Anyone know what scale Fiat uses for boost? On my logs the boost at idle is 29.6 inHG, which doesn't make a lot of a sense since that is 14 psi - in Torque I can see that it's actually -22.5inHG, which makes way more sense.

Your logs are showing absolute manifold pressure. You can log both but the app is just sliding the scale up 14PSI to reference that as 0 boost, and showing the lower as vacuum. This also presents another problem in that the OBD port only uses an 8 bit register for all data so the max value for anything is FF or 256 steps. For boost this caps the max reading at ~22.4PSI even if you have an analog gauge tapped into the boost line that shows more actual boost in the tune.

I was hoping if you can recommend a fast polling logging tool and software, I’m using OBD Fusion which has fast polling feature but I do need a OBD2 scanner that is up to par that has a fast polling feature. I am currently using kiwi 2
The data refresh rate is too low, it’s like 1.1-1.5s every data pull. I normally have to do multiple runs for some accurate data.
