I wish i could find that document number so i could post it but ive searched for over an hour and cant come up with it . O'well you got to pay to play i guess.

If someone comes off like a blow hard know it all that isn't at fault for anything, odd's are they reek of evasiveness and guilt.

There are some douchebag dealers out there to be fair, but painting them all with the same brush is a stretch IMO. Everyone is entitled to their opinions of course, but it blows my mind the sense of entitlement from some people. If you made something and sold it to someone else, and they brought it back broken after they changed the original way it came...would you be cool with fixing it for free when what they did to it could possibly be the cause of the issues? I'd think no. But thats just me. If it's unrelated, then hell ya...they should totally eat the costs.

--------------------------------------------------------------------------------

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):


Go to TIS2WEB
Select "Calibration Information (SPS Info)"
Enter VIN
Select "Get Cal ID"
Select "ECM Engine Control Module"
Select "Next"
Select "Complete History"
Print
Take the printout to the vehicle along with the Tech 2Ž
Plug in the Tech 2Ž
Go to diagnostics and build the vehicle
Select "Powertrain"
Select "Engine"
*Select "Engine Control Module" or "PCM"
*Select "Module ID Information" or "I/M Information System" if module ID information selection is not available.
*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.
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 2Ž 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 and 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.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the information.

GM is now checking your tune VS the stock factory tuning by the process outlined below and if a non-stock tune is found you just had your warrenty voided. CONGRATS! They're also gettin sneaky and counting how many times a car has been flashed as its stored in its memory FOREVER and if they see any signs of it being done anymore then the dealer themselves did it, again voided warrenty! Basicly if you're tuned and you blow your engine or trans or any drive line parts YOU'RE SCREWED!!

Here's the actual TSRB. So be warned all ye tuners GM is coming for you, to put you out of business!! You WILL be caught and you WILL have your warrenty voided!! PERIOD!!
Hey they gotta save every penny they can so Mr. Obama doesn't close them up all together!

BTW if anyone here could get a copy of corporate bulletin 08-06-04-033D as listed in this TSRB heading as it applies to "ALL OTHER GAS ENGINES I'd be willing to bet it says the exact same thing for ALL GM cars and trucks. Meaning YOU GUYS TOO!!!

#09-06-04-026: Identifying Non-GM (Aftermarket) Engine and Transmission Calibrations for V8 Gas Engines - (May 18, 2009)


Subject: Identifying Non-GM (Aftermarket) Engine and Transmission Calibrations for V8 Gas Engines


Models: 2006-2009 GM Passenger Cars and Light Duty Trucks (Excluding Saab 9-7X)

2006-2009 HUMMER H2, H3

Equipped with V8 Gas Powered Engines Only



Attention: This bulletin applies to V8 gas powered engines ONLY. For all other gas powered engine applications, refer to Corporate Bulletin Number 08-06-04-033D. For diesel powered engines, refer to Corporate Bulletin Number 08-06-04-006C.



--------------------------------------------------------------------------------

General Motors is identifying an increasing number of engine, transmission and catalytic converter part failures that are the result of non-GM (aftermarket) engine and transmission control calibrations being used.

When alteration to the GM-released engine or transmission control calibrations occurs, it subjects powertrain and driveline components (engine , transmission, transfer case, driveshaft and rear axle) to stresses that were not tested by General Motors. It is because of these unknown stresses, and the potential to alter reliability, durability and emissions performance, that GM has adopted a policy to cancel any remaining warranty coverage to the powertrain and driveline components whenever the presence of a non-GM (aftermarket) calibration is confirmed - even if the non-GM control module calibration is subsequently removed.

Warranty coverage is based on the equipment and calibrations that were released on the vehicle at time of sale, or subsequently updated by GM. That’s because GM testing and validation matches the calibration to a host of criteria that is essential to assure reliability, durability and emissions performance over the life of the warranty coverage and beyond. Stresses resulting from calibrations different than those tested and released by GM can damage or weaken components, leading to poor performance and or shortened life.

Additionally, non-GM (aftermarket) issued engine control modifications often do not meet the same emissions performance standards as GM issued calibrations. Depending on state statutes, individuals who install engine control module calibrations that put the vehicle outside the parameters of emissions certification standards may be subject to fines and/or penalties.

This bulletin outlines a procedure to identify the presence of non-GM (aftermarket) calibrations. GM recommends performing this check whenever a hard part failure is seen on internal engine or transmission components, or before an engine assembly or transmission assembly is being replaced under warranty. It is also recommended that the engine calibration verification procedure be performed whenever diagnostics indicate that catalytic converter replacement is indicated.

In May 2009, the PQC will begin piloting a process to confirm the ECM/PCM calibration is GM issued. Beginning on May 18, 2009, the PQC will require a picture of the engine calibration verification screen, as outlined in this bulletin, before authorizing any V8 gas powered engine replacement.

If a non-GM calibration is found and verification has taken place through GM, the remaining powertrain and driveline warranty will be cancelled and notated in GMVIS and the dealership will be notified.

•Plug in the Tech 2Ž.
•Go to diagnostics and build the vehicle.
•Select "Powertrain".
•Select "Engine".
•*Select "Engine Control Module" or "PCM".
•*Select "Module ID Information" or "I/M Information System" if module ID information selection is not available.
•*If "I/M information System" was selected, it may be necessary to select "Vehicle Information" in order to display the calibration information.




•Take a CLEAR digital picture of the Tech 2Ž screen showing the engine calibration verification information as shown above.
•E-mail the snapshot picture to ****. In the subject line of the email include the phrase "V8 Cal" as well as the complete VIN and Dealer BAC. In the body of the e-mail, inlcude the VIN, mileage, R.O. number and BAC.
•Allow two hours for the PQC to verify the calibrations and set up the case details.
•You may call the PQC two hours after submitting the e-mail for authorization to replace the assembly. This will provide them time to receive, review and set up a case on the request. Please be prepared to provide all the usual documentation that is normally required when requesting an assembly authorization from the PQC.
If the CVN information is displayed as "N/A", it will be necessary to contact the TCSC (1-800-222-2222 English or 1-800-222-2222 French) to obtain the CVN information.

Im GM and I own a pet store. You come in and buy a turtle from me. I give you my word that the turtle will live and be as normal as a turtle can be for a month. After 3 weeks goes by you come back in and your turtle is walking sideways and not feeling well. I look at the turtle and you cut one of his legs off for whatever reason. I say sorry I cant help you and you get pissed. So i'm the bad guy?
