Title: My LPG Savings - after conversion
Post by: JamesV6CDX on 02 December 2007, 12:02:36
£70 of petrol, at £1.02/litre - 300 miles to a tank tops, driving hard

£30 of LPG, at 45.0p/litre - 280 miles to a tank, again driving with a very heavy right foot.

My fuel costs have more than halved...  :)

Its' really not far off running right, to be honest...  

I rekon the bit of hesitation is an air leak somewhere..

Could be that the fuelling is not 100% yet. Our quick tweak got it pretty good, but I reckon another tweak now it's bedded in (probably best once the misfire is cured) would be worthwhile.

Under what conditions does it hesitate? On gas / petrol / both? Cold / Hot / both? blipping from idle? Putting your foot down whilst underway? Under constant cruising?

It could simply be that the acceleration enrichment is set up for petrol, and of course the same enrichment is applied for gas, so maybe it's par for the course :-/ There's a bit more pipework for the gas to get through when you blip it so maybe a bit more delay in the fuelling picking up.

It may be a little 'off' at the moment, as lpg needs a 1000 miles or so to settle down as it clears the crap out.

Just to add to the theory regarding lpg, and the slight missfire when you blip the throttle. I have been driving an lpg transit connect for the last 4 years as a company hack and it has had the 'miss' ever since new, and has been to ford for them to check it, all the system checks out ok and you come to live with it. I think it may be that the lpg is less dense than petrol and ignited in a different way to petrol. :-?
