I have created this as i didn't want to hijack James's thread about his LPG conversion, however having read it it got me thinking about saving some money.
Friend of mine owns a garage and was looking into this, we are looking at using my Omega as the mule to suss out how difficult it is....
from my point of view i have a couple of Q's
There seem to be a few kits on the market, 'mixer' and 'sequential' seem to be the most common, am i right in thinking this is the same as single or multi point injection on cars?
Are there any kits/maunfacturers that offer better after care than others, this is a very subjective question but again i am just trying to avout some of the pitfalls.
Testing, how do i find out who can test a DIY fitted system? is there the equivilent of the CORGI register for LPG fitters?
finally i have been looking on flea bay for an idea of price and saw this
http://cgi.ebay.co.uk/5-6-cyl-Conventional-Mixer-Autogas-Lpg-Conversion-Kit_W0QQitemZ220107359809QQihZ012QQcategoryZ36631QQtcZphotoQQcmdZViewItem
any views?
-
Sequential kits are better......they squirt the gas into the intake of each cylinder.
Mixer systems, i think, just squirt the gas into the throttle body.
Any LPGA fitter can certify the diy installation. In theory how it works.....is after the lpga fitter gives you certificate.....he passes on your details to the lpga, who can contact you to come and assess the install and if its not upto standard, the lpga fitter who gave you the cert is in trouble.
Have a look here, if you havent already, might give you some more info :y

:y cheers for the link....
i'm witing for the seller to come back to me on a cost for a sequential kit as well, have a feeling that will be a lot dearer....
If i could keep the cost the right side of £700 all in i would be happy
Is there a Road tax benefit to having LPG?
-
No you cant get any money of the road tax >:( which i think is really bad
-
Definitely sequential system.
Before I do a bit search on that subject.
BRC kits here is #1 (most expensive but deserve the money)
Landi is #2
In my opinion LPG fitting musn't be done as DIY (may be will be opposed).Being an enginner I dont accept any amateur work on that subject.
But before you must be sure your car dont have any problem.Thats very important. Otherwise things will really mess up.
Better let it for professionals who do it everyday..Choose a big garage..Ask the project for your car..Ask the money.Ask the warranty.
See examples they have done..And watch them closely when they do the job..
Very serious subject..

Let the professionals cock it up :(
Let them route the harness next to the EGR so it blows the DIS pack, let them put the ECU in the airbox
let them try 15 different ways of connecting the evaporator until it works.
Hmm think I'll pass

thanks for the tip on sequential systems
Anything to do with my car is serious, i rely on it so much.
The garage i used is a small one, he is a very good personal friend and has many years experience in the motor trade, he is qualified and has spent a lot of time training apprentices, he knows his cars and the work he does is far from amature.
We are in the process of investigating the difficulties of an LPG kit, on face value there dont seem to be that many, those items that have been established as risks are being properly looked into in order to be sure we have an acceptable and safe solution.
The car has a lot of mileage on it, over 200,000kms/140,000 miles but it is serviced almost monthly, the plugs, leads and dispack were changed a few months ago, the next job will be the breathers and rocker covers at the same time as the conversion takes place.
and whilst i am not a qualitfied engineer i have completed several groud up brbuilds of cars and am very compitent with the understandings of an engine and fuel system

I tought things were different in England :o
These things you tell is really amateur job..
But I'm really sure there are real proffesionals ..Also in this group is too many..

He was actually quite well rated and has done good jobs on Jaguars, but he messed up quite a bit on my last car.

It's always the same. Someone gets a good name for doing a good job, ends up with more demand than he can cope with, so recruits some knuckle draggers to do the work while he "supervises".

Thats exactly the same case here..
I'm a member of local lpg sites and I know many problems for incorrect fittings ,problems together customers,
many complaints ,damaged ECU units,MAFs etc.
Ps: forgot to add I was very close to go in court with a local branch who damaged the friends car..

In my opinion LPG fitting musn't be done as DIY
Being an enginner I dont accept any amateur work on that subject.
I disagree, as long as the LPG install is certified by an LPGA approved centre before going on the road I can't see an issue. Most people doing a DIY job will want it to be a good one and hence take extra care.
That's like saying only a professional garage should change a wheel bearing, in case a wheel falls off if an ameteur fits it...

Hear Hear! There's too much talk of WHO can do what these days. My father has a degree in Electrical and Electronic engineering from one of the top universities, he's a Chartered Engineer, a fellow of the Institute of Electrical Engineers (or whatever it's called nowadays) and spent his career in the electrical / electronics industry. Yet he can't do simple wiring in his own house.
It's the standard to which the job is completed that matters, not who did it.
The rush to have registered people to do X,Y and Z is the result of lobbying by trade associations who like to create work for their members, IMHO. It must be stopped before we are not allowed to lift the bonnets of our cars any more (let alone build a kit car, for example).

