Personally, if I were to convert again I'd probably go for a 80L single hole tank for the best compromise

Hmmm, I'm contemplating my next one being 4 hole  :-/

Probably advisable as it's a 3.2, although Chris' pressure wasn't dropping off at full chat so the high flow multivalve should be plenty man enough :-/

Though he seems to suffer lag worse than the rest of us, unless he's a whinging sod

Well, erm..

Not convinced the lag is related to anything as far back in the system as the tank valve. I think the gas ECU gets confused by something the engine ECU does and loses sync for a couple of engine cycles. Then again, mine isn't too bad. Occasionally it gives you a jolt just to remind you it's still there.

The thing which has me most confused over it is that there is no lag whatsoever if you hold the pedal to the floor right up to the red line... In any gear I even felt the need to test this again tonight on the way home from work when some c0ck in an Audi was bugging me somewhat with his crap driving

LPG injectors are probably fully open by then. In fact, those injectors are pretty slow in terms of open/close time so they will probably ride out the odd glitch.

It really would be good to investigate a bit further but need some better data acquisition than a 'scope in the passenger footwell.

Need something which reacts more quickly than the software as it's too slow.

Think I'm going to try and pin Teilo down again and visit him so he can try curing it... I reckon the problem is the injectors, he reckons that it might be the diaphragm in the Vaporiser not reacting quickly enough if he can't tune it out.

Time I got him to put his money where his mouth is I think

[Lazydocker]

To be fair, I rarely notice the lag any more as I'm used to lifting just before the gear change if "in the zone" or take it right to the redline

Mine only lags at redline. Perfect the rest of the time, truely perfect.

Looking at a prins system personally, expensive, but local installer won't use anything else purely due to the injectors, kehins just work he said, we get aggro with all the others.

It maybe that he can make more on a prins, which might explain his refusal to fit anything else now. But I get the feeling prins is issue free....it may be that he can make more on a prins due to ease of set up and less rather about with gremlins. He also mentioned the prins works better with seasonal changes. Got the feeling mine needed re calibration on the average ambient temp to keep the lag at bay as much as possible.

I did ask of the prins kehin injectors could be used on any other kit. But who knows what signal they run off, and will the drivers(?) fail after a while if not totally happy?

Patrick at the place in Alresford where Entwood got his conversion raved about Keihin injectors too.

There are plenty of injector settings on the Stag ECU. I'm sure one of them will work.

Having said that, with the number of Stag systems we as a forum are running, there certainly doesn't appear to be an issue with reliability of any of the kit, injectors included. They are just rather slow, which may or may not explain the problem. (I have seen other systems with equally clunky injectors work fine)

From the point of view of an installer, why would you support multiple systems? Find one that works for you and stick with it. It also means that you'll be putting more business with a single supplier so can probably get a better deal.

.. especially considering UKLPG and the manufacturers are a bit anal about going on a course for every kit, when in reality they are exactly the same beast so if you're competent at fitting one, you can fit them all.

All makes sense, but they have numerous customers of varying budget, not all want to pay top whack for a gremlin free kit. They fitted stag brc in the past and numerous others to suit the customers pocket/fussiness. From what he tells me some LPG customers don't care how they arrive, or even if they arrive as long as it's cheap, going by his report on some of the test drives he's done.

Certainly the stag kit components are reliable in that they don't break. Fact is we all have a lag issue of some sort with a v engine. I'll not be buying another until a solution is found personally. Shame.

Although, didn't LD have an ecu fail?

Was a fuse in the end IIRC. I think somebody had an injector fail, and somebody else a vap. temperature sensor but that's all I am aware of.

Thing is: how much cheaper is a Stag kit once you are having it professionally fitted? Probably not that significant when the labour is added.

So it sounds like a single hole 90L is about the right choice for me had a look on the tinleytech site and it only shows them without the valve unlike the fourhole.

Stupid question time where do i buy the valve from can't see it on their site??

How much pipe do i need from them or is there a kit that supplys it all, as mentioned i will be buying it bit by bit over the next month.

Stag front end kit seems to be the way forward from what everyone is saying

Tunnie will probably take you up on the manifold, who is it that does the drilling and tapping again??

Dave, imho it would be much better to wait until you have the money to hand & get the full kit in one go from Teilo. Everything you need is there & you only need to specify which tank size you want. As for drilling & tapping the Manifold, if you can drill a hole in a piece of metal, you are capable of doing it yourself, it only takes a 1/2 hour! You can fit the back end (tank, valve, piping & wiring) easily in a day weather permitting. My system cost me £495 earlier in the year.

Thing is, do Prins, BRC etc suffer issues with the lag?  Certainly my lag only shows up (and not all the time), when ragging the tits off it.

I reckon - though not tried - I could completely eliminate my lag by switching to petrol at around 6500rpm, and ensuring that it ran on petrol for a minimum of 2 or 3s.

My lag is more prevalent at the 2nd to 3rd and the 3rd to 4th gearchanges (and only if it redlines), and occurs immediately after the gearchange.  How many people drive like that? I certainly don't often enough to annoy me, else I would have done something about it.

I'm tempted to go with the Stag, mainly due to the knowledge on here, and then both Omegas also run similar systems,
