Simon, fair enough, perhaps i will just start with that one then and go from there if you reckon its a good safe option, its certainly easier than starting with a blank screen and working out guesses based on flow rates etc.

Fuelling i can sort in no time at all anyway, so its just the ignition i will need to spend a bit of time on, but thats not the end of the world.

If you have a couple of other maps you could send me though along with details of the spec they are for, it would be good for educational purposes as it all builds my familiarity with a new engine that im not used to!
