I have a pg7 ecu supposidly from a `88 integra for my zc motor. I know the zc works because it fires up on a `88 si ecu (pm6) from the junkyard. It says pg7 right on the thing. When I put it in and try to start the motor it feels like it wants to start for 1/2 sec but does nothing else, the light on it comes on like normal and all. It is the smaller case style too, I cannot find a picture on the net anywhere of it including pgmfi.org. I heard there was an earlier version of this ecu? the serial# on it is 37820-pg7-6640 ohh its an oki ecu too if that helps.
