I just DE-computerized my 86 Bronco. I used an old manual choke Carter for the carb. I then did the GM HEI/ Ford Duraspark ignition. I trashed the ECM and all the wiring. The truck starts and runs AWESOME. The throttle response is great. My feedback carb and TFI ignition worked fine, but the difference now is night and day, not to mention it's a nice simple set up now.
