How to calculate overboost on map 3

[StingerScott]

When looking for over boost in a log, am I adding the ecu psi(say 13), and target(6.0) and then aligning it with the actual boost I had like in the log I attached? Or am I way off, is this log ok in that sense? Thnx

here is what I found if anyone new to this is wondering how to calculate overboost,

1. Look at “ECU_PSI” (real boost) in your log.

2. Find “DME_BT” (target boost) for the same RPM.

3. If ECU_PSI is more than 2 psi above DME_BT, it’s overboost.


Example: If DME_BT is 17 psi and ECU_PSI is 20 psi, that’s 3 psi over—overboost.

Very handy thanks for sharing.

I was looking at my recent log with the wastegate adaptations to near 50 and it looks like its about 1-1.2 psi difference at most and it gets real close as revs go higher.

Gets closer when i bring the adaptations to about 45 or even 48. Was curious to see how the car was after the bms chargepipes were installed with the bms intercooler. Car definitely liked it!
