Hi, You guys in the UK & Europe are more advanced than us re LPG; as we have 'less' urgency to use it as our petrol prices are a bit lower.
What brand & model of LPG system did you have fitted to your LS400 ? I understand that a sequential injected LPG system does not operate in sequential mode on a car that does not have true sequential fuel injection ECU; meaning that many earlier toyota EFI systems are grouped injection (so 4 injector fire together, then the other 4 etc) vs true sequntial where the 8 injectors fire at separate times. An LPG installer told me that grouped injection engines on LPG, will have a much higher risk of backfire & not run as smoothly because the LPGas is 'sitting around for longer (more micro-seconds) in the inlet manifold for longer before being used. I would like your feedback re: how your system has gone for you & what type, brand, model of LPG system it is. For those looking to LPG a LS430; seq-gas-in is best as the 430 has a true seq (8 injectors fire all at independent times, not in groups of 4's) efi system.Thanks in advance Andrew (email- invest1234@gmail.com) Australia.
