Stating that you even know what they’re referencing when they say something about a “flash counter” is pretty indicative that foul play went on and they’ll dig to figure out what. It’s best to act completely aloof. The average layman doesn’t know anything about flashing firmware or an OBDII port.
We shouldn’t act as though we know more about the computers in GM’s car than them. There’s a chance something could go wrong with a 100% stock car. If you’re going to start flashing then in all likelihood, even if it’s not by much, the chance for failure may increase, and yes GM will use the catchall of the vehicle not being designed for whatever modification you did and hence voiding of the warranty. Instead of trying to beat the system, it may be well worth the time and effort to find mod-friendly dealers and service centers, because they do exist. Sent from my iPhone using Tapatalk Pro |

If you mod and tune your car you should assume the parts affected won’t be covered under warranty any longer.
People can claim the mag moss act till they’re blue in the face. It doesn’t cover aftermarket parts/tunes. If the dealership shows GM that the car is tuned, GM will deny your warranty claim in 99% of cases. Don’t believe me? Ask the guy who got his warranty denied over a catch can on a KNOWN ISSUE WITH THE OIL PUMP when the dealership started and then grenaded the motor when they were told the oil pump wasn’t working. While a pretty out there example, stuff like that does happen. Is it bullshit? Yep. Is it easy to fight GM over something like that? Nope. You got to pay to play. I personally believe you shouldn’t race/tune something you can’t afford to set on fire and push off a cliff. That mentality has served me well so far. Just my .02

I believe the ECMs are vin matched to the car these days.
I wonder if the tuner companies can be held accountable if they state that the flash counter isn't activated and GM voids repair because it was? That would be an interesting case. I have always believed that if warranty is important, then leave the car as it came from the factory, in every way. At least for the first couple of years. Give the factory gremlins time to show themselves before doing anything that would give GM a chance to get off the hook. I don't know exactly what the price tag of replacing an LT1 would be, but I'm guessing very close to if not $10K or more. |

It's a tried and true solution that's been around for a while. New ECM's are $90 at Amazon, not bad at all. Quote:

By vin matched, I didn't mean that the dealership would read a different number, but that the other systems in the car would not handshake with an ECM without the correct vin. Just something I read awhile back ago, maybe I misunderstood it.

Identifying Aftermarket Calibrations before Warranty Repairs
Quote:
-------- Just reflashing the factory tune after engine failure will NOT work. When the tech sends screenshots to TAC, they compare stored values. If any parameter is out of spec (max rpm, etc.) with their stock calibration values, bye bye warranty. You're gonna need to reinstall the original ECM to provide acceptable stored engine operating parameters, since a failed engine won't run to create new acceptable to GM values. So, it's not just about the tune, it's about the values stored by operating a tuned engine, even if the stock tune is back in place. http://sandyblogs.com/techlink/?p=4248 - Identifying Aftermarket Calibrations before Warranty Repairs Quote:

I spun two main bearings. There were no codes associated with that failure.

I think the whole thing has a lot of unknowns like your point (MrChrisLS3) of where's the operating parameters (stored in nvram) that would signal an engine failure? Do they check that? Is there a date and time stamp on the data that will tip them off to the ecm being recently re-installed after engine failure? Or, do they just scan for operating parameters outside the acceptable range with the factory tune? They're a lot fancier than anyone really understands. Tuners are saying just reflash the factory tune - So Wrong! Tune at your own risk, and be ready to fight GM in arbitration, make them prove it. Oh ya, tuning is also illegal for anything except off-road use. n

The only indication was zero oil pressure and after shuting down the engine would not turn over. When I brought the car in I explained what happened. They tore into the motor and didnt find a problem untill they worked on it for a few days. I didnt get an impression that they pulled any kind of data from the ECU. Also this place doesnt see cars like this. Mostly trucks and econo cars. Maybe they are oblivious to the aftermarket. This place was old and thr service manager used a flip phone.

-------------- You lucked out alright, they're required to send full data per GM procedure. Lucky GM didn't kick the warranty claim back. They could back-charge the dealer after a dealer audit, but it's probably not enforced very well. Quote:

I have a tune from them & a few months later I went in for service and got a new engine and transmision covered under warranty. They might give you a tune along with some bolt-ons and say you're still covered but your local dealer won't say you're covered. |
