Will a Black Bear Tune Void My Warranty???

[high country]

Youre exactly correct. However, if a tune is only to optimize shift points and responsiveness I dont think that should void a warranty but it can. A good tune wont run beyond the vehicles capabilities. A tune may accelerate the wearing out of components or expose a weak spot in design quicker. But overall, people arent going to be running their daily driven vehicle on its ragged edge often enough for the tune to be the cause of any failure. But when you get a tune, that gamble of losing warranty is one you take.

Or GM has tuned the vehicle to the maximum of the parts they used to build it, any more and it's more than it can handle and it will break. The days of spending profit to increase durability are long gone now that they can manage breakdowns with a program.

Manufacturers leave tons of safe power untapped. If they didn't, tuners wouldn't exist.

Tuners exist because the tuner company's make money on them and don't care if you blow up or have warranty problems on your vehicle.

Not aware of a single member here with a bad tune from a respected supplier.

Didn't say anything about a bad tune. All tunes in general put the vehicle at conditions that the vehicle is not designed to operate.

Whatever. My 2011 was tuned and I wouldn't hesitate to do it again.

And no one has ever had a problem with a 4l65e, like I said tuned down to prevent breakage.

I have a Black Bear tune. Here's my latest diagnostics report. No problems. I wonder what the difference is?

mine stays plugged into the vehicles diagnostic plug, Does yours?

[bigsam94]

I want an official answer from the Black Bear people. My last truck I had 1 ECM that was tuned and 1 ECM that was stock and I could swap between them if need be but I never had to. All the years of getting service one my truck and NO ONE ever said anything to me about the tune. It was a 2007 Sierra and I had it 7 years up to my 2014.

 

 

This is what they told me. Sorry i still cant figure out how to post images directly.

Trying to figure this out.....

 

GM can give a very detailed step by step to find out if a vehicle has/had a tune on it, but can't figure out what is causing the shaking or vibrations on some of their vehicles?

These kinds of threads are so full of opinion. The facts are no one on this forum for a 2014/2015 has been denied warranty due to a tuner, and employees of GM have tested multiple handhelds and reported no flash counter changes when using one such as Diablosport.

 

Enough of the opinions about what you think GM can or cannot do. Search the topic, it has been beaten like a dead horse and members have proven that some handhelds cannot be seen by GM via the flash counter.

I dont agree with either of these statements. Why would ANY manufacturer tune a vehicle to he maximum potential of its parts? Thats just asking for parts to break because each time the vehicle is driven its being pushed to its limits. Manufacturers would be warrantying whole engines, transmissions, transfer cases, differentials etc. round the clock. In the end it would be grounds for a huge liability lawsuit and the manufacturer would be bankrupt.

 

Also tunes that just optimize performance. You talking about adjusting timing, fuel charts, air ratios, etc. If you look at some manufacturers like toyota, the dealer will install a supercharger and warranty the vehicle completely. The SC will increase the workload on the engine far more than just a tune and no external power adders. So, youre telling me that toyota is installing and warrantying these parts knowing full well the vehicle will not be able to handle the forced induction? I seriously doubt it.

I guess some people don't understand how GM's torque management works, my 6.2 makes 420 HP and if you have ever watched it the HP and torque fall way off due to the TM removing a bunch of timing at the shift point. This is done so the transmission can live a long happy life, remove the TM and get full torque and HP at the shifts and the truck drives like a dream as it slowly self destructs. This is what I meant when I made my statement below.

Getting back to the op's question, no the tune will not automatically void the warranty but GM can if they find it and decide they want to void it and you won't have a leg to stand on. They are going at this in courts as a theft of propriety software and can even bring charges up against you for it.

There are several tune threads so I forget where I posted it but your blanket statement is dead wrong. A member here had a engine failure that was clearly unrelated to the tune but GM initially denied it. He fought it, with Blackbear and won. GM and other makers do NOT tune to the absolute limit. They tune to the point of their archaic, absurd internal standards. Read some of Bob Lutz' books if you want to know more about the absurdity he encountered when he came on at GM.
