I'm new to this forum, hello

I am considering buying an 06' f150 supercrew with 5.4L. Just wondering if I reprogramme the computer... will a technician know?? That is If I reprogramme to stock before service; does the programmer leave any kind of evidence of reprogramming?

Thanks

 

Some say yes.

Some say no.

I do know that if you plan to take it to the dealer, you should remove the program at least a week before to allow for the truck to reprogram itself, and go through a drive cycle.

I don't worry about it for my truck. My dealer is pretty good about mods and doesn't blame a mod on something unrelated.

But if you fry the PCM, plan on paying out the bucks. And with what little I know about computers, I figure it doesn't take the brightest Tech to figure out that the PCM has been reprogramed.

Every computer leaves tiny little footprints.

Most of the people who have had a problem with their tuner, have had the PCM repaired, reflashed or replaced by the tuner company.

So I don't worry about it.

Good luck.

 

I have read in previous TP’s posts that the dealerships can’t tell using the WDS but supposedly, Ford factory techs could with the diagnostic equipment they have

 

There is a 7 start memory,do 7 starts and unhook the battery.

 

Really? So to clear the "cache" you would do 7 individual starts, then remove the battery for 2-4 min?

 

I think you disconnect the battery for a few minutes, then do the 7 starts.
