    Default WARNING To Owners with Tuning Box's

    As you know, my car is in the process of having the DMF changed, and I had an interesting chat today.

    Vauxhall have become aware that Vectra/Signum DMF problems can be highlighted and made worse by the use of the tuning box. Dealers can check what max pressure the fuel pump has been running at and can compare it to the max pressure it should be running at.

    If there are descrepancies, a warranty claim can and will be turned down. Vauxhall are checking for this now on cars they suspect have been messed about with.

    The reason so I am told is that the tuning box does not limit the torque in first and second gear and puts major stress on the DMF.

    You have been warned!

    Ok, well here is a thought. Vx must read the fuel pressure data from a memory bank somewhere. I wonder if this data will be wiped if you disconnect the battery overnight????? If so, therein lies the answer to you boxed people. Just a thought.

    But driving in a sensible manner while in first and second shouldn't cause an issue? Who would be stupid enough to boot their car in first and second gear all the time anyway, and putting the max torque through the drivetrain?
    Doing that would kill the clutch eventually on most cars.

    just recieved a very intersting email from Peugeot regarding power kits (diesel tuning boxes) being fitted to their vehicles -
    "

    We have been alerted in Germany by several cases of melted pistons on the 2.2 litre diesel engine.
    The technical inspections carried out on two of these incidents have concluded that the most likely cause was the fitting of a power
    kit. One of the units analysed misled the ECU input parameters resulting in an injection rail pressure several hundred bars higher
    than it should have been."

    they are now advising all dealers to check all vehicles with running faults
    and report any case of suspected or fitted kits to contact them immediatley as warranties would be invalidated - just thought i would make you aware as most manufacturers follow suit very quickly regarding such matters

    for your information

    I am guessing that Remaps don't have the same effect as they are tuned specifically to the car and most remaps put a limit on the torque (300lbft)(especially for the 150's) as the DMF's can't handle that much torque.

    Am I right in saying this?

    I would say that some stored data isn't volatile and therefore removing the battery will not delete it.

    As I said previously, why should VX pick up any failure costs for those people who fit deevices that take the engine out of it's normal, validated operating areas? Surely it should be at own risk?

    Have to agree, once you start messing with a car it isnt how it left VX so really they should have no responsibility as its not normal wear and tear
