i just finished my swap..well not finished...but its in...i used 99 Gsr harness-on JDM ITR in my 00' integra LS

start the car with STOCK(p75)ecu..car runs/revs/moves perfect..except it idles at 2 grand...i recalibrated the TPS sensor like i was told...and it still idles that high...throwing code 10 also(IAT sensor)

so i figured i'd try and see how it ran with my JDMshit obd2b-obd1 jumper harness and my skunk2 chipped p28..and the car runs like ****...if i unplug #2 injector the car doesn't change at all...so i jumped #2 injector in with number #1 injector..and car runs fine...idles at 700 like its suppose to....doesn't throw any codes!

plug in a obd1 p72 ecu see if that helps any...car idles and revs perfect...but my tach when revving stops at 5 grand and then bounces back to 1000 and back to where it is revving down..doesn't throw any codes either....and get this...there is no rev limitor on this STOCK p72...does that have something to do with the tach not working?

WTF is wrong with this?

 

ha ha thats funny. sorry about your luck. that sucks. why didnt you use the ls harness and add vtec? sounds liek thre are a clusterfuck of wires. did the harness come from a junkyard? maybe they pinch ed a few wires or something.