The IEE is now known as the Institute for Engineering and Technology :y
I completely agree. This whole LPGA approved nonsense is all about making money and very little about improving safety. They are a self-appointed group with absolutely no regulation whatsoever, and I have heard plenty of horror stories of "LPGA approved" installations that were unreliable, poorly fitted, and even some that were considered unsafe. I have an LPGA certificate for the dual-fuel system in my car (which was fitted before I bought it) but that made no difference to my opinion of the car or dual-fuel system until I'd had a good look at the install myself. All I'm saying is that LPGA approved is meaningless, judge only on the quality of work and reputation for after-sales service. The only way is to ask around (try some online forums) as get as many opinions as you can.

Completing one job in a proper way is a matter of knowledge,practice and necessary equipment.
if you think you or someone who have all of those complete (this means profession) then can DIY.

found a kit on flea bay
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=330170356040&sspagename=ADME:X:RTQ:UK:11
been chatting for the seller he knows his stuff for the SGi kit and 70 litre tank as well as software and leads, he was really helpful and has answered loads of stupid questions about the kit and installation
All in less than £700!!
Will be placing my order next week once i get paid

That's also the kit I've been looking at ::)
Seller is a very good bloke, thankfully they are in plentiful supply!
-
seems to be a proper kit..and a high safety tank will be a good plus..
-
may be good idea to ask price drop for 2 installations :)
-
.. or three? :-/
Kevin
-
Or four...
-
He's only 40 mins drive from me too. :-/
Kevin
-
I have another idea..Forget the price drop..Choose one "lucky" person..He tries first..See what happens. After everybody will follow..
So who's gonna be the "lucky" man..
ps :shortest stick method can work also for the lucky man... :)
-
it will be me then, i have placed an order.......
However work have just let me know i am now fully booked until Xmas......i shouldn't moan but that is going to cost me a fortune as i wanted to take a week off to do the install >:(
-
Congrats for the voluntary "lucky man" :y
You are a pioneer ..!!
-
you know some people make it groups..In round robin style..every month one take the money the others give..
In case you make 3 or 4 will be like you pay in serials...
-
I think this is the F/E James in interested in.
Be interesting to see how it goes

Possibly do yours/my installations together? Maybe see if Martin is free to come down also?
I have some spare inlets we can drill, to keep the cars mobile...

Cheers for the offer James, Mark has kindly donated one, just got to wait for him to get back from India to pick it up

Jay - what size and pitch of thread are the injectors? What size drill bit and tap are you using?
-
I'd suggest you get a lot of jobs done while the plenum is off - rather than pop it on and off like I did!
So
1) Fit the evaporator supply pipe and T pieces at the back of the engine.
2) Fit the injector nozzles and rubber pipes - remember to block them with something (injectors will do)
3) Fit the cut injector cables - but this requires the ECU to be fitted.
So fittng the ECU and loom is near the beginning.
If you want to do the thermostat, cam cover gaskets, oil cooler - good time is when it is in bits.
-
Jay - what size and pitch of thread are the injectors? What size drill bit and tap are you using?
They may not be in the kit, he may not have the kit yet anyway, but M8 (6.5mm drill) is a good guess
-
sorry but after the installation dont you need manual arrangements in LPG ECU (of course with a laptop or pc) for better mixtures

Via a cable - the ECU can be anywhere - there is a plug on the loom to connect to a PC

Surely the front end kit comes with injectors!!

Injectors are NOT mounted directly on the manifold
Remembr mine, plastic injectors on a short hose onto plenum mounted nozzles.
Nozzles need fitting, not injectors.
Nozzles may not be supplied as they would be different for different applications - eg I have long ones which go through the plenum. Whereas a lot go into the manifold.
-
Would you recommend going through plenum.. or would you go directly into the manifold near the valves as possible?

WHen cleaning breathers - into manifold, when fitting - into plenum.
I don't think there is too much difference but into the manifold is neater

Whoa! some catching up to do. Soulds like a plan! Would certainly be good to get a couple of manifolds modified for the nozzles. Is the manifold the same across all models?
Might be worth seeing how Jay W's kit pans out- or at least wait for it to arrive and see what it looks like.
I'm also concerned about getting the installs certified and I don't want to end up with a liability with respect to getting insured. Has anyone determined if the seller can do this or are there any other ideas on this?
Cheers,
Kevin

i fitted the nozzles alongside the original injectors, m6 thread

i haven't got the kit yet, as soon as i do there will be a load of pics posted up with the outline of what is in the kit.
Being sent by parcelforce, are they affected by the strike?

