Hi Guys,
I haven't had much chance to be around but wanted to make a comment on VE with respect to tuning. The VE you see in the fuel table in Megasquirt has little to no respect to the volumetric efficiency of an engine.
In Megasquirt the VE is a scale of 1 to 255. It is simply a number in a look up table the computer references to decide what to do next. It is not uncommon to see normally aspirated engines tuned with numbers over 200 in some of the Bins. We all know very well the engine isn't drawing in that much air on it's own. The VE number is scalable with a great respect to "Fuel Required" that is a rough calculation of injector size to an estimate of how much fuel the engine will want.

I have been through some Code issues with Megasquirt in the last month getting the Twin Trigger code working for motorcycles but I now have a nice running BMW K100 turbo conversion ready to go on the dyno.
