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.
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
OK the bracket is a bit OTT, but there is no chance of them saying its not adequately supported.
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.
I was lucky and was able to tuck all connectors around the inlet manifold without taking out the existing cable tray,
and with the manifold back
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
And the reason ?.
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.,
I then fitted the filler
and then trimmed the the hinge flap around it
and when closed
I then connected up the feed pipe and refitted the bumper
This works fairly well in practise,
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
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.
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 ...................
