Posted: Thu Apr 22, 2010 9:19 pmwell i guess first off would be converting it to OBD1 if you haven't already
Posted: Thu Apr 22, 2010 9:41 pmwell it is obd1 but he wants to go to obd2 to pass NJ inspection cuz its a 99 teg would a ctr ecu work
Posted: Fri Apr 23, 2010 1:00 pmuse the ls ecu... i had a 94 teg and ran my b20 off the stock p75 and it ran fine... it should work to pass your emissions, id use the ls comp over the ctr for that engine...

gsr ecu will run a stock b20 very badly. The fuel/spark maps are totally different. The LS ECU doesn't look for vtec so wont be throwing a code. It also has correct spark/fuel maps and runs amazing. I pulled a B16 and dropped a JDM 99spec b20b in its place, same wiring harness everything, put in an obd2b to obd1 adapter and a obd1 p75 ls ecu and it ran perfectly. It would push you back into your seat, it's awesome. <3 B20's
OBD 2 ecu's wont plug into an OBD1 car, they also dont make adapters to go that route, you can go FROM OBD2a(96-98) or OBD2b(99-01) to OBD1(90-95). Never the other way around.

x2 LS ecu will not throw a light on a b20 for vtec... as an ls is not a factory vtec engine...
