PR4 ECU on my DOHC ZC??
A buddy gave me this ECU with a bunch of parts the other week. I was told by him that it is A PR4 ECU (also says so on the sticker on the side). Also told me that it has been chipped and will work on my DOHC non vetec ZC. He had no use for it since he is going with a VETEC motor now. I've been looking around and have found that most people either run the PM7 or PG7 with a ZC swap. Will this ECU that I have acually work for me?

pr4 ecu will run rich, also redline is cutdown to 6800/7000rpms..
I have run the pr4, pg7,pm7,pm6,and custom
the pg7 is high redline, better fuel & timing curve, no speed cut like the pm7..
the pm7 ecu was rated for that motor, so perfect idle, and fueling/timing maps.
I can re-chip that pr4 ecu, with a pm7 bin if you wish pm me for details..
