I got a 88 zc in a 90 civic. The ECU is the pm7 from an 89 teg. The distributor is from a 89 teg. The one with the j-spec engine was shot. My car cuts at 7100rpm, sometime lower. I have a cheap tach so I bought an autometer and it read the same thing. Why wont my car go to 7800 like it should. It's a big jolt when you think you can go higher but then the engine cuts. The zc dist didn't have an ignition capasitor but the 89 teg does, will this effect it? I want those extra 700-900 rpms!!!!!!
