Does it now run OK on petrol without fault codes appearing?
At idle, on petrol, fully warmed up, what does the LPG ECU say? RPM being reported correctly? Lambda sensor signals both cycling between around 0.2 and 0.8 volts? Injector durations roughly the same and, at a guess about 3ms for each cylinder? Battery voltage plausible? Manifold pressure around 0.3 bar? Temperatures (vapouriser and LPG) reading OK?
Just remembered we had to change the injector configuration to 1 ohm injectors on James' install. Have a look on the side of the coil of your gas injectors and see if they are 1 ohm jobs. System defaulted to 3 ohm.
We had a strange issue with the controller software during one of our calibration attemps. It appeared to lock up and left the engine running with an odd combination of a couple of cylinders on petrol and a couple on lpg. Restarted the software, restarted the car and tried again and it was fine.
Might be worth switching to LPG and setting all the cylinders back to petrol using the little switch icons on the lower right hand side of the screen. Then switch one pot at a time to LPG and see if any or all cause running issues.
.. and I'll send that configuration file to you in a minute
