At what temp are you switching to LPG. In TBE (KME Gold, Motogas shitty injectors), I have to raise it significantly to prevent stalling.

Sorry, busy as opps yesterday / just seen this 

Settings as follows ............

Switch over to gas - 25deg
Switchover threshold - 560 rpm
Switchover time - 30 sec

Max gas RPM 6700 rpm
Max engine load on gas - 100%
Pressure error time - 300 Ms

Gas calibration temp 95 deg
Pressure operational (bar)  1.04
Pressure minimum (bar)  0.62
Pressure error time 300 ms

Should the Vap not take its feed just before the HBV and then back in after the Heater Matrix. ie, in parallel with the HBV / Matrix

I cut the top pipe which goes from the thermostat - HBV and put the vaporiser inline so you get a constant flow.


I will proof read what I type one day 

If you suspect the Vap or a Tempreture issue, cheapest way to start is to give a good Flush and Reverse Flush the Vap as few times, whats the Coolant like and when was it changed last.

I had a Corsa Temp / Vap issue recently that was throwing all sorts of wonderfull problems at me, about 4 flushes later with Dish washer tablets and a drop of Fernox in the Cooling Sysytem soon sorted out over a few weeks, best do iut now before the Cold Weather licks in

Mmmmm 

I have been setting the heater to 20 deg at start up over the past few days but couldn't make up my mind if it was any better of not 

Last coolant change must be getting on for 3 years ago when the piggin oil cooler went 
Even though the heater matrix gets hot pretty quick, it can't do any harm to pull the pipes off the vaporiser and give it a flush.

Come to think of it, I did have a problem earlier on in the year with the gas pressure fluctuating but thought it may be the vaporiser which after all is 6 years old now.

Me thinks you might be onto something there 
I'll have a play over the next few days .................

Cheers lads 

Ive had quiet a few LPG Cars over the years now, all VX's ranging from 1.2 to 3.2, pretty much all of them have thrown a wobbly at some point or have come with the car when I acquired it, pretty much all the issues have been temperature related to do with the cooling system, or more to the point lack of heat or water flow, they all have thrown weird and wonderful faults ranging from Gas Pressure, Injector , solinold freezing, Miss fire, Ing issues or just switched back to Petrol or been slow to swtich on Gas.

Whilst Im no expert on LPG, water temp and flow would always be first call on any system that was working correctly, its a cheap fix should prove to sort the problem.

As it happens during warm up stage, I'd increase that temp one, maybe add 10C, and see what its like then

Much better running now the temp is set to 35 deg.

When I get chance, i'll remove the vaporiser and give it as flush to see what comes out 

What sort of pressure can these things take ?

Are we talking hosepipe or powerwasher ?

[Kevin Wood]

Hose pipe is probably the best plan although I'd probably fill it with a solution of washing / dishwasher powder first and let it soak for a few mins then flush with water.

If muck comes out, it's obviously an indication that the whole system could do with a flush.
