I just got a hondata set up and trying to start my car, but when i do, it starts better in open loop then it does in closed loop? But the car runs very rich in open loop and back fires every couple of minutes but it runs smoothly but when its in closed loop it hesitates and jerks when i give it part throttle
::setup::
s200 p28
720cc injectors
FP-52 psi

 

anybody

 

just sounds like you need more tuning in your closed loop setup. I beleive youll be fine, as far as I know, closed loop is for saving gas anyway. correct me if im wrong.

So i would say that you have some tuning issues...or possibly one of your sensors is malfunctioning...its not necessarily bad but your gas milage will be
