    Revo remaped ecu in to my a3 1.8 agu

    Just bought an ecu that has the stage one revo remap, I've been told that when the ecu has been removed from the car
    That it locks itself?? Has to be decoded some how to unlock it so then can be fitted back in again+get the engine up and running?
    The person I purchased the ecu off wasn't to sure if it was plug any play so thought he would mention this^^^

    Could anyone shed some light On this? I just don't really want to remove my ecu so I can replace it with the remapped one then the
    Car not starting with it been locked!!

    Both of the cars have the same agu engine code!

    The agu engine has the earlier immo2 immobiliser, if you swap your ecu the replacement ecu will need coding to your clocks and key, being an early car it's actually straight forward for someone with vagcom. Where are you dude? I'd happily code that for you if you're local ish.

    I live on the south coast! Might be a bit if a trek! Lol. It's a simple procedure if you can find someone with a full version of vagcom. I don't think the eBay 'lite' versions let you change coding.

    Quote:
    Immobilizer II:

    The immobilizer will prevent the car from running without a matching key microchip. There is a symbol in the instrument cluster showing a key inside a car. If a new (or different ECU) is installed in the vehicle, the immobilizer will prevent the car from running and will cause the symbol to flash. Here is the procedure to introduce a new ECU to the instrument cluster. This must be performed each time ECU's are exchanged. This does not apply to installing a "chip" in the same ECU that is already aligned with the car.

    Immo-3 knows your car's VIN. Access 17-Instruments (or separate 25-Immobilizer on vehicles that are set up that way) and look at the first "Extra" field.

    If you see something like: "Immo-ID VWZ7Z0W0648696" You've got Immo-2 (or maybe even Immo-1 in earlier non-US models).

    If you see something like "WVZKB58001H231169 VWZ7Z0W0648696" You've got
    Immo-3. The first 17-digit string is the VIN. The second 14-digit string in the Immo-ID.

    Install the new ECU in the car
    [Select]
    [17 - Instruments]
    [Adaptation - 10]
    Leave channel at "00"
    [Read]
    [Save]


    [Done, Go Back]
    [Close Controller, Go Back - 06]
    [Exit]


    Turn ignition OFF for 15 seconds. Start vehicle.

    Note: For cars with a separate Immobilizer (Includes 2000+ EuroVan, Cabrio, and many older non-US models), use [25 Immobilizer] instead of [17 - Instruments]. The rest of the procedure is the same.

    I'd say 18 psi is about all a KO3 can manage. I know thats what mine is running with CC stage 1 after it being on the rollers at Bills last year

    So was it instant after they remapped it? Or did the boost have to be messed around with? I've fitted this ecu had it decoded and yea it
    Seems abit nippier but still boosting just below 10psi :-/ and I'm sure standard boost is around 8?

    If you can't get a full version of vagcom buy a vagtacho cable off ebay and that will do the coding for you, very simple and it's only £22

    Yea I'd say so. Checked all the pipe work. All seems ok. Taken it down the road and when under full throttle getting to higher speeds the boost slowly drops on the gauge between 0 and 10 psi :-s

    As bill says, with revo maps they can be switched between stock and mapped on your ecu. Your local revo dealer can check this for you. Again I'd offer to help but you're the wrong end of the country dude.

    You're relatively lucky as with the later ECU's Revo maps are linked to the VIN in the car, so you can't swap ECU's around... when you do and the ECU is coded to the car you lose any Revo code. On the M5 ECU they can be swapped, however I'd imagine it's coded to 'Stock' and the software needs to be switched on.
