Dealership re-flash my PCM?

A friend told me that I should take my truck to the dealership and let him adjust my PCM for my bigger tires, and while he's in there, download any new "updates" for the PCM. Does this sound like a good idea? I'm thinking about getting a chip from Jody soon. Would he be doing the same thing(updates + correct tire size) in his custom burnt chip?

Re: Dealership re-flash my PCM?

The tire size calibration is in the abs module. But he can change the shift points to match the tire size in the programming.

Re: Dealership re-flash my PCM?

Is that you Jody?
Should I let the dealer do what my friend suggested? I mainly want my speedo, and odometer back to normal. Are there updates to my PCM's original burn?
Do your flashes increase the line pressure of the transmissions? And would you till recomend that Sonnax valve?

Re: Dealership re-flash my PCM?

The chip will over ride the PCM code. The tire size can be allowed for in the programming.

Controversial. Ford engineers determined that the original PCM program had a bug that needed fixin', so they fixed it. But the fix might cause other things to be different, too. From your viewpoint (not the Ford engineers) some updates are better than the old program. Some are not.

Not exactly. I think what Diane (Jody's better half) is saying is that he can optimise the way the engine runs and the tranny shift points, but not the speedo calibration. Because the speedo calibration is in the ABS module - not the PCM. So if you want an accurate odo or speedo, then have the dealer change the tire revs/mile in the ABS module.

If you're going to have Jody do a custom chip for you, then it doesn't really matter which PCM code he begins with. But he'll need to know that PCM code. So if the dealer re-flashes your PCM, be sure to get either the code or the new PCM part number so you can give it to Jody when you order your chip.

My Sierra Blanca (Spanish for White Mountain) in the sig pic was a great pickup for 11.5 years. I sold it several years ago. I drove a hand-me-down 2003 F-150 SuperCrew 4.6L 2V for a while, but it was unacceptable for towing more than a rowboat. Replacement is a 2012 F-150 EcoBoost SuperCrew Lariat that tows my 5,000-pound TT like a dream. Replaced the 2012 with a 2019 F-150 3.5L EcoBoost with max tow.
