Whats the difference between the two... other than the PG7 is an integra ECU and PM7 is the ZC ECU. I have a JDM ZC engine and am running a PG7 is this fine I do have 4 cel codes on
Codes 6 - Coolant temp, 7 - throttle angle, 9 - No1 cylinder position, and 10 - air intake temp

If I were to switch to a PM7 would it help any?

By the way car runs like **** wont rev past 2k and barely revs at all with backfiring

 

Fix the codes. They aren't cause of the ECU, they're cause you have sensors malfunctioning.

 

yeah, the ecu wont make a difference, just get all of the codes fixed, and you should be good. i used to have a zc, and ran that ecu, and it worked fine.

 

Ok well I started troubleshooting code 9 first - No1 cylinder position...

I changed the timng belt because it was loose probably skipped a tooh or something. No1 cylinder was full of oil and the gap on the spark plug had been smashed in so I regapped it since the plug looked fine. I then let the oil fall out of the cylinder. I checked resistance from the connector on the dizzy, that turned out fine. I went in the cabin and checked resistance on that side of the harness and I wasn't getting between 350-550, it read around 3009, weird to me. I think it may be that spark plug wire going to the No1 cylinder it was drenched in oil to begin with.

Any suggestions?