Not sure but these go through the plenum

have been told it will be here today, there has been a huge delay, looking at the tracking details it wasnt the chaps fault either........
As soon as it arrives i will get some piccys up, have been told it comes complete with nozzels as well, the ony thing i will need will be tools
-
Good luck
Are the nozzles the correct internal diameter or will they need drilling?

Do the nozzles on an SGI setup need sizing for the engine?
Just thinking as the flow rate for petrol injectors has to be reasonably closely matched to the engine's fuel demand so you've got sufficient fuel flow for peak power but not so much that resolution suffers at idle. I guess it's the same if you're injecting gas but kits I've seen just say "good for up to x BHP".
Anyway, hope the conversion goes well, Jay W. Keep us updated :y

Some do - seen that OMVL ones need sizing
-
the supplier has said that they are good for up to 200bhp, after that they will cause lean off, the software that comes with the kit will help me to set it up so it runs at optimum, if i do need different injectors then he can supply
-
May be a little marginal for my 3.2 then :-/
Still, have established contact with the guy and he seems helpful.

I would think it would be fine unless you wanted to really give it some large... in which case I suspect you'd want to be running on petrol anyway!
-

They may not be in the kit, he may not have the kit yet anyway, but M8 (6.5mm drill) is a good guess
Careful...It should be a 6.8mm drill. You might break your tap which would be a REAL pain to get out.
Great thread...keep it going. I am planning on gassing up my 3.0 in the next couple of months (diy job).

really disaapointed as the kit didnt turn up today, delivery van broke down >:(

Yeah, but running engines lean at wide open throttle is not good, and remembering to switch to petrol when the red mist descends is not going to happen ;D.
Will ask the chap what he reckons. I guess given the power drop on LPG it'll be around the 200 BHP mark anyway.
I could dust off my wideband lambda sensor to set it up, I guess. :-/ Anyone got an old Lambda sensor that I can butcher for the connector to wire it up?

Hopefully it'll arrive tomorrow then you can play at the weekend :y

well the plan is to make this look as factory fit under the bonnet as possible, i have never seen a dual fuel V6 but i want everything to look like it should have been there.
Because of this, the fact that i work away from home so much and that this is my first LPG install it will be done in stages, we will be doing the Back end first (tank, nozzle and plumbing) followed by the electrical stuff (ECU, loom, switch) next the Vapouriser and water hoses the inlet and plumbing and finally connect the front to back.
I have got a spare manuifold that i have to collect next week, this should save us some time when we cme to that stage, thanks Mark DTM :y likewise if all goes well and i have mine going spare then i will offer that up as a spare so someone else can have the same luxuary as me.
Once we start i will start a new thread and try and keep it as updated as possible

Which plumbing - you can't do the plumbing until you know where to out the evaporator
-
i attacked it from the opposite end engine and ecu first tank later.as a minor point i fitted a tank in the spare wheel space which worked well despite issues with the light cluster.trouble was it only carried 41 litres which gave it a range of 220 miles(cruising)so im now in the process of fitting a 100 litre tank across the rear seats which should double its range( live and learn) :)

Evaporator - on the inner drivers side wing, bolted through wheelarch seems ideal - right below header tank too, and sams side as matrix pipes, so great for coolant flow.

Sorry Martin, i meant a factory V6.
Having seen yours i realised it wasnt rocket science and decided to take the plunge
Which plumbing - you can't do the plumbing until you know where to out the evaporator
The evap will go under the header tank, as James has suggested, saw it on Tunnies and it looked an ideal place with about the best access you can get on a V6.
That said i have most likely forgotten/overlooked something and am always open to suggestions

Is that the biggest tank that would have gone in the spare wheel well? Just wondering about tank options. Don't suppose you've got the vertical doughnut tank for sale? Not sure if 220 miles would be enough although I like the idea of not losing the boot space :-/
There is an LPG garage a mile away from work so it may not be so bad.
With the bigger tank is there any prospect of folding down the rear seats and fitting any long objects in the car or does it cover the rear seat aperture completely? Just thinking about when I have to go and buy long bits of wood, etc.... :-/

Kevin

My tank only holds 38L and gives a range of between 125-200ish miles......is a bit of a pain coz i need to fill up everyday and sometimes run out of lpg.....but i put up with it coz i dont lose hardly any boot space :y
-
tank is supposed to have a capacity of 63 litres but will only fill to 80% running around town the tanks range reduces to approx 165 miles

For some things yes, I have a 3 inch or so gap - however for long pieces of wood a roof rack works better

Thanks for your input, guys. Hmmm :-/ Decisions...

