I am new to the forum here but have been reading alot of information that has helped me with my 1999.5 F350 7.3 PS. Thanks, this is a great forum!
I noted that you mention cycling ignition 8 times to reset computer, does that give you a complete reset to the factory tune and could it mess the computer up?
The reason I ask is because I have a Predator tuner for my truck and it started being difficult to change tunes. It acted as though the tuner could not communicate with the truck occasionally. It finally got to the point that I was stuck in a tune and could not change it. I sent the tuner back to Diablosport and they repaired an internal wiring problem and returned it to me. I immediately tried it on the truck and it still would not work. Their tech guy talked me through a force method to try and reinstall the original factory tune to no avail.
I thought that it could have been a problem with my ignition switch so I cycled it about 10 times and then attempted to restore the original tune to the truck. It acted as though the original tune was being reinstalled and then halfway through the process the tuner stopped. THEN MY TRUCK WOULD NOT START AT ALL!!!!
Long story short: trip to the dealer and they said the PCM was bad and replaced it, flashing the original program back in. Truck runs great now. Diablosport took my tuner back in for the second time to test and now they tell me that they are giving me a new tuner.
Could I have messed something up by cycling the ignition? Would you all guess that the PCM was just going bad since I had communication troubles? Or should I believe that the tuner went bad and screwed my computer up?
Alot of questions for a first time post, but this has been a very frustrating and expensive ordeal!
Thanks in advance!
