Installed PL with the 2.2 SM chip. :cool: Running PL v1.4.0 and re-flashed to PL030.
Car has electric FP and electric Boost gage.

Question 1 - Looking at the log, FP is accurate when the car does not run. Once the car starts, FP drops to 6 psi on PL, but the electric gauge stays at 38. Verified FP with a mechanical and autometer gage. . . . both match. :confused: PL analog block location is 5, setting is Pressure5, voltage is 0.650V.

Question 2 - Electric boost gage is 30 psi autometer. Seen it go to 22-23, so I know it works :biggrin:, and boost matches the setting on MSBC.
Boost gauge runs off a GM MAP sensor.
After reseting PL – “Crl+B”, "PL - "3 bar" boost reads -.06 inHG engine running.
On 2 bar, PL reads -13.6 inHG. (Voltage = 1.870V engine running, 1.531V engine off key on.)
SM reads about Bst -16, and the mechanical vacuum gage reads about 16 inHG. :confused:

What do you think? Screenshots attached.
