After a few false starts, Bl**dy H*ll, what do I do with this moments, I have finally got my car running well on LPG. I started with a 2nd hand kit, well at £100 for the front end it looked good. :P
I pretty much followed the layout in the guide, with a few mods and tweaks.
I put the ECU under the front offside like many others, it makes sense there isn't much space else where (http://i159.photobucket.com/albums/t155/lapbits/PICT4577.jpg) OK the bracket is a bit OTT, but there is no chance of them saying its not adequately supported.
(http://i159.photobucket.com/albums/t155/lapbits/PICT4586.jpg)
I then divided the cables into 3 runs, 1 for vap, rear end, and control, 1 for injectors and 1 to the main ECU, each in trunking. It makes it easier to feed and mount and is, I think, kinder to the wires, they are not pinched tight in a cable tie. There didn't seem to be enough cable to feed from the rear of the engine, so I fed the injector lines up the front with plenty slack, which should make cambelt changes easy, just move the trunking. (http://i159.photobucket.com/albums/t155/lapbits/PICT4599.jpg)
I was lucky and was able to tuck all connectors around the inlet manifold without taking out the existing cable tray, (http://i159.photobucket.com/albums/t155/lapbits/PICT4601.jpg) and with the manifold back (http://i159.photobucket.com/albums/t155/lapbits/PICT4598.jpg)
The rest proceeded as in the guide, I moved my 90L tank over to the offside as far as poss, so I could still get to the boot release handle if power failed.
And then fun with the tank valve. I used 8mm polypipe for all liquid plumbing with adaptors, and couldn't get them into the air tight box and valve. It turns out that if the inlet feed is only in 2.5mm ish, the adaptor nut is still inside the air box housing and won't fit into the valve. I had to sink the inlet hole an extra 5mm to get the adaptor in far enough (http://i159.photobucket.com/albums/t155/lapbits/PICT4635.jpg)
And the reason ?. (http://i159.photobucket.com/albums/t155/lapbits/PICT4636.jpg)
As you can see the air box holes and valve pipes don't line up. I guess it would be OK if you were using copper pipe, but a pain if using poly and adaptors.
I decided to put the filler under the number plate, and opted for a top swiveled flap. Reason being I felt it would be a bit more out the way and if I fit a towbar hopefully it will clear the ball.
I made the flap using an electroplated brass hinge and a couple of pieces aluminium pop riveted on., (http://i159.photobucket.com/albums/t155/lapbits/PICT4622.jpg) I then fitted the filler (http://i159.photobucket.com/albums/t155/lapbits/PICT4617.jpg) and then trimmed the the hinge flap around it (http://i159.photobucket.com/albums/t155/lapbits/PICT4644.jpg) and when closed (http://i159.photobucket.com/albums/t155/lapbits/PICT4643mod.jpg) I then connected up the feed pipe and refitted the bumper (http://i159.photobucket.com/albums/t155/lapbits/PICT4623.jpg)
This works fairly well in practise, (http://i159.photobucket.com/albums/t155/lapbits/PICT4649.jpg) (http://i159.photobucket.com/albums/t155/lapbits/PICT4650.jpg) its easy to fit the filler.
I connected all up, laptop plugged in and it all worked. Well sort off. It wouldn't read the petrol injector times :P Occasionally if I changed the injector sense it would flickup a number then go back to zero. I tried all things, it would calibrate (sort of) and run on LPG but flagged up an error. I decided it was a faulty ECU so thanks to LD I contacted Teilo after a couple of days and managed to order a new ECU. Getting hold of him is the problem he is very busy, however when I finally did he was very quick, I order it one day around lunch and it was here the next day. :y
It was about 1/2" shorter than the original so my nice bracket didn't fit, and had to be adjusted. Nothing a big hammer couldn't fix. And I plugged it in and switched on, and ...................

Well done Ken.A very interesting read indeed. :y
-
Thanks Abs, I'll finish it tomorrow :y
Cheers Ken
-
filler under the number plate is really a good idea.. thanks for sharing :y :y
-
Good to see you've finally become a gas sniffer Ken ;D :y
-
How are you keeping the numberplate flap closed (having made one myself, this was a pain (so the 2nd one i bought ;D))?
-
It was designed that way........
er not really, it just happened. The number plate panel is curved, so the hinge doesn't like to be opened, it slightly bends the flaps which tends to return it to the closed position. That and the hinge is crap, it might be brass plated but the rod through it is steel, and has rusted slightly so it tends to stay put. Typical engineering (that's not a bug, that's a feature ). :y

Damn, I thought you'd found away without buggering around with crappy springs.
The MV6 one (the home made one), I have to oil up every 3 or 4 months, but works well. The bought one always snaps shut, but is a PITA in use.

Well done Ken. One more of us, one less of them. So to speak. :)
-
Glad to hear you've finished Ken :y :y
Yep, the loom is too short (in standard form) to run up to the back of the plenum but the last 3 I have been involved with I have modified it with the large Vx Injector plug so it can be done :y Basically you cut off all the Piggy-back plugs and wire in a Vx Larg plug and socket with about 20" of loom on the shortest of the piggy-back plugs... Makes it even tidier :y :y

How about attatching the number plate to a door letter box flap?

Tried that, couldn't get a setup that worked - most of those that don't use brittle plastic torsin springs only open the 'wrong' way.

Thinking of a good old fashioned one, from a demolition dealers.
-
.... that's small enough to clear the filler behind it....?
By the time a letter box has been modified to work, may as well make what's required from scratch, no?
The spring loaded ones designed for the job open 45degrees. Some nibbling away at the parts that hit the spring and restrict movement can improve the opening angle a bit.
I'd work on improving that design as its almost there, personally. It can go either way up.

oh FFS, yes I meant 90 degrees. Sorreeeey.
... well you try watching the footy, keeping the Mrs quiet, playing dots with the cat, and typing on a crapple iPad. I reckon I'm doing bloody well tbh. Being male and all. ;D

My homemade jobbie opens 180 degrees, and unintentionally latches in place.
Shop bought one, nibbled away at, opens perhaps 100-110 degree, and is a PITA. Tempted to bin it, and make another...
