i have a 91 integra with a 97 gsr right now the harness is obdo what ecu do i use or do i need to change my wireing harness and components

[street dreams]

your going to need a pr3 b16 ecu and i hope u have a skunk2 intake manifold or your going to have problems w/ the gsr

[bunday88]

pr3 is that gunna be obdo? or somthing i need a jumper harness for

i disagree. b16 obd 0 ecu (or any b16 ecu) is poor match for a gsr engine. because of the intake air bypass system in the gsr manifold the ecu is set to switch to vtec at 4500 (too low for a b16) and then the ignition timing goes down until the AIBs open up at 5700 and then the timing starts ramping up quickly. b16 on a gsr (w or w/o stock gsr manifold) ecu yeilds a big bog until nearly 6k rpm because of this. you should consider switching to obd 1 and getting a chipped or stock ecu. if your gsr engine has the stock intake manifold and it's all functional, then you need to have iab added to the ecu or find a p72. if you have more questions, check out the website or email me. I likely won't check this thread again. tim
