Looking for some help guys. I'm using an SCT X3 (PN# 3000AU) on an FG XR50T 2010 with LiveLink 6.4 I'm trying to manipulate some of the data logging I've done to see what PSI I'm running at various points. From what I'm told one way to calculate it is. 1. Convert map_volts to PSI by "map_volts - (2.45 / .17)" 2. Convert baro_press_cal to PSI "baro_press_cal * .14504" 3. Then calculate mapPSI subtract baroPSI I keep coming up with weird and negative numbers so there must be something I am doing wrong - either the calculation is wrong, or I am using the wrong source values. Appreciate any advice you have.
