When asking for technical help at the very least let us know the version of firmware you are running.Cliff's Calibration (Mapping) Guide is a MUST READ: http://www.vemssupport.com/forum/index.php/topic,97.0.html
Its not firmware related, but depending on your choice of Table kPa unit, if you've gone for a 400kpa sensor you'll have selected 2 (high boost) and you'll want the High Boost profile. We have this because high boost needs to scale its pressure readings differently to the lowboost.
