Boost value from datalogging not accurate

Hi, im facing problem with boost value not accurate from datalogging…mostly stay at 0 value,any idea?

Do you mean that Boost value is written to datalog file incorrectly, or is it just displayed incorrectly during playback? Could you send me your datalog file and describe how to test the problem?

The datalog file too big to be attached here, will make another shorter datalog…but here is the video how it shows while playback.

Here’s the datalog file

I will take a look. What inputs are your boost gauges attached to?

Tried both Boost(bar/psi) & Boost(psi),same result…