Well, I will be going for the bigger tank and live with the smaller boot. I do 100 miles/day. Anyway, I've got roof bars ;).

Mine is 100L (carries 80L of LPG) which I think is the biggest you can fit in there, it's pretty close to both the wheel arches on the sides and the parcel shelf at the top. No chance of using the boot aperture. Personally I much prefer it like this, not sure what it's like down south but here the availability of stations isn't great. My boot is empty 99% of the time, apart from when going snowboarding with my mates or going on an inter-city partying trip. Both times there's still plenty of room as it's mostly clothes (and in the latter case beer) in there. I have a pair of quick-detach VX roof bars for the snowboards.

That is where mine is located, and I had a similar issue with it being mounted where the cruise module was to be installed when I decided to add cruise. Took a bit of extra effort but I got it in there without disconnecting the gas or water pipes, had to move the aux pump but that was an easy enough job as there's a fair bit of slack in the pipes.

I would think it would be fine unless you wanted to really give it some large... in which case I suspect you'd want to be running on petrol anyway!
Personally I would err on the side of caution with this, you'll end up melting a valve or similar if it is allowed to run lean for any length of time. The way mine is set up I can bounce it off the rev limiter before shifting up and there is no discernible difference compared to petrol. I'm sure there is a small measurable difference, but it's close enough that I don't notice. I do flick back to petrol when I really want to wring out that last few BHP but that's pretty rare.
I should add that if you're setting it up with an AFR on the wideband lambda it shouldn't be so much of a worry, as you can bounce it off the limiter with the foot on the floor in say 3rd gear, and if it doesn't go lean with the right mapping under those circumstances it'll be fine.

tank is supposed to have a capacity of 63 litres but will only fill to 80% running around town the tanks range reduces to approx 165 miles
You'll have to hope the level valve becomes sticky :y
My ex veccyC had a sticky valve and 50% of the time would let you fill the tank 100% 8-)
I was a tad concerned about this to start with......so i visited an lpga installer and told them the prob.....they said if i really wanted they could change the tank......but apparently it wasnt really a problem.......unless you parked the car on a hot day in the sun just after 100% filling the tank......then they said all that would happen was....if the gas expanded too much....was a big hiss as the pressure relief valve opened releasing some of the lpg to get the pressure down.

You're right that running lean is bad news, especially in a heavy car like an Omega which can put a lot of load on the engine for long periods of time. Anywhere else on the map you can do what you like to the mixture without killing the engine if you're sensible but if you're going to have your foot hard down for more than a few seconds you need to see a comfortably rich mixture as that will keep the temperatures down.
If you hit the rev limiter the wideband reading will go all over the place as the ECU cuts the injectors, but I mapped my Westfield on public roads using a WB and it was a piece of cake. You could accelerate with the hammer down, watching the RPM and lambda and make a mental note of what needs adjusting at what RPM. If it goes lean come off the gas and add fuel. Tweak it with a laptop and repeat. Plenty of time to take it all in with just under 200 BHP in a 650 kg car, so an Omega should be ok :y
You can of course datalog it and then look through the logs but I found doing it by eye easier, with a laptop on the passenger seat to tweak the map.

still not here and I am livid with the courier...they are so busy cos of the royal mail strike they can't keep up
the software that comes with the kit allows you to datalog and take snapshots that can be saved for reference and tuning, this is one of the things that swung it for me.
one query I have got, part of the wiring involves connecting up to the lambda, do I break into both or one? I'm worried if I only do one and that bank is reading differently for some reason the other bank will be adversly affected.
-
I guess the Lambda depends on whether the SGI system had dual lambda inputs. If it's only got one you've just got to connect it to one of the sensors. There shouldn't be a huge imbalance between the two banks.
I assume it probably only needs the Lambda input for initial calibration / automatic mapping. Once it's set up the injector durations should follow the injector outputs from the OEM ECU so you will effectively be running the lambda corrections from the 2 banks independantly.

Good news....
The front end has arrived, it transpires the seller gets the goods sent direct froom his supplier, tank should be here next week.
The front end kit is where all the Q's were and looking through the instructions has answered them.
There is a second take off for dual lambda cars, this will give an accurate reading.
I am going to start a thread on the install, starting with the pics of the kit itself and contents
