how's it goin'? im new here and have a question for you. I recently bought a 91 dx hatch with a 92-95 Si SOHC VTEC motor in it. I converted the stock DPFI dx harness to a MPFI harness. I have switched the map sensor wires to read correctly. I am also running a 91 civic Si ECU (PM6) to work with the new MPFI motor. It runs real good idling, but it hits off the rev limiter at 3300 rpms. Does anyone know why it may be doing this?? I just can't figure it out by myself. ANY ideas are appreciated. Thanks.

Also, where is the EACV? any pics? Thanks again. I tried a search first but could not find an answer to my particular problem.

 

sounds like your distributor is screwed. Maybe the distro itself or at least the wiring.

 

Both the dx and si distributors work with no difference. what could be wrong in the wiring dept.? thanks.

 

anyone???

 

the dx dizzy is different form the si.. if the problem is the same i would say its your dizzy.. what ecu do you have??? and when you said switched the map wires did you mean tps??? any cels???

Yes, I meant that I had already switched the TPS wires, not the Map. What dizzy do i need? It runs with the pre-obd dx dizzy and the obd1 dizzy that came with the motor. I am running a PM6 ecu. Do i need to get a 91 SI dizzy. what else could be wrong?
