Those who run LPG converted 2.2's

Cool glad it was something simple.

Feel kind of stupid now knowing it was such a simple thing, but the extra wiring from LPG system makes it hard to see things

All sorted now, might need a little adjustment here and there but this is as close as I could get it with multi and adjusting last point a little.

Done full boost test and vacuum hose buried deep within was leaking, same vacuum hose was connected to the reducer. Returned the points back to where they were and she runs again. Runs at 0.7something at the moment, but I'll adjust bring it down to get it down to 0.9, don't fancy melting **** down.

I think it's time to make some kind of vacuum connector manifold, too many T-pieces now.

A boost leak or the maf sensor. I had lots of maf issues which would cause a varying afr.

Something is definately not good with motronic as it runs 0.75 at points and can feel it loosing power, before it was about 0.8. What could cause rich running?

[hunker7]

I've noticed idle on petrol is slightly lean occasionally so I'll get a compressor off my mate and get it properly tested. Now that it's adjusted I must say it's running much nicer than it did before ir started to not work at all, so possibly it's been getting worse with time and I just didn't notice till it went completely bad. I don't look at aft gauge all the time.

On petrol she shifts it's just that point where it goes a bit too rich that bothers me. Otherwise boost is there and all.

I'm not sure. The Lpg system can take a while to bed in the injectors and such but if it's running odd on petrol too maybe there is another issue?

I'll get dad behind the wheel tomorrow night and go for a drive on M25. I've now adjusted the idle and that's stoichiometric now, I'll leave it as it is for now.

What could cause for it to go that badly? She was running fine before

Try a compromise multi as this will reduce the amount of tweaking the graph points need.

OK. I went a bit violent with the multi but it's definately helping. It is extremely rich at idle now and too rich at WOT as it starts shaking pretty badly. So I guess now I can just adjust each point separately to get it running right?

Last 3 points are now into 20ms last one being 29ms.

[diesel des]

Yep try that. It will make it more rich everplace.

OK, so I leave everything as is in increase that and see how it runs?

[diesel des]

Then you need to increase the multi. This is a basic scaler
