Hey guys, this year and the end of last year, I've been having issues with the car running great on track then suddenly losing all power (like someone shut the car off) for anywhere from a fraction of a second to as much as 4 seconds. This is quite frustrating to say the least. We've relocated the TFI module to the inside of the fender to get it farther away from the engine and higher heat areas. It doesnt seem to have made any difference. I should also add that during this time of having issues with the TFI module, we converted our foxbody mustang over to Mass Air Flow. No issues for the prior 13 years of racing when we had the speed density computer system. We are running the wiring that was in the car back to 1986.
Yesterday during the CMC championship race, another Rocky Mountain CMC driver in a Mustang also had his TFI module fail, causing a complete ignition failure and thus causing him to not be able to compete after running in the front. He completely rewired his car so no original wiring.
Have any of the Mustangs in Texas region have this issue? Is there somewhere where we should start investigating this issue? We've run TFI modules as far back as the 80s, run some that are "new" and they all will fail at some point. Could this be heat related?
Any help or guidance on diagnosing would be appreciated.
