If he wants to tackle the GTX ECU then more power to him. You have to find someone selling the GTX ECU and harness and you can have it running like stock from there. Its not an easy job since I have attempted it myself.

Use a protege SOHC or DOHC wiring ......years 90-94 ...available at any good scrap yard...thats what I did.....

20 000km, no problems.......550km/tank on the highway, 450km in town......

converting obd2 to obd1 is a heck of a job

Is there any place that can re-program my ECU(94 MX3 DOHC) to use it with the BPT engine?
