Warranty Voided Is You Tune Your New Truck?

noupf · April 12, 2010

Just curious is getting a blackbear tune or one of the handheld programmers will void my factory warranty on my 2010 Silverado. I want to get rid of the AFM and get a little more power from my baby.......

Thanks guys !

It sure will void it...if you bring it in with the tune still in.

Blackbear may be able to get you a new set of modules you could just swap out...not sure on the availability of them though.

Hand held can switch back to factory tune before you go in. I have heard talks that they can tell if it was tuned even if the tune is returned to stock...But I think that's BS

It will void it period, even if you remove the tune. The ECU keeps a record of the fact that it has been reprogrammed and dealers are required to retrieve this data as part of the warranty process. So tune = no warranty period.

If you flash the system back to stock all they can see is the last tune written as being the original one. Now to do that you need a handheld. The Blackbear route works fine on the ECM but since the TCM is part of the transmissions valve body you are not swapping that anymore. You don't have to tune the tranny I suppose but since shifting is one of these trucks biggest problems I wouldn't not tune it.

Now you may not have to do this every time you take the truck in of course but if for whatever reason they felt like checking and found an aftermarket calibration in the ECM ( they have a bulletin how to do it) your powertrain warranty is gone. If you really feel like fighting it and you are in the USA there is the Magnusson Morrisson act, but that is meaningless to me as I am in Canada.

I was not impressed with the performance of the 6.2 in stock form( on 4 trucks it was very dismal at best) and didn't want to fight with this tuning and maybe get away with it crap. I am not confident in the 6 speed myself and since I see it as one of the biggest things I dislike I just left the truck on the lot. I daily drive a 6L90E and it has issues...... but of course GM says its "okay". I live by the if you can't afford to pay you can't afford to play analogy. That being said in this instance the trucks in no way made me want to pay anything for them so the decision was easy.

Most guys will tell you to just do it and you will be fine. Probably....... unless you have a dealer that decides to check for whatever reason, or eventually will be forced too. It's up to you.

From what I have read on BlackBear site, only the Diesels have the ability to verify if a tune was done.

The Gas engines do not leave a "track record" if you go back to OEM tune.

Gas Powered Engines Only

Models: 2006–2009 GM Passenger Cars and Light Duty Trucks

2006–2009 HUMMER H2, H3

Excluding Pontiac Vibe, G8, Chevrolet Aveo, All Saturn and Saab Models

Important: This bulletin applies to Gas Powered Engines ONLY. For Diesel Powered Engines, refer to Service Bulletin #08-06-04-006A.

If a suspicious hard part failure is observed in the engine, transmission, transfer case or driveline, perform the calibration verification described to determine if a non-GM issued engine calibration is installed. Non-GM issued engine calibrations subject driveline components to stresses different than the calibrations which these components were validated to. Repairs to transmission, transfer case and/or other driveline components where a non-GM engine calibration has been verified are not covered under the terms of the New Vehicle Warranty.

Instructions for Confirming Calibration Verification Number (CVN):

1. Go to TIS2WEB

2. Select "Calibration Information (SPS Info)"

3. Enter VIN

4. Select "Get Cal ID"

5. Select "ECM Engine Control Module"

6. Select "Next"

7. Select "Complete History"

8. Print

9. Take the printout to the vehicle along with the Tech 2®

10. Plug in the Tech 2®

11. Go to diagnostics and build the vehicle

12. Select "Powertrain"

13. Select "Engine"

14. *Select "Engine Control Module" or "PCM"

15. *Select "Module ID Information" or "I/M Information System" if module ID information selection is not available.

16. *If "I/M information System" was selected in step 15, it may be necessary to select "Vehicle Information" in order to display the calibration information.

17. Compare the calibration ID and Calibration Verification Numbers (CVN) to the Calibration Verification Numbers (CVN) on the printout.

* Steps may vary by controller.

Although the part numbers will be the same for each, it's the CVN that will determine if the calibration is GM issued. If ALL of the CVN's are EXACTLY the same, the calibration is GM issued.

If the part numbers match and ANY CVN's DO NOT match the printout, it is likely that a non-GM certified calibration has been installed.

If the CVN information is displayed as "N/A", it will be necessary to contact the TCSC to obtain the CVN information.

If a non-GM calibration is found to be in the ECM (CVN's on the Tech 2 do not match TIS printout) - In order to document the case — a CLEAR digital picture should be taken of the Tech 2® screen showing the VIN and the CVN's that do not match the TIS2WEB printout. The picture, VIN and reason the vehicle is currently in for service should be emailed to [email protected] and STEVEN.R. [email protected] for verification. Please copy your GM District Service Manager (DVM) on the e-mail. GM will verify if the CVN's are not GM issued and respond via e-mail within 72 hours.

its been posted but here it is:

That is something I found on another GM board a while ago. They have the same ability on the gas engine equipped vehicles as the diesels.

It will void it period, even if you remove the tune. The ECU keeps a record of the fact that it has been reprogrammed and dealers are required to retrieve this data as part of the warranty process. So tune = no warranty period.

This information is not true in all cases.

On applications where GM does check the CVNs, our tuning devices will not show up when used on the latest revisions.

So on a 2010 6.2 that has the original backup restored the CVN's will revert back to the original data that the handheld copied? So that should restore it completely with no changes from OEM configuration? Provided the handheld has the newest version of software?

Nytemare · April 13, 2010

So...bottom line is.....

If you want to test out the theory go ahead and try.

If you value your warranty...and are too scared...leave it stock.

Personally...I would try it....but I know my dealership wouldn't say anything. They loved how my truck drove with the tune that all the techs with silverados/serrias went out and got theirs tuned...actually the Finance guy did it for a couple of them with HP Tuners.

Yup.

The CVNs dont even change when there is a tune installed.....

Just keep your stock module for return trips to the dealer.

Mike....I have sent you a couple PM's with some questions.....have you received them? I dont see them in my sent messages for some reason

Mike@Diablosport · April 14, 2010

PM notifications are a little different here, I did not notice I had them, I have replied ;)
