    Read the AutoVE tutorial mate, it covers going into SD and tuning the VE table etc.

    Thanks for the reply, I have read the AutoVE tutorial, maybe you could tell me what custom operating system I use for this 2006 VZ L76 6 litre engine operating system 12607218 to run speed density?

    Don't need a custom OS mate as the car runs an E38 Controller.

    Have a read of swingtans tutorial. It covers what you need.

    Thanks macca, this confirms what I thought was the case, good tutorial by swingtans saves me finding the appropriate wire.

    The only thing I need to confirm now is, is the hi and low octane ignition tables still active? from what I understand they are still active when the MAF is unplugged unlike the LS1.

    The only thing you will loose when going SD on an E38 is the traction control / stability control will not work. But, to fix that you will see a section called Operating System patches, you need to apply both TCS patches and then all that will be functional when in SD.

    Default License

    Another question do I require one license to tune this vehicle or two ie one for the engine and one for the transmission?

    You have to have a V2 to read/tune this car and it uses 1 VIN license (aka you can tune 1 ECM and 1 TCM).
