Im wiring a obd0 to obd1 i bought a 88-91 obd1 dx harness it plugs up prefect...but when i when to put up my ecu it wont start....it feels like it wants to start but when i hit the gas it feels like it dies....i got a obd0 to obd1 ecu jumper...what do you change on the dx plugs so it will start....please help me...Tony

 

Have you already made the wiring changes to convert from DPFI to MPFI? What ecu are you using? What kind of motor did you drop in to your car?

 

yea...did you change the dizzy and 4 wire o2 and injectors and take out the resistor box, its not a simple plug and play with just using a differnet ecu and jumper. I doubt thats what you did...well i hoipe you didnt do that.

 

how do you change it to multi-point....i try to do it but im not sure...i drop a d15b jdm sohc vtec...im running a jdm chipped p08

 

i got a 4 wire 02 sensor its not on but i thought that it will work like that...i change everything to obd1...on the engine...will it run without the 02....

 

IM me if you need a harness built for your setup, I'll need your old core DX harness though.
