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 baroPSII 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.

Log BAP under 'environment'Log MAP under 'speed density'......IircPsi = (MAP-BAP)/2.036Same method as a dyno.Edit: off boost (vacuum) will be negative!

And if it's boost you want to read then you dont need kiwi wifi, you only need kiwi wifi if you want to read AFR's. But you also have to get an extra o2 bung put into your dump!Also if your andriod has video out you can use the ASL rgb box to then run the gauges from your phone to your ICC it's ultra cool to be able to flick from over to AUX on your ICC and have any gauge combo you want displayed!
