LPG Discussion Forum

Speaking to Dai last night I think I have a suitable way forward for this. Its going to be quite a simple system which is easily removed (well most of the electrics will be permenantly mounted), Installing/removing the gas system should be doable in a matter of minutes, with some jubilee clips and a ...

My dad had a system installed an New Farm about 5 years ago on a Saab and they were pretty good. Its also where he got the car serviced...

No problems with them

I have 2 different ECUs in my posession with 2 different plugs.

The one I am using has a black plastic socket, with ovalled ends. I can't remember if it has 3 or 4 pins in it (I think its 3). The socket is about 30mm x 12mm.

(The other one has a white 3 pin socket with much smaller pins and is ...

Hi Guys

Can anyone give me some advice? I am trying to connect to my BRC just system with my computer to set it up.

I have a cable similar to this http://www.ebay.co.uk/itm/PROFESSIONAL-LPG-INTERFACE-CABLE-LANDI-RENZO-ROMANO-RIS-/281065473521?pt=LH_DefaultDomain_3&hash=item4170cec5f1 but with the ...

I will put in a generic rev limiter to stop the over-revving.

I do like the oil pressure switch cut out idea. And a simple full throttle switch will be easy!

I also have spare engine which can go in it if I blow the existing lump up (its not the original one anyway, its from my other van - the one ...

I fill my diesel at least twice a week...

I work 270 miles from home...

I think its worth a play...

If I have time I might knock something up over the next week.

I would think MAPP is going too far though

I've had a silly thought today...

If I were to get a disposable propane cylinder (i.e proper 1" threaded plumbers one) and inverted it I could mount it upside down (so it forced liquid out) I could use this as the source of the LPG? It would mean I didn't have to cut any holes in the bodyshell and ...

I must admit that is more what I was thinking initially...

No, you'd reference the vap to manifold like you would in a petrol turbo

I have to say, that means nothing to me...

The injection pump of this particular engine stops injecting diesel at approx 4250 RPM, surely if there is no diesel then the LPG cannot ignite? But rev limiters are easy enough to ...

well an idle/throttle switch is easy to put in, at idle stop the solenoid.

Dai, so am I right in thinking running without an ECU, an on/off switch to switch it on above idle which controls the solenoid valve and control it via a power valve?

As its turbo'd there is at least 1 Bar pressure in the ...

Also... does an LPG filler have to be mounted on an external surface of a vehicle, or could I mount it in the door step??

I will just have to be careful then... Or kill an engine, which would be a feat given how bullet proof they are

Would a normal single point petrol system be the thing to use (open loop)?

I have a spare BRC Just front end system (will need a vapouriser and tank but have everything else)

bottom end will stand it! The engines are absolutely bulletproof - if they have oil in they are fine, coolant is optional :shock:

Even if its not, I will get it towed to nearby services/garage etc, ring the RAC for recovery and put one of my spare engines in...

Last time out was 19.5s & 70mph at ...

I've got an old 1996 2.5di transit which I am trying to get the most power out of. I have already turbo'd it, fitted the biggest available injectors etc and drag race it occasionally.

I have read that introducing LPG in to the air on a diesel will help the diesel burn and give an increase in power ...

Well it seems ok...

There is no appreciable power difference until the gas starts running out, but my diagnostic box says its always running lean with the stepper fully open

Time to try my manifold idea I think and to reprogram the system (which I still havent done yet)

I have blanked off 2 ports on the mixers, run a single power valve Y and its worse

Im leaving it like that at the moment though, because it seems to be okayish (I will find out next weekend) but I am going to manufacture my manifold and have it rigid piped as far as is practical.

Its not actually all that lumpy - but the stepper is right next to the vap. so moving it might help I just hope it has enough cable!

Thats what I was thinking, but I will try blocking 2 of the inlets off & compare stepper positions ;)

Once I know its working, I will be pulling it all apart again and putting it back together much neater and in accordance with the COP11 (which I didn't have/know about when I put it in the first ...

I suspect that too, but tinley tech advised against doing that, I may have space for 1 power valve and no Tee.

I will get a bit of 12mm, and shove something up the center to block it and join 2 of the pipes together (looks neater than a bolt shoved in a pipe :lol: ) and have a play.

Are plastic ...
