i have only gone and finished the install, no really, only a year after buying the car and telling myself to put lpg on it asap. Ffs...(actually only took about 6days work once i had all the right bits and Kevin very kindly wired the ecu, not to mention a back up manifold from Lazydocker :-) )
Anyway, plugged the lap top in and ran the set up, got 2 errors from the software.
1, no signal from injector no 4. Will look into that later as the plug is fully home.
2,injector nozel not big enough. More concerned with this one as the nozels are drilled out to 3mill as advised by Kevin and Moto gas. So, is this adjustment on the vapourisor, 10 mill allen key in the centre with plus and minus pressure on it?
Must admit it was a bit of a rush this morning so didnt really have time to play with it before i had to pack up for work. Any words from the wise before play tomorrow?
Also there is a brass screw/knob on the level valve on the tank, i presume this is to isolate the gas flow to the vapourisos and needs to be backed fully off? It has "36bar" written on it, or something like.
Cheers
Chris :-)

About time too!!! :D :D :D :D :D
Anyways... Did you adjust the pressure on the vaporiser before fitting it? The large allen bolt you talked about, 10mm IIRCC, needs to be turned in approx 3 turns (I think) Basically you want around 2.5-3 bar LPG pressure showing on the software.
1, no signal from injector no 4. Will look into that later as the plug is fully home.
Are you getting any values at all showing? I hope you haven't got a dodgy connection under the plenum ::) ::)

Hmmm... That's odd. I would have expected you to get nozzles too big :-/ :-/ :-/ That's what I was getting, took 3 attempts to get it to auto calibrate. Could be that the pressure is too low if you didn't do as above

have i got to read the instructions then. Missed the 2.5-3 bar bit. Hopefully thats causing to small nozel thing. And yes will probably have to take plenum off again for the injector issue.

break it... My dyslexic fingers! 1.23-1.3 bar!
Sorry Chris! Errm... Nope, not in the instructions, just our experiences :y :y

Looks like i need to up mine more then, as im only reading 0.98 although Kevin reckoned 1 is about right :-/

If it's running OK then don't bother changing it!!!

Its fine apart from rapid pull away where it will bog down/hicup :-/ :(

calibration finished successfully. Wa hay.:-)

What happened with the Injector 4 signal?
Now you just need to map it... May take a couple of goes though ::) ::)

Mine does have a hiccup as it changes from 1st to second at 5200RPM+ so I have set it to switch to petrol at this point... After all, it's rare it gets to that point ::) ::)

Mine only hicups on pull away only :(

Dont know. Took plenum off checked all the plugs not just no.4. Found nothing. Well, found a breather pipe clip, eventually, right under the rather coolent bridge. Why do always get right down there? Re fitted. Plugged lap top in set the pressure to 1.23 bar, with a bit of fiddling as it warned up, and ran the calibration. Bingo. Job done.
First maiden lpg voyage? Curry house, its only right. :-)
Did give it a boot, no hick ups at all. Cant fault it so far. Will give it a proper work out tomorrow when the Mrs isnt screaming in my ear, but so far, do i need to go any further with it?
Oh one thing, went to fill up and got a squeak at 35 litres ish, released the button immediately as i was unsure what it was? Do they squeak when full? Level sensor on dash had 4 lights but havent set that up yet so may well not be actually full.
Cheers. :-)
-
They squeak when it gets more difficult to pump - stop filling when it cuts the motor, you cannot overfill

Aeye. Cheers Martin. :-)

Have you got the mapping done... Ideally you want bother the petrol (blue) and LPG (green) lines to be as close to each other as possible.
-
Excellent news. :y
As said, about 1.25 to 1.3 bar and 3mm nozzles seems about right for a 3.2.
I would avoid giving it serious beans on LPG until you've manually checked the mapping. They need a bit of tweaking after the auto calibration IME. Make sure that the lambda sensor outputs both go high and stay solidly high over the whole rev range on a wide open throttle. That way you know it's not going lean.
If you really want to perfect the map, connect a code reader to the OBDII port, reset the block learning and tune the LPG system until the fuel trims stay close to zero over the whole range of speed and load.

Nope. Not busy at all. I am in Waterford, Southern Ireland, though. :-/

Bumpy as break in a Westfield, but deserted compared to our area. Am surprised nothing's fallen off the car yet.
I'm back next week so if you want to borrow a passenger-seat-mounted electro-biological LPG mapping device we can sort something out then.

Good stuff, see you then. Will lay off the loud pedal til then. :)

Hi Chris
just read bout lpg install
I'm driving 2.2CD Auto X reg with Leonardo LPG sys.
Any chance you'd let me know how much have you pid for your sys and what's the make? Mine'spretty old and thinking of getting the new one :)
-
I had to lean mine off to prevent dropping to petrol at WOT.
That is what AGWW told me to do

Surely they didn't advise that! Leaning is the last thing you want... It's better to richen it if anything! If it leans out at WOT you run the risk of serious damage as the combustion is too hot :o :o :o

They said it would be fine ::)
That said still runs fine but we will see on Saturday when I remove a head

Can't remember what he charges for a 4 pot system but to give you an idea... I paid £650ish for my full kit, including tank, for a 6 pot. Take off at least £200 for the tank and it's £450ish for the front end kit (plus a few extras) so I would think a 4 pot kit could come in under £400 all in, especially if you spoke to Teilo and explained that it's an upgrade from a Leonardo controlled single point so you wouldn't need all of the extra's he throws in! :y :y :y

Agreed. A lean mixture is very bad news. If it can't keep up with demand, best to let it switch over the petrol rather than burn a valve or melt a piston.
Check that both Lambda sensors read a solid rich when "on it" otherwise you are on dodgy ground, especially if towing, as the engine will get WOT for longer periods.

Which is why, even though mine seems to stay rich at WOT, I have opted to drop onto petrol over 5200RPM just in case :y :y :y
And to avoid the annoying drop off I seem to get :-/ :-/ :-/

No way of monitoring Lambdas for me I am afraid.
They said to me on WOT it runs rich anyway (not sure about that)
If it drops to petrol it then over pressures the system.
Might need a biological monitoring unit some time ;D

However 3 years running on gas - about 1800 miles towing, it doesn't seem to get hot either.
Tomorrow will tell when I whip off a head
