Those who run LPG converted 2.2's

Yep it's kinda cool. Good luck should be fine.

It shows that pressure is too low or tank is empty?

[hunker7]

As soon as it reaches 25C there is a click from the tank and it says about pressure being too low. Do I need more lpg in the tank?

[diesel des]

Check that has is leaving the tank by cracking the pipe fitting up near the vapourisor. If no gas check the manual valve is open if you have one. Then check after the vapourisor near the injector rail to see if gas is present. Is solenoid on vapourisor getting power. Could be wireing to solonides if no gas or pressure sensor if gas is there.

There is gas at the vaporizer, and solenoid seems to be wired up too. There is a blue-black wire and blue-red wire on the redicer solenoid where do I connect blue-red wire? I have it as ground currently

UPDATE: It now switches to gas, but it starts stalling and juddering. Looking at the readings tab, it looks like it doesn't switch petrol injectors off? I get readings for both injectors.

It will turn the petrol injectors off once it transions to gas. It does one cylinder at a time. You now need to start the calibration process. Autocal is now a good starting point. What readings have you for gas pressure when it tries to run on gas. Have a look at lambda when you switch over. See if it goes rich or lean and also look at petrol ecu durations to see if motronic is adding or taking fuel. Once calibrated motronic pulse time will not change when swiching to gas as the gas flow will equal the petrol flow.

Take a pic of the calibration map. What nozzles are in the magic jets.

Pressure is about 0.9 bar.

So it's ok that it runs pretty rough at the start? It also shows load, and load on petrol injectors increased as soon as i switched to gas.

Should I start calibration process when it's fully running on LPG?

Magicjet came with screw in nozzles that I left in, should I take them out?

[diesel des]

Yes if it's increasing the injection times than it's likely to be lean. Remove the restrictions and try again. I think you start the calibration process with it on petrol. Follow the on screen instructions. Do it with lights and all electrical loads off. Then it asks to increase load. Turn all lights on air con on full and put steering at full lock etc. This is from memory. Its so the ecu sees 2 different operating points to scale itself against.

Thanks. I'll take out the injector inserts and get car upto temperature (reducer needs to be 50C to start AutoCal), I assume I have to override the auto switch over at 25C?

[diesel des]

If you use the button in the car to keep the gas off Then start the Autocal. That should do it.

OK thanks mate, I shall try it tomorrow and hopefully it will go as planned

If I remove cables etc later I don't have to calibrate it again?

[diesel des]

That's correct it remembers. But back it up to your laptop just in case.

Will do. Thanks, I'll report back tomorrow

[diesel des]

Cool. Once you get your head round what's happening it's actually quite simple. Just stick with it.

It's probably because I don't know what to expect, so when car starts juddering and stalling you don't know what to do
