handheld issues
has anyone had problems communicating with the ecu thru handheld,mines will not at all it was working fine then all sudden its not communicating with ecu,so i cant adjust anything or even read anything from dashboard,all grounds are good ive tried removing and cleaning cf card nothing seems to work,.....anybody had this problem?
I had problems with the handheld not responding and restarting itself over and over when my unit was new. I noticed it would do this after the engine had been running for a while. Turned out to be a bad ECU.
mine never has really acted right it seems like it had to relearn every time you started truck,i contacted fitech and sent in my controller,cable and ecu,havent herd back yet,will post when i know,what the problem was
