Does anybody know if our computers keep track of how many times u flash them? I live in California and thinking of a egr Dpf delete with tune. But if the computer keeps track of flashes, I know they will fail u at the inspection.

 

From what I know... No. Here's info direct from a Ford Service Manager.


This is one of those "Good to know" pieces of info. At least it is for me and I thought it was worth sharing.

Ford has many dtc's that can not be pulled with the tunner. Have had mini maxx say no codes and pulled a long list of codes using the ford IDS. Reprogramming also leaves a string of "U" codes that are module to module comunication codes that can not be pulled with the mini maxx. Any time DTC's are cleared a P1000 will be there immediatly even if the H&S product isn't pulling it and remain there untill the PCM has ran long enough to clear it.

U0073 Control Module Communication Bus A Off
U0101 Lost Communication With Transmission Control Module (TCM)
U0121 Lost Communication With The Anti-lock Brake System (ABS) Control Module
U0137 Lost Communication With Trailer Brake Control (TBC) Module
U0151 Lost Communication With Restraints Control Module (RCM)
U0155 Lost Communication With Instrument Panel Cluster (IC) Control Module

These codes in general are ignored for general diagnotics unless it seems relevent to concern present. Multiple U codes generally happen when programing the PCM because it looses communication with the other modules during programing. But other things can cause these codes like low voltage where non essential modules shut down in low voltage conditions. Or high voltage where modules will shut down to protect it in high voltage situations. So a dead battery or a jump start could set U codes but would also be ignored if you are also seeing low or high voltage codes. Now if you are seeing only U codes with no other codes that would logically cause a U code then you start suspecting something else like a module reprogram from the likes of a the programmers that we are running.

Many codes are proprietory to ford software, meaning that only ford software can see these codes. Also the ford software can pull codes from specific modules not just the PCM and TCM like the H&S products. What it comes down to is unless you are going to put a vehicle back to stock and run it a 100+ miles, a dealer can tell if they look hard enough.

Pretty reliable info from a Ford employee.

 

Very good info!! That wouldnt be a concern at a state inspection since i doubt they have ford on site checking the codes. i have heard if the dealer suspects a tuner for such reasons like all the U codes, that they can retrieve a regen history. I don't know how long the memory is but the statement made to me was "if we only saw 1 regen in the last 1,000 miles it would tell us what we need to know". I'm not claiming this as fact, just what a reliable tech said to me. I had made the comment to him about programming a truck to stock and driving it a few days for a tuner to be undetectable.

 

That subject has been discussed on here a lot with no clear answer. It's mostly second or third hand info about how the dealer can find the codes. Seems like one of the teckkies on here said a regen or two would cover the tracks. I just figured the warranty was over when I did it. just not worth the stress of worring about it. Besides, we are on the road a lot far from home with the 5th wheel and if it fails on the road I wouldn't have a DPF with me to put on. Based on the posts on this forum most of the really bad things that happen to these trucks aren't gonna let you reinstall and drive through a couple regens anyway. The trucks going to the dealer on a tow truck hook.

 

By chance do you want to sell your DPF?
Thanks Darrell

 

Ill let u know once I find a suitable delete and program. I'm still trying to get my truck smoged and registered.
