2014+ Engine & Transmission Tuning

[Full Lock]

I'm having a hard time not ordering a BBT Auto-Cal. Think I'm going to pick up a intake see if I like it, then go with a tune.

Yes, we moved from VA to CA.

 

To answer the question on detection: with the current methods GM uses to detect aftermarket tuning, so long as your vehicle is returned to stock tuning, there should be no issues. The Global A vehicles to have nuances in place by GM, but there are ways around that as well.

Can anyone else confirm this? I thought the dealer/GM could tell if it was flashed.

I would be interested to see this tested as well, both HPT and EFI have said GM will see if the ECM/TCM has been tuned even if back to stock as the flash counter will be tripped.

i am waiting also to confirm they can not detect it ,it is killing me the wait ,trying to be patient

There are ways to get around it, for instance one handheld on the market writes bad data to the end of a tune, to screw with detection. Vast majority of people will not be able to get around it though. Regardless, GM claiming a warranty block is not the end of story, generally they will not put up a strong case in arbitration/mediation.

You would think with all the bad press these days GM wouldn't bother someone over a mild tune. To get the funky out of the trans, and to dial out the V4 till after 60 MPH would put a smile on a lot of faces. I don't care what kind of exhaust you have the V4 sucks. Its the truck crazy people who talk and join clubs anyway keep them happy and the word spreads. All the money GM, Ford and Dodge spend in motor sports so we buy their stuff, then tell us we cant do a few mods that's crazy as hell.

If GM is so inclined to put AFM on all the trucks, at least let us decided from the factory if It is turned on or off. The new Vettes have selectable AFM, and I think the Ram trucks do as well with the ECO button inside the cab.

That would work

Is it possible to just do a TCM tune? I'm ok with the engine performance for the most part but the shift points and overall operation of the transmission lacks a lot to be desired in my book.

If you're gonna do one, why not do both.

That's awesome and thanks for the info. You'll be hearing from me very soon.

Arbitration with GM sounds like a guaranteed loss for the owner. So it is completely undetectable to GM or just not obvious without significant digging?

[chuckwi11]

Performance tuning is not something new... bottom line is it IS detectable by the service tech if they know what to look for. The Magnuson Moss Act protects the consumer with respect to warranty repair. It is the responsibility of the dealer or GM to prove that the modification you have performed resulted in the failure you are presenting. If you get a tune and you have an engine or drivetrain failure that can be linked to the tune then you will not enjoy repair under the factory warranty.

 

If the warranty concerns you, don't get a tune. If the you are concerned that the tune is visible to the service tech, don't get a tune.

 

If you are worried and you still are questioning it then I would suggest that you talk to your service tech and see what they say about performance tuning. He or she is your first line of defense or your first line of battle. I have always tried to have a good relationship with my service tech and always know where I stand when I do modifications or upfitting.

 

Arbitration with GM over a modification is not cut and dry in their favor... however if you install a hardwired radar detector or aftermarket lighting or plug, pour or attach anything in to your vehicle that damages the vehicle you stand the chance of having to go through the process.

I searched this thread as well as the forum and not going to lie did not want to read through 25 pages of posts as I just joined the forums. Have the 4.3l v6 and was wondering if any tuning options have come out or will be coming out?
