Has anybody on here had there 3.2 ecu remapped then run it on lpg ?
I know that remapping can give you a little extra grunt / better fuel economy but would you get similar benefits afterwards when running on gas (after the lpg was remapped) ?
Sorry for the slight thread drift 
Yep, have a Manual 3.2 Plod Saloon thats had its ECU remapped plus a performance Exhuast, although I've no idea how the LPG ECU is mapped?, just hooked on the end of it as far as I know.
Whilst the Remap on the 3.2 makes the car feel like it has more grunt, in particular when accelerating, cant honestly say it gives much improvement on overall MPG, having said all that Ive always had a Bee in my Bonnet about the poor economy of the 3.2 compared to the earlier 3.0's.
I've played about with a few chips, or mapping if you like, on the 3.0's, to include SuperChips, Courtenay Tunning, some Plod ones plus others, and found overall whilst they seem offer small BHP gains,they do improve drive ability and improve MPG on the car.
Hence my post further up regarding a Chipped 3.0 LPG vs 2.5TD. ;
