People who know LPG better than me (ie everyone!) do say that it takes about 1000 miles for the system to bed in on older engines (something to do with the cleaning effect of gas), and will need resetting again at 1000m

[Kevin Wood]

So, did the LPG conversion behave for you today, Jay w?

oh yes......240 miles on LPG and the guage on the tank is just above the red (70l tank)

at some points we were cruising down the a303 at slightly more than legal   and it was very smooth

i noticed on some of the long hills around stonehenge it was missing a but if it had a lot of throttle for a long time, switch back to petrol, get to the top, flick back to LPG and all was well.

MID is showing average of 36.7 mpg and then there is the novelty of doing all that mileage and not watching the fuel guage drop quickier than the titanic

just got to get the LPG guage sorted and then it will be sorted

about a fortnight then for me

IT WORKS!!

Excellent news

Keep an eye on it. I wonder if that injector was just stuck or maybe the wiring is a little loose in one of the connectors. Anyway, congratulations. You must be very happy after the rocky ride it's given you over the past couple of weeks!

You need a good spark for lpg.....and ive been recomended to open the gap up a bit by a few thou.....for single electrode plugs.......just about imposible to do on twin or quad plugs tho, so as i fit twin electrode plugs I leave them preset at 1mm.

Opening the plug gap does give you a more powerful spark up to a point, if you have enough HT voltage. The problem is that LPG needs more voltage for a given gap size so opening it will compound the problem if the coil is not able to produce enough voltage for a standard plug gap, hence closing it up will help if it's failing to produce a spark at all due to low HT volts.

mine only hesitates when i slam my foot down from idle, if i introduce the power slowly and pull away smoothly then it is fine.

I think this is either mapping or the acceleration enrichment for petrol is just not quite right for gas. Former can be fixed, the latter is not so easy. Also, with the 2.5mm jets the fuel was flat out at full throttle so add acceleration enrichment to it and they may simply not be able to provide enough fuel for a rapid transition from no throttle to full throttle.

Yes fair point for petrol.....but a smaller spark may not be enough to ignite the lpg  :-/

  Glad to hear it.

Agreed. Depends what the issue is, really. I guess a bit of experimentation is required.

filled up tonight, 60l    (£30   )

may not seem like too much of an issue but i have a 70l tank and i am only supposed to be able to fill it to 80% of its capacity....and it had some gas in it.....

I reckon the 80% doofer has failed and is now allowing me to fill right up, what are the issues with this?

[Kevin Wood]

what are the issues with this?

Just be a bit careful of filling it up and then immediately leaving it in the sun (some hope!). The tank can overpressure as the fuel expands whereby it vents some fuel to the atmosphere. Not a potential bomb or anything, just a waste of fuel.

If you fill it up and then immediately burn off the extra it won't do any harm. Might as well make use of the extra capacity.

Exactly the advice i was given by lpg installer, when the tank went like on the VeccyC.......no big issue.
And i enjoyed the extra capacity from it  

Tho if the kit is under warranty......would be worth getting it swapped over.

[The Cambelt Kid]

WOW guys, i leave you all for a few months and come back to LPG mania....  

Since i did my install i have never felt happier and my bank manager is chuffed to bits too, so glad others are following suit.  Just a shame i wasn't on OOF to lend a hand here and there.

keep it up chaps  

[JamesV6CDX]

I know of at least 5 of us now that have used DIY kits

[The Cambelt Kid]

That's good to hear.  I've done my second now and am v happy but i think i'm going to keep this car for a long while to get my money's worth out of it.  Doing the install is easy(ish) but it was a pain when i could only do the work at the w/end and had to make sure it was roadworthy the next day for work (or shipping the mrs to the shops!)

The car is a 52 MV6 with 64k for £2800 and the kit cost £700, so not too much money for a cheap, strong, safe family run about!  I'd be happy to keep her for a few years to come, it looks smart and i'm happy to be an Omega owner.

Anyway... i've drunk too much sambuca and am waffaling on a bit now!

Was it you who posted a picture of a very nice job done on positioning the LPG injectors just next to the petrol injectors a while back?

If so, can you dig it up again, please?

Kevin

Kevin,

I'm not too sure if you are after the injector assy or injector nozzles into the inlet bridge.  I've dug them all up for you anyway.
