Still learning new stuff!

[Power Hungry]

Ok. So I've been at this game for almost 24 years now. Ford tuning has been just been a living, but it has been life for me. I never stop poking around, trying different things, or looking at things from new angles. Well, this past Thursday was another one of those "lightbulb" days for me. It proves the old adage that you can learn something new every day if you pay attention.

At the behest of a customer, I was looking (AGAIN) for a way to turn off specific DTCs for sensors that had been removed. In this case, it was DTCs related to EBPV (Backpressure Valve) and AIH (Air Intake Heater). Now, I've been able to circumvent the AIH codes by changing the self test parameters, but I've not been able to successfully eliminate some of the DTCs related to removing the Backpressure Pedestal. We've just told people to leave the solenoid plugged in and forget about it. The only other option we had was to eliminate ALL DTCs by setting the number of allowable DTCs that the PCM could store to zero. This means that the PCM would never set any codes at all, even if there was a legitimate problem. This is never a good idea and I figured that there had to be a better way.

So I sat down in front of the computer, opened up a binary file, and started digging around. Switching gears from the way I have historically handled DTC management, I stumbled upon a solution where I can eliminate ANY single, specific DTC! I couldn't believe it until I programmed a couple test files onto a Hydra and stuck it in a PCM. Instantly, the specified DTCs were gone!

As I said, this is something I've been trying to figure out for over 20 years, and the answer was staring me in the face the whole time. I just didn't understand what or where it was. It pays to stop, take a break, clear your mind, and look at things a different way. You never know what you might discover!

Anyway, we can now permanently eliminate ANY DTC you may have. We'll be updating the definitions for our preferred custom tuning dealers and then roll out the updates to the rest of our Minotaur users as quickly as possible.

If you have any questions about this, please let us know.

Take care and God bless.
