Got the gas kit yesterday and it is considerably more advanced than the old one - rather than having to create a separate map for the LPG fuelling it intercepts the signal from the petrol injectors (thereby using the vehicles original map) and adapts that for the injector timing needed for LPG, altering it based on ambient/gas pressures and gas temperature. It also means the revs will be raised when things like the A/C compressor kicks in (the old system was slightly prone to stalling). Injectors can be batch or sequentially fired - so when switching fuels it will (should?) do it seamlessly. Rather than simply taking signals from one lambda sensor and adjusting the fuelling based one one bank the new ECU takes signals from both lambdas, and also can communicate with the original ECU via the OBD socket!
I was chatting to the kit supplier after I'd decided to buy it and he was saying they don't usually supply DIY but the number of installers (his customers!) that he'd trust with his vehicles he could count on one hand…
I told him of my experiences and he said "It wasn't Hardys was it?" These were the second lot I went to and it turned out he'd had Simon Hardy on the phone bragging how he'd had a customer in (me) and how he'd probably end up charging £300 for diagnostic time and no guarantee of fixing the problem - and then he'd end up fitting a kit if unsuccessful. Glad we didn't take it there in the end then.
