I was wondering if there is a way to reprogram my PCM on my 2012 Impala. I have checked all over the internet and there are no programmers available for any v6 2006-2012 Impala. Mainly to get rid of the low speed limiter of 112. Any Help would be appreciated.

check trifecta performance the 2010 thru 2012 3.6 camaro guys seem to like them the most. Also IPF does a tune but the car has to be there for them to do it, in AZ.
Also check to make sure this does not void your warranty. You could buy a new pcm have that tuned,then if you need warranty work swap the pcm out.

If you were using something like HP Tuners, couldn't you just re-write the stock fine back to your PCM? Wouldn't the dealership (using a Tech II presumably) just see something like "lost communication with ECM" (which can be explained as a battery change, jump start, whatever)? Or, does this operating system have some sort of additional logging capacity?

That's presuming anyone has or is able to change the PCM file on these 2012+ Impalas period. I haven't seen anyone who's done this yet.

if you get your computer flashed it will void your warranty.

Some guys can make the tunes undetected by a gm tech2 scantool.
But they can send a "picture" out to gm and gm can tell them the last 10 programs flashed to that ecu.

Now they arent gonna do that everytime and the only 2 cars they are really worried about are the turbo`d regals and the camaro but just wanted to goce you guys a heads up on that new system they have.

I guess the only way around it is to keep the factory computers and get different ones flashed then when it cones time for warranty work just swap the factory ones back in.

Very weird- not sure how that works. I know that 2011+ Mustang guys have been going through fits with Ford denying warranty claims after tunes have been installed. Not sure how often this has happened with recent GM products.

I also do agree that most dealerships aren't going to check on Impalas for PCM changes, especially if they're stock looking. I'd imagine this would be a bigger problem for Corvettes/Camaros/etc

Why are they throwing fits? They knew what they were doing when they got the tunes. You either decide to take a calculated risk or not. Personally, I took the risk and fully expect if I have a major engine issue or turbo issue in my MKS, it will be on my dime. I intentionally did NOT take such a risk on my 09SS, as the probablity of a tranny failure was high, and felt the odds were not in my favor to risk losing the warranty.

But in all fairness, the CTS-V folks and Vette guys whine too. No idea why, and I am not trying to sound like a d*ck, but the SHO/MKS guys all seem to understand the drill and you need to expect a warranty denial if you get a tune. And, we don't even pretend that we think it is unfair.

To keep it real brief...they were probably spoiled by the previous model (with the 3V engine - like mine). It was pretty bulletproof with a basic tune and bolt-ons installed. Ford never really cared about tunes and there wasn't a history of warranty issues with tunes installed.

The 5.0L (particularly the first 2011 run) seemed to be popping the #8 piston left and right after a tune was installed- Ford caught wind of this and started denying everyones claims. The upset folks argument was that as a Mustang, with a huge aftermarket, performance following, and history of being drag raced, it should hold up to a basic tune. Ford obviously didn't buy their arguments.

I wouldn't buy it either. Ford set the car at such a level on purpose to minimize failures and warranty claims. Can/should the cars be able to handle more? Probably, but so what. The bean counters set the threshold acceptable level to them, and the cars were purchased at that level.


p.s. Also thank you for the explanation, it does make some sense, though the logic is still flawed....it does however, explain why they thought they could get away with something they knew could void the warranty.

No problem. I love that MKS.

I guess it jusr depends on the person.
Usually it goes intake and catback will keep your warranty
anything else will void it.
