No I don't have an xdf for the LPG.
Tables are relatively easy to find, but scalars are rather tricky.
Basically uses the MAF and O2 sensors, and then has a PWM output for LPG flow control valve(FCV) from the PCM to control the LPG mixtures. NOTE: setup for a rich bias lpg system and will not work with a lean bias lpg system.
If I was ever doing LPG on a VY again would probably use vapour injection and a VT PCM with moates g6 adapter runnning 2 separate tunes, one for gas and one for petrol.

Re: vy vr running gas
digging up an old thread, but does anyone have a diagram or manual for how the vacuum lines are configured on the factory lpg systems. I have a vy with factory gas and suspect it's been played with in the past and want to make sure it's setup correctly.

Re: vy vr running gas
Has anyone used the VT-VY PCM retuned to control LPG vapor injectors?
rather than using a LPG ECU, I would like to hear if anyone is running vapor injection on a delco PCM
