    note:v8 gas

    Looks like the new GDS (Global Diagnostic System) is going to be pretty tough to fool when it comes to tunes . The screen shot of the software shows a history graph of the last 10 calibrations with the part numbers and amount of times it has been flashed . No more tech 2 CVN's .....now they will be using laptops with MDI interfaces.

    #09-06-04-026B: Identifying Non-GM (Aftermarket) Engine and Transmission Calibrations for V8 Gas Engines Using Tech 2 or Global Diagnostic System (GDS) - (Apr 7, 2010)

    Subject: Identifying Non-GM (Aftermarket) Engine and Transmission Calibrations for V8 Gas Engines Using Tech 2® or Global Diagnostic System (GDS)

    Models: 2006-2010 GM Passenger Cars and Light Duty Trucks (Excluding Saab 9-7X)
    2006-2009 HUMMER H2
    2006-2010 HUMMER H3
    Equipped with V8 Gas Powered Engines Only

    Attention: This bulletin applies to V8 gas powered engines ONLY. For Duramax™ diesel powered engines, refer to Corporate Bulletin Number 08-06-04-006G.

    This bulletin is being revised to add the 2010 model year and information about retrieving calibrations on a Global A vehicle. Please discard Corporate Bulletin Number 09-06-04-026A (Section 06 - Engine/Propulsion System).

    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 that prevents any UNAUTHORIZED dealer warranty claim submissions to 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 from 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.

    The PQC has a process to confirm the ECM/PCM calibration is GM issued. 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 blocked and notated in GMVIS and the dealership will be notified. This block prevents any UNAUTHORIZED warranty claim submission.

    1. Connect the Tech 2® to the vehicle.
    2. Go to: Diagnostics and build the vehicle.
    3. Select: Powertrain.
    4. Select: Engine.
    5. *Select: Engine Control Module or PCM.
    6. *Select: Module ID Information or I/M Information System if the Module ID Information selection is not available.
    7. *If "I/M information System" was selected, it may be necessary to select "Vehicle Information" in order to display the calibration information.
    ⇒ If the CVN information is displayed as "N/A", it will be necessary to contact the TCSC (1-800- English or 1-800- French) to obtain the CVN information.

    Click here for detailed picture of above image.
    8. Take a CLEAR digital picture of the Tech 2® Vehicle Information screen showing the engine Calibration IDs and Verification Numbers as shown above. Retain the printout information and the Tech 2® screen photograph with the repair order.
    9. E-mail a copy of the picture to xxxxxxxxxx. In the subject line of the e-mail include the phrase "V8 Cal" as well as the complete VIN and Dealer BAC. In the body of the e-mail, include the VIN, mileage, R.O. number and BAC. Include a brief description of the customer concern and cause of the concern.

    Note: The dealer will receive an e-mail reply after the calibrations have been validated. The e-mail reply will advise the dealer if the calibrations are OEM.
    10. Allow two hours for the PQC to verify the calibrations and set up the case details.
    ⇒ If the PQC determines that the calibrations ARE aftermarket calibrations, DO NOT contact GM Technical Assistance to discuss warranty concerns on the aftermarket calibrations. ALL questions and concerns about warranty should be directed to the dealers Fixed Operations Manager (FOM), (Warranty Manager (WM) in Canada).
    11. 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.

    Tech 2® Displaying All Zeroes for the Verification Numbers on the Calibration ID and Verification Number Screen

    Object Number: 2363198 Size: SH
    Click here for detailed picture of above image.

    If the Tech 2® that you are using displays all zeroes for the Verification Numbers as shown, then perform the following steps:

    1. Update the Tech 2® with the latest software from TIS2WEB.
    2. Turn OFF the ignition for 90 seconds.
    3. Connect the Tech 2® to the vehicle.
    4. Turn ON the ignition, and build the vehicle. Observe the Tech 2® Calibration ID and Verification Number screen for proper operation.
    ⇒ If the Tech 2® screen still does not display properly, then turn OFF the ignition for 90 seconds again. Turn ON the ignition and observe the same screen for proper operation.

    Retrieving Calibrations From a Global A Vehicle

    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.

    yeah we usually do this
    http://www.sandyblogs.com/techlink/2009/01/the-meaning-of-goodwill.html
    if you're not under warranty and you're factory.
    a car like mine would never get goodwill
    also we don't really check for shit like that unless a sensor keeps blowing or something pcm related. just make an effort to look stock when you're trying to go through warranty
