Hey guys, as it states I have a PR4 question. A buddy of mine got an ECU from a "tuner" from so-cal. It has a "mugen" chip in it and does not rev past 3k. Now he has a 87(i think) integra, with a d16a1 in it. Its a DOHC, and from what i gather it is the same as the DOHC ZC. So now I have his PR4 ECU and he wants me to burn him a new map. So here where the problem is. Does crome work for obd0 roms? what would be the BEST base map to start with? He has stage two cams, cause hes an ass, and NO other mods. Any help would be appreciated. Thanks in advance.
