Re: New member but long time reader

Welcome from me too, it makes a change to find someone who has the right mindset to learn how something works, how it comes to bits, take it to bits and then fix it. You are a dying breed my friend. I'm like you. I could buy something small and economical as a run around and keep my 4.0 litre V8 pow...

Re: Problems with Bigas system on Audi S6 V8

Sounds like you've sussed it. You are absolutely correct, as the LPG system piggybacks off the petrol system, so if the LPG system is providing too much gas, the petrol fuel trims go lean to correct it. As soon as these trims reach a predetermined level, it brings on the CEL. Once you get the cable ...

Re: High HC levels at idle.

Depending on the make of gas analyser, it may actually be worse than you are measuring. From the MoT testers manual: Testing LPG engines The hydrocarbon (HC) emissions on vehicles running on LPG are propane and not hexane. The HC reading obtained must therefore be divided by the 'propane/hexane equi...

Re: High HC levels at idle.

Might do depending on what the standard gap is. Some plugs come gapped at 1.1mm, the equivalent to about 40 thou and closing them down to nearer 25 thou, or 0.8mm will help. That only applies to standard single electrode plugs though, don't try it with the multi-electrode type.

Re: High HC levels at idle.

When did you last change your spark plugs? The HC figure is unburnt hydrocarbons so a high reading means unburnt fuel coming out the tailpipe. A high HC figure, assuming the CO figure is normal, suggests incomplete combustion but only when running on LPG. As LPG needs a better spark than petrol, tha...

Re: Need Help - Hesitation on First Move

Cant' help you too much so you'll need to wait for Simon but the difference between pinj and ginj should be between 1.2x and 1.5x, ideally closer to the lower figure. So for your displayed pinj figure of 3.59 (second photo), ginj should be between 4.31 and 5.38 and not 7.61mS. That would explain you...

Re: lpg feed pipe size on 500 bhp engine.

I wouldn't trust anything with MSD on it as far as I could throw it. I've imported numerous older British cars (mainly Jags and Austin Healeys) from the US that would originally have had a Lucas distributor. The Yanks have taken them off and fitted MSD conversions as, having a sticker saying Made in...

Re: Prins lpg help please

Quite normal on some cars. The trip computer doesn't measure how much fuel you are using, it calculates how much it thinks you are using. It calculates it from knowing the fuel pressure and the length of time the petrol injectors are open for so can work out how much you have used. When running on L...

Where's that then? According to Filllpg.co.uk, you've got Smithy View Garage at 54.9p and Morrisons showing as LPG temporarily unavailable.

Re: Pop and bang on LPG

The gas, being a dry fuel, will stand less chance of washing the bores than petrol would so if the petrol ECU is set to give this affect, then a multipoint, as it follows the fuelling strategy of the petrol ECU, should do the same. I've recently had use of two cars that did this by design. The first...

Re: Recommend me a approved installer in the midlands

It may be multipoint but is it port injection, where the injectors squirt fuel into the inlet manifold before the valves or direct injection where they squirt directly into the combustion chamber. If port injection, it's a simple conversion, if direct injection it isn't. I would have thought 2012 wo...

Re: Zetecs on gas and multiple tanks

The Zetec has a reputation for having valves and seats made of something marginally harder than butter so will burn valves unless the system is set up properly and it has a valve saver fitted. Although people will tell you that an injected engine needs to have a multipoint, unless it has a plastic i...
