PLEASE look at the last couple of posts on the last page of this thread...

Where are all the questions

[Gilbertd]

Nobody dare ask any in case they get a lecture.....

[scottyf]

Maybe everyones lpg systems are working well.
id still like to tune mine a bit better. But for now its working well. One of the only things that is wofking well on my heap of poo car.

Where are all the questions

why don't we see white dog poo anymore?

[Tubbs]

Why is the word 'abbreviation' so long ?

Because dogs have better diets nowadays.

i was told its cause they can't have bones from the butchers?

[Tubbs]

Still no one has managed to answer why abbreviation is such a long word for what is essentially shortening something ?

[john_d]

abbreviation is abbreviated

[minimutly]

Come on then tubbs, your opinion on why my daughters 1.8turbo mgzt drives so badly.( Aeb)
On petrol it's horribly weak, until on boost, then it's fine.
On gas it was horribly rich, but not enough to cause a misfire.
Would running on gas cause the fuel trims to go so weak? I have disconnected the batter and there is a slight improvement, but how long would it take running on petrol to relearn the fueling?
On gas, the reducer adjustment doesn't seem to do much, presumably I need a new one?
What should the gas times need to look like - I know it varies on what nozzles etc, but is there a ballpark figure? I think they were, and still are on 18 ms max
And the big one, which Tilley tech have answered, but I'd like your opinion also, why would the ecu just ramp up and up the gas on an autocal?

What I've now done is to adjust the left hand column to the side of the map to get closer to what the lambda says I want, for example the 1st "line" is now 4ms, and it's still slightly weak - but then it needs to be, to get the petrol corrections to go the right way.
I've gone up in steps from 4 to 18.
Thanks in advance,
Huw

You've already started a thread on the MGZT Mutly Been a few recent answers...

[mondeoman]

OK, I'll chip in with an easy one, you are all, fully aware I'm sure of my done in a day conversion which I recently serviced, (it's a little over a year old now). All is well but my question is this ....

When it was fitted the need was to keep costs to a minimum, though I upgraded most things from the bare minimum so the ECU is the Stag OBD version, reducer is a Tomasetto Artic and Injectors OMVL. The whole extra cost was about £50 most of which was the ECU.

Now I have saved all those thousands of pounds from not buying Petrol and subsidisng the Chancellors Christmas Party fund would I benefit from upgrading anything. I'm not really into changing the ECU, I don't think it's worth changing the reducer so basically it's injectors, would it pay me to upgrade them, bearing in mind the old saying, "if it ain't broke" etc.

The other thing I would like to do is swap out the venturi based valve saver for an electronic one. Which is best, and is a four way splitter to inject each cylinder beneficial?

[LPGC]

Had a quick look Paul, can't find or remember which vehicle you DIY converted - probably a brain lapse lol...
Not much point to changing anything on the fueling side of the LPG system, if your components allow correct tuning and you've got it tuned correctly then you're not going to see mpg or performance gains by fitting different components.

Advise on whether to change the lube system would depend on the vehicle... For many applications I have more faith that lube will be shared equally between cylinders with a common entry point (near the throttle body) than with a multipoint lube setup. My thinking - If the lube does it's job it should atomise in the airflow and be carried to each cylinder equally (with the air, like petrol from a carb) but it's anyone's guess if liquid lube in pipes exits each of the multipoints equally. Because of that view, I only fit mutlipoint lubes on engines that have manifolds with sumps etc where lube might drop out of the airflow and collect in the manifold, but other installers have different opinions...

Whether there is much advantage to an electronic lube over a vacuum lube will also depend on the vehicle and driving norms (e.g. sat on the motorway at 70 in some vehicles sees a fair bit of manifold vacuum, in others (say a small engine'd vehicle with a CVT auto) there's nearly no manifold vacuum except at idle - If I had a vacuum lube and found the level was going down fairly consistently regardless of the type of driving I was doing then I'd have no concerns... Unless it was booted often...

[mondeoman]

Thank you Simon. I forgot to add into my post that you are meant to be Pshycic! Vehicle is a Honda CR-v. Lube bottle works but is a bit inconsistent. To my way of thinking it is mounted a bit high, however it is hard to see where else it might be fitted whilst still allowing access to top it up.

