so i have heard that if you are running a pr3 (jdm obd1 b16 ecu ) with a GSR motor that you have to run a different dizzy, and run a 2 oxygen sensor setup ? is this always the case?

bc im running a obd1 JDM GSR with a LS dizzy, i had cut off the one leg to make it work ( its hella ghetto i know. but im broke ), ( skunk 2 mani. so im not worried about contolling the secondaries like a GSR manifold ) and will be running a PR3 from a obd1 jdm b16 since my chipped p28 went bad.and am still using a single oxygen sensor on my header. am i gonna be running into problems with this setup ?

 

oh and the car is a 94 integra RS . dont know id that makes a difference.

 

Pr3 is obd0 b16 ecu. Yes it does want 2 o2 sensors, but if you get a chipped pw0 or pr3 then you can disable one of them and only use one and be fine.

EDIT: I forgot there was a pr3 that did the Integra RSi/XSi that is obd1, :-(, you'll have conflict with the o2 sensors though.

 

i have heard that the obd1 pr3, and the obd1 p30 are basically the same exact ECU except the pr3 has more agressive ignition/ fuel maps. ? can someone verify this? if so then why would there be conflict with the pr3. when i know a few people who have run the p30 in an obd1 car/setup, and had no problems with just the single 2 wire oxygen sensor on the header?

 

p30 is stocked for one o2 sensor, pr3 for two.

hmm. well, that sucks. looks like ill be wiring in another o2 sensor. anyone know of a way to do that ( like from the cat. or anything ? ) ? or how is it possible to somehow eliminate the secondary w/o having it chipped?
