lpg first start up
« on: 11 May 2009, 18:53:24 »
i have only gone and finished the install, no really, only a year after buying the car and telling myself to put lpg on it asap. Ffs...(actually only took about 6days work once i had all the right bits and Kevin very kindly wired the ecu, not to mention a back up manifold from Lazydocker :-) )
 
Anyway, plugged the lap top in and ran the set up, got 2 errors from the software.
1, no signal from injector  no 4. Will look into that later as the plug is fully home.

2,injector nozel not big enough. More concerned with this one as the nozels are drilled out to 3mill as advised by Kevin and Moto gas. So, is this adjustment on the vapourisor, 10 mill allen key in the centre with plus and minus pressure on it?

Must admit it was a bit of a rush this morning so didnt really have time to play with it before i had to pack up for work. Any words from the wise before play tomorrow?

Also there is a brass screw/knob on the level valve on the tank, i presume this is to isolate the gas flow to the vapourisos and needs to be backed fully off? It has "36bar" written on it, or something like.

Cheers

Chris :-)

About time too!!!  :D :D :D :D :D

Anyways... Did you adjust the pressure on the vaporiser before fitting it? The large allen bolt you talked about, 10mm IIRCC, needs to be turned in approx 3 turns (I think) Basically you want around 2.5-3 bar LPG pressure showing on the software.

Are you getting any values at all showing? I hope you haven't got a dodgy connection under the plenum ::) ::)

Hmmm... That's odd. I would have expected you to get nozzles too big :-/ :-/ :-/ That's what I was getting, took 3 attempts to get it to auto calibrate. Could be that the pressure is too low if you didn't do as above

 have i got to read the instructions then. Missed the 2.5-3 bar bit. Hopefully thats causing to small nozel thing. And yes will probably have to take plenum off again for the injector issue.

What happened with the Injector 4 signal?

Now you just need to map it... May take a couple of goes though ::) ::)

Mine does have a hiccup as it changes from 1st to second at 5200RPM+ so I have set it to switch to petrol at this point... After all, it's rare it gets to that point ::) ::)

Dont know. Took plenum off checked all the plugs not just no.4. Found nothing. Well, found a breather pipe clip, eventually, right under the rather coolent bridge. Why do always get right down there? Re fitted. Plugged lap top in set the pressure to 1.23 bar, with a bit of fiddling as it warned up, and ran the calibration. Bingo. Job done.

First maiden lpg voyage? Curry house, its only right. :-)

Did give it a boot, no hick ups at all. Cant fault it so far. Will give it a proper work out tomorrow when the Mrs isnt screaming in my ear, but so far, do i need  to go any further with it?

Oh one thing, went to fill up and got a squeak at 35 litres ish, released the button immediately as i was unsure what it was? Do they squeak when full? Level sensor on dash had 4 lights but havent set that up yet so may well not be actually full.

Cheers. :-)

They squeak when it gets more difficult to pump - stop filling when it cuts the motor, you cannot overfill
