Deldran's VT adventure

[Steve @ VersaTune]

The ECU does not have a "Boost" logging PID. Boost is calculated by subtracting the ambient barometric pressure from manifold absolute pressure. We plan to add calculated logging parameters at some point.

On the other hand I think MAP tuning is more accurate than boost tuning. MAP will tell you exactly where the air density is while boost may not. Also, when looking at MAP instead of boost you can figure out the WGDC compensations so that you either get more air into the engine or slow down not to over spin the turbo.
