As Simon explained, the reference pressure in the software is the pressure against which the ECU compares the current pressure to compensate for fluctuations in the supply. Your map is set to provide an injection pulse of x duration at y gas pressure where y is the setting your looking at. If the pressure reported by the sensor is y+/-z the ECU will make an adjustment to the injector duration to ensure the cylinder gets the correct amount of gas. Reference pressure should be set to match whatever the reducer is set to provide and if you go and change it to something other than the pressure the reducer is providing your ECU will be constantly correcting away from the value required by the map.
From what you said above, and Simon's post it sounds like your engine is now idling 25% rich.
At least, that's my understanding :)

I'd give it a try, although hot engine refers to coolant temp rather than ambient temp, I'm sure your engine will cool down more slowly than in the UK! It's really for situations where you're stopping and re-starting a hot engine. It'll save you some fuel but it's hard to say how much.
I'd have thought this wouldn't matter too much with an injected system, I can see why it would be different with a single point/mixer. Suck it and see, I guess?
Another backwards step was the removal of exemption from the London "Congestion Charge" which used to apply to LPG vehicles. I bet Londoners are SO happy that the clean running LPG builders vans were all replaced by diesels with NOx and particulates contributing to their record air pollution stats.

At my local ASDA, LPG costs 49.7p, Diesel 109.9 and Petrol 109.9.
There's absolutely no reason why manufacturers can't be told to produce factory fitted LPG cars to give your average non-tinkering motorist the ability to run a car on a lease and with a warranty. The reason it doesn't happen is the car manufacturers are scared that retrofitting LPG kits to existing cars will reduce sales of new ones. They're very happy with the Euro 4,5,6 ladder that penalises people who drive old cars.
IF we are to ever produce a greener economy (and I have serious doubts that it is remotely possible without people voting to return to a pre-industrial level of technology) then we need to rid ourselves of the "need" to buy new and dispose of perfectly good equipment. I can't see how we can produce a green consumer society when it's the act of consumption that drives so much pollution.
I'd be tempted by a Tesla, but even with their long range the charging time sucks if you're driving a long distance. In the meantime, we should just make LPG compulsory on every forecourt and convert all petrol cars. Ban diesels - they're just terrible.
Fantastic news :)
Welcome to semi-affordable motoring!
I'm sorely tempted to set up a VM at work and stick Centos and a web server on it, but that would be a bit naughty. Although, we do get our bandwidth free of charge... hmm.
Whatever solution is promoted, I can guarantee it won't be something that allows us to re-use existing vehicles but requires new vehicles. This is the main problem facing LPG - it doesn't get the blessing of the SMMT because it doesn't involve accelerating the product lifecycle and the Government don't like it because it leads to reduced tax income.
These are two reasons I LOVE it.

Just cause you read the Hadron Collided manual, doesn't mean your able to fix it.
Chuckles :)
Good on you Mr Devon :)
That's a really nice looking wagon, congrats!
I wish I could find some green lanes to play on, but it seems they've come under a lot of pressure in Yorkshire recently. Also, people seem to be quite secretive about them.
Still, there's nothing wrong with a P38 running on the road. Most of them see nothing else!
Bought! Thank you :)
It should, yes.
The last time I enquired of the stealers they wanted £170 and told us that all replacement keys are now Key1. The key I have is Key2 so that's OK by me but it seems pretty odd. I tried 2 local dealers and they both told me the same thing.
The first one was just for interest. I quite like the aftermarket nav setup, at least as far as you can see it in the photos.
There's a 30th anniversary on too. Only 10 grand. <Sigh>
Neither of them are Diseasels! :)
While I'm trawling ebay - here's another cheap fix for someone :)

Not sure why the MOT guy tested it as a diesel... but hey.
Not that you need another one but I thought you might be interested in the aftermarket Nav which looks quite well done. Nice Oxford leather too :) Shame about the chav-tastic exhausts. (IMHO)
I wish, but there were witnesses and she was already strapped into a stretcher.
I think the original owner of that car REALLY wanted an M5 touring but they weren't available so he made the nearest thing from the option list.
MORE for LPG than petrol? You live in a crazy place :(
But don't be a stranger, or we'll convoy over and invade you :)
Ahhh, you're talking about wing mirrors. They move to the memory location just fine. I misunderstood and thought you meant the driver's mirror which doesn't (but did on our old 5 series of similar vintage)
