I didn't know there was a different setting, so I guess I don't know (I didn't ask if they had it on LPG setting). I'm going to talk to the installer this week - maybe he'll double check it for me.

Just for those that dont know,

Petrol and LPG have a different Air/Fuel Ratio for Lambda 1

ie Lambda of 1.000, is a Air/fuel Ratio of 14.70 on petrol, and 15.50 on LPG

This is also true for Methanol and Diesel..

see this page for the table http://www.techedge.com.au/vehicle/wbo2/wblambda.htm

Note the Methanol table ;)

Thanks for that. So does that mean if the dyno was calibrated for petrol and was showing a reading of 15, that it is more like 14.2 if the true correction was done? Is 14.2 acceptable? I though that it should still be around the 12 mark.
