2a ecu's came in 96-98(correct me if im wrong) and the OBD2b came in 99-01(correct me if Im wrong again). They do make conversion harness's for that.

em1gangsta

no, your correct. im going to have to do that swap with my ecu because the odb1 swap messed up my car. now i jst need to find a GSR ecu
