What is the point of having an 'official LPG specialist' on a forum who never posts on that forum?
[
http://www.lexusownersclub.co.uk/forum/topic/110146-near-death-experience-with-lpg/And while we're at it, a lot of LPG advice on that forum from others is duff too - particularly advice that would have people with LPG systems other than Stag visiting the 'official' LPG installer of that forum (again because the official LPG installer of that site only fits one LPG system out of the hundreds of types that are in circulation, so will be unfamiliar with and not have parts for systems other than Stag). Just reading this could prevent someone have a wasted 300 mile round trip.
Pity I'm banned from posting on that forum by the moderator Bluesman, or I would have advised the OP in the above link correctly immediately!
Where are the replies from Bluesman's preferred installer (that firm in South Wales)? Ahh yes, the boss of the 'official' LPG firm of LexusOC is in jail for killing a cyclist while taking pictures with his mobile phone when driving a minibus (as Bluesman knows very well) - but don't they allow inmates to use computers these days?
In this thread
http://www.lexusownersclub.co.uk/forum/topic/107601-missfiring-like-its-gone-out-of-fashion/?page=3 Bluesman and other LexusOC forum users seem unaware that incorrect open loop fuelling while running on LPG (too rich, as opposed to the too lean which someone on that forum stated) can lead to failed catalytic converters.. And the official LPG company of LexusOC forum don't tune LPG system mixture under open loop fuelling conditions properly (in fact they don't tune LPG systems properly at all, instead leave LPG systems to 'autotune' which no LPG system can do properly, but the worst aspect of autotune is that it doesn't address open loop fuelling at all). It is likely that Bluesman's own vehicle problems, which cost him a lot of money and many weeks without having the use of his car, were caused by his LPG system which he had fitted at the firm he advises everyone to use. And then, having eventually realised that blocked cats were the immediate problem, nobody on that forum realised that the best fix would be to de-core the cats (and cheaper since no new cats would be needed). A vehicle running on LPG will pass the MOT without cats, and may achieve a bit better economy and have a bit more power to boot. Having read about the symptoms, and knowing about the LPG installers 'autocal' method of calibrating Bluesman's LPG system, I would have advised blocked cats as potential reason for the immediate (misfiring) symptoms at a very early stage in that thread so would/could have saved Bluesman a lot of wasted time (without his car) and money! Now that the cats have been replaced it is still very likely that the mixture on LPG was the cause of the problem in the first place, so Bluesman is still very likely driving around with the real cause of his recent several weeks without his vehicle and hefty repair bills still present, so driving around with a real risk of damaging his new cats or engine. If that is the case (very likely), any money Bluesman saved on having his LPG system fitted by the firm he recommends has ended up costing him a lot more money and time without his vehicle than a proper job of conversion and calibration would have cost him. A cheap LPG conversion 'done in a day' doesn't seem a great idea if it ends up working out to cost a lot more money and several weeks without the car in the long run - we'd be talking 3 days and a couple of hundred quid more for a conversion done by an installer with a good reputation who would do a great job of installation and calibration, much better than spending many weeks without the car and spending hundreds of pounds repairing issues caused by a less than ideal LPG setup. Ignorance bliss Bluesman!
