ac on - aveo off on LPG

Hello everyone,
I have problem with Aveo 2007. 1.2. During drive on LPG with air condition on max-4 car sometimes turns off when i press clutch change gear. the RPM goes down it seams too much.
I don't have that problem during driving on petrol-benzine.

I noticed that time of injection (ms) of LPG and petrol is much higher when I turn on AC.
I can change map of LPG by increase time of injection on diagram, but still have the same problem ( I'm still playing).
I even start auto calibration with AC on, but still got same results.


On map i have LPG and petrol-benzine curve almost the same.

My question is did anyone had similar problem, and any idea for solve it.

Thanks a lot.

What RPM does the car idle at with the A/C on with gas, and what does it idle at with LPG? You might need to increase the idle RPM with LPG.
