Hey

Does anyone know how to do this on a single point landirenzo lpg system that takes feedback from o2 sensors.

The engine is adapting to the lpg so that when it runs on petrol it stalls, i had an adaptive reset done, drove on petrol and it was fine, once i started running on lpg again after a while it now just stalls on petrol.

Thanks

After the adaptive values are reset you need to drive it solely on petrol for at least 300 miles - This should allow your rig to learn 'good' Long trim values.

After this point the LPG 'short term trims should not effect it too much.

That is unless you have any other underlying issues.

To add to Kamran's suggestion I would say once the adaptive values have been reset and you have driven on petrol to establish a decent long term value you should have the lpg calibration checked. This should be set so that the short term trim values are as close as possible to the petrol ones for any given engine speed/load, if not you'll just end up with the same problems.
I am assuming that yours is a GEMS motor as if it is a Bosch you will never get a good result with single point lpg.
