Hi there For the fuelling you would need to know the injector flow rates, if there are injector dead times set up and the algorithm used, I.e how many milliseconds the numer on the map equates to. So you'll see the fuel map numbers between the examples are quite different, but the ignition is similar... So as abase map to get you going you could use the ignition map if they are all degrees btdc , but you can't use the fuel map without understanding the algorithm used, the injector flow rates and other set up, e.g. Injector dead times etc. As above.....be careful....a lean engine under full load will destroy it self.... cheers Ian
