Ok so I got a dohc zc in my Rex and the ecu is a pr4 should work right? Well it does not work right because if u just punch the gas it dies but if u roll through the gas nice and easy it revs fine and it seems like it's cutting out at low rpms

I replaced the tps checked the plugs put more grounds on the batt. O and it seems to work fine when the car is cold but after 15 min it runs like crap
Help please

 

Actually the PR4 is for a 1.8 b18 LS motor and you need a 1.6 (pm6 si ) or better yet PG7 (89 integra 1.6 dohc d16a1) or the real ecu is the PM7 JDM (hard to get tho). Ive run my zc with a pr4 but it was so rich gas would come out the tailpipe. Pm6 works fine for me it does a little better on gas(/smog)

 

I have a pm6 5spd ecu for sale if you need one

$45 shipped

 

ok im so this ecu will fix my problems and pm me for your information cuz i think ill buy the ecu you from you
