Title: Another LPG question !
Post by: albitz on 08 February 2011, 15:03:02
The gauge on the tank itself works the wrong way round - ie shows full when empty and vice versa. Not a huge problem, just slightly annoying. Is this an easy fix. :-/

I seem to remember looking at this with JCB and decided that as the level lights on the switch were working pretty well we'd leave it be ::)

Not just a matter of swapping two wires around then ? ;D
I will leave it then, as said it isnt really a problem, just nice to have everything right - if its reasonably possible to do so. :y

I was surprised how basic the actual gauge was, almost like a toilet ball-cock design

It can't have been fitted up side down, as the feed pickup would be as wrong well  ;D

Yes it can... It's only the gauge that's wrong, a separate item ;)

You're thinking of the whole multivalve ;)

I think that's exactly what has been done but, from memory, there was a reason why we didn't turn it the right way around (or perhaps we tried it  :-/)

Anyway... Fact is, the level lights work OK and you'd need to adjust the settings if it was swapped round/replaced so best left alone IMO :y

Perhaps we'll have a chance to look again at some point in the future Albs :y

Some gauges have increasing resistance as the level increases, and some have decreasing resistance as the level increases. Sounds like the ECU is configured for the wrong type of gauge sender to me.

If that's a Stag system (have a feeling it is for some reason) it's just a matter of swapping a parameter in the configuration software.

If not, you need the software and lead, etc... ::)

Kevin

EDIT: Just re-read and it sounds like someone has fitted it upside down then used the software to compensate. ::)

Probably better to let sleeping dogs lie.

IIRCC that's exactly what was done ::)

It is a Stag kit, Professionally fitted and certified :-X :-X :-X

The bloke who did the coolant plumbing should have been certified. ::) :D ;D ;D

It runs OK but... :-X :-X :-X

It's safe now, since I replaced the leaking injector pipes :-X :-X

I'm amazed at how well it runs on LPG TBH as the reducer is right on its limits ::) And the injectors are quite noisy, but all safe and does run well :y :y

Still a little untidy mind ::) ::)

D'oh, of course I remember it just being one whole unit and the "ball-cock" tip valve for filling was part of it. With the pickup, it could only go one way (well if you wanted to use 95% of the fuel  ;D)

Not quite as untidy as it was, but still needs a good sort out.
I moved the ECU from its home - jammed between the coolant tank and the air filter, which allowed the air filter to go back onto its mountings. It now sits under the airbox on the chassis rail, and fairly close to the fanimold, which probably isnt the best place for it. ::)
As for the plumbing............................ :-X, It does seem to run ok though, although it rarely goes over 3k revs anyway.

3000 RPM on a V6 is still equivalent to 4,500 RPM for a 4 pot. ;)

If I push it as hard as I do in a 140bhp 4 pot, it won't hang about with 400 bhp!  :D

You remind me of a quote I read the other day - in an article detailing the build of a ~550hp Dax 427:

I'm proud to say, however, on a quiet B road in Wiltshire there is a 50 foot long number 11, and I'm responsible....

I was sold at that point.  ;D

Yes, I had a ride in one of their demonstrators a few years. back. "Interesting"  :o

I see they have got a 502 in their latest incarnation. Same engine as we use in the winches at the gliding club. I bet it's a bit of a handful in the wetdry. ;)

I'll bet they are!

I've been doing a bit of research into the various kits recently with the aim of building one later this year & next (to coincide with a friends 40th for which the plan is for the three of us to drive to Monaco - one will be in his Porsche, the birthday boy plans to have a Ferrari 355 by then since they're at rock bottom prices, anyway) - I'm glad this forum isn't like cobraclub.com though .. I'm still waiting for the 'moderators' to activate my account so I can do more than read posts  ;D ;D

Well, I can recommend it. ;) A mate of mine built a Tojeiro many years back. Just had a lightly breathed-on Rover V8 in it so not fast by any means, but it had the most lovely-sounding pair of sidepipes I have ever heard.  :-*

It's what got me interested in building a Westfield. Did a memorable journey down to Le Mans and back in convoy before I'd even ironed out the teething problems on the Westfield. ;D

The tunnels were the best bits. 8-)
