Logging of boost pressure no MAP values

Just wondering if anyone can help. The overlay boost gauge works fine with my car and displays as it should so the app is getting data from somewhere. When exporting a csv file there is no column for boost pressure and all map sensor values are 0. Any ideas? Car is a 2008 Focus ST 2.5T.

Hi,

Your car does not support the MAP PID-which is the reason you don't get it exported. In case LapTimer detects a car is supercharged, it either uses MAP as delivered by the car, or it calculates it from MAF, intake air temperature, displacement and volumetric efficiency. I'm not sure how precise this value is, but it gives you a qualitative value at least. Calculated MAP is not made available for exports currently.

Thanks Harry. I don't seem to be able to get a boost reading from this car on any sort of OBD reader, doing my head in :cry:
