I have a friend that recently put a supercharger on his d series. I did all the procedures on crome for boost etc etc, car datalogs fine, but its not showing boost on the datalogs and crome is not going into the boost cells. Could the map sensor not be reading boost at all?

 

No, if the cells are all grey out, you have to close it and reopen. I hope you add the boost cells to the map.
