That's a fair bit different to mine. I have no idea what the top line is but am thinking the second line down is air pressure or vacuum.
I can't really see why there are so mine lines on there, as the last eleven are all the same, and quite a few of the columns are as well.?
All I can suggest is to read up on what LPG and a higher compression ratio requires of your spark map, and apply that to it, then take it for a run and see how it feels. Does the blackbox have any way of logging?
When I put mine together, I just followed Des Hamills book on the Rover V8 to get the base line, then added the vacuum amounts to fill the map. This made up my base map, then I did the fuel map with the help of logging and an afr gauge, and the feel of the car.
Where did you get the map you currently use?