The single nozzle is drilled between the throttle body and the inlet manifold and has a good vacuum.

[LPGC]

Sorry for the late reply, would guess you've decided what to do regards this already by now, but anyway...
As memory serves, the Honda engine doesn't have a 'sump' of any sorts, so personally I'd probably be happy with the single entry lube... Probably, because you say the lube usage is inconsistent - would depend on those inconsistencies,. You could maybe see what manifold pressure you run at on the motorway / around town and make your own mind up. I think an auto CRV will have less vacuum on the motorway than a manual.
Wouldn't worry about the height of the lube bottle, worst that could happen is that with too high a bottle the lube could be siphoned into the engine when it isn't running... I've never known that to happen...

I had forgotten about Mondeoman's question on this thread (which I've just replied rather late to), haven't been on the forum for a while.

Re-visited this thread to say that the forum still seems slow... and to suggest maybe fewer people are asking about converting to LPG due to the recent lower fuel prices.

Maybe people think they're quids in now petrol is a bit cheaper? Still, must say such a view to me seems a bit daft - Ahh, petrol is only £1.25 a litre now, so no need to convert my vehicle to run on LPG which is only 61p per litre.. (figures based on recent Fleetnews.co.uk fuel prices for Leeds).

Here's a thought... I wonder how much people wouldn't mind paying, upfront, if they thought the payment would mean they could buy petrol or diesel at half price in future for their vehicle... (a) In the case of a one year deal? / (b) In the case of a forever deal? Reckon there would be a great many people willing to pay almost all of their annual fuel bill upfront in order to save (a) just a few quid at the end of the year / (b) some people would be willing to pay tens of thousands of pounds for the forever deal.

We in this trade convert vehicles to LPG, which offers half price fuel for that vehicle basically for ever and adds value to the vehicle, for a one off fee, - and for less than people would be willing to shell out up front in order to get half price fuel for less than one year, but our solution offers half price fuel for that vehicle for ever....

Yet when we see a few pence knocked off a litre of petrol, this industry slows down quite a lot - This implies that most people are not wised up about LPG, or maybe that most people are prepared to follow the herd and pay up... including clever people that think they go out of their way to get good deals

I haven't posted on the 'UKLPG comments' thread that I started for a while (neither have I spent much time on the forum lately). But here's something related at least in part - We in this trade would really benefit from something that promoted this industry by raising awareness, UKLPG arguably don't do that (and in any case would only be willing to promote their members).

How about seeing how much it would cost for some kind of national advertising campaign, compiling a list of interested installers, when the list is compiled count the number of interested installers and ask each interested party to pay their share of the cost... The advertising campaign would point to a website that contained the list of installers who had paid, so any newly aware customer would look at the website and find their nearest installer. Depending on the number of installers that paid, the campaign could be geared up / down or cancelled based on a final vote, in the event it was cancelled any money paid in would need to be returned. Not quite as simple when the practicalities are considered, but who likes the idea?

[scottyf]

But its really not that simple is it.

With that extra £1000 they could buy a more fuel efficient reliable car.
What happens if that car gets wrote off

There's much more than just the cost of conversion and that'll be half price fuel forever.
They do less mpg, There are less filling stations. Tank range is less (Generally unless you give up space in most cases). You have less power generally as a rule of thumb.

Its not as simple as what you've described.

[LPGC]

Agreed won't suit everyone Scotty, but would suit a lot of people.. Having converted your (Alfa?) to LPG, you're at least in part pro LPG.. You didn't sell the Alfa and buy one a bit newer, or a diesel Alfa..

In most cases at least the engine conversion components can be removed / refitted to the next vehicle the customer buys, reducing the cost of converting their next vehicle if the owner chooses to have the system removed from their existing vehicle (especially if scrapping the car etc).. But in most cases the system will have paid for itself in a year anyway.

Petrol has dropped to £1.21 last week at most garages around my area. And this morning gone back up to £1.26.9.
Don't forget it's also christmas and having there car LPG converted is the least of there worries now.

Do you not find it fluctuates after the christmas period?

I also have a question: The inlet manifold on a 02 1.2 corsa, can you put the normal brass spuds in for LPG or do you have to use (The spacers as i call them) Fit between the fuel rail and the petrol injector. As it has the air flap in the manifold?
