VR Commodore XDF?

[Lunitech]

Hi
I need to remove the VATS security check from a VR Holden commodre ECU as the engine has been transplanted into a different car.

Can anyone tell me the location of the byte to change or does anyone have a XDF file with this option?

The ECU is a 16211768 and the eprom code is BMZB

Also is the eprom a 27C256 as the part number on the chip is not one that I recognise

Thanks
