we have replaced my usdm h23a1 with a euro h23a vtec and the car runs fine with the original obd1 p14 ecu but it is throwing a knock sensor code, i would like to know what ecu to use so that i have vtec and what wiring to change. i have already rewired it for vtec and the jdm p13 ecu willnot even start the car. we put the right injectors in and are at a stand point. the car has to stay obd1

 

sweet deal i was gonna do this but i decided to just rebuild my h22
