Before Tunning
Ppl I need some help to find out what ECU do I have
Well I’ve done a DOHC ZC swap in my 89 CRX the original motor was a D16Z5 I’ve got a ZC motor with a PM7 ECU. I done a lot of searching trying to find out what kind of ECU that I have but all my founds shows a PM7 with different electronics components inside the ECU. Well all are a PM7 but there is a different in the last four digits like in PGMI page the ECU there is a PM7-E040, and a found other one with PM7-X030 the one which I have is a PM7-0000. So I’m wondering what the difference between all of these ECUs is. I believe if the electronics board are difference it also means the wirring diagram also will be different like there will be a variation between all of them Please some one take a look to my ECU and tell me which ECU it is and where can I find a wiring diagram for it As far for my swap, the car is running and I went for a driving test but when starting the car it run very rich and you can here the sound from a mile I got a wiring diagram from some one, the only thing that I could not found in my car is the IMA (idle Mixture Adjuster) sensor, do I really need this sensor, and if yes could some one show me a pic of it so I can go and search for it because I never seen one before My ECU: http://www.freeimghosting.com/galler...6392819641.jpg http://www.freeimghosting.com/galler...6392820414.jpg PM7 From PGMFI http://www.freeimghosting.com/galler...6392819634.jpg The Wiring Diagram I got http://www.freeimghosting.com/galler...6392336878.jpg |
