Calcuated MAP vs Measured MAP

Since Ford vehicles are not equipped with a MAP sensor, besides having a dynoameter and attempting to tune on the road how would we find our calculated MAP to measured MAP to calculate the error?

It's a bit of a pain unfortunately but you could add a MAP sensor to the engine and then bring this into the MPVI2 interface using the Pro Link module. This way you can set the MAP sensor up as an analogue input and log it alongside calculated MAP. This would make life much easier since you could then generate a math channel giving you the error.
