Monitoring Boost
More LNF histograms, a config file for monitoring boost and a custom PID.
The following custom PID is required for the attached histograms with 'Cst PID' in the title. The other histograms use the factory boost sensor PID.
This PID uses MAP sensor pressure as the engine pressure reference and subtracts atmospheric pressure.
Code:
Convert MAP to Boost Pressure -
Formula: (MAP Sensor - BARO) / 6.894757
Name: Boost
Abbrv: Bst
Sensor: none selected
Units: psi
Function: ([SENS.30.MET] - [PID.2340.MET]) / 6.894757
This PID uses the factory boost sensor as the engine pressure reference and subtracts atmospheric pressure.
Code:
Boost Pressure (psig) -
Formula: (Boost Sensor - BARO) / 6.894757
Name: Boost
Abbrv: Bst
Sensor: none selected
Units: psi
Function: ([PID.2336.MET] - [PID.2340.MET]) / 6.894757
NOTE: Do not open the .cfg or .hst files with anything but the scanner.
For version 2.22 and later, file locations are as follows:
The .cfg (configuration files) go in your:
C:\Documents and Settings\<USER NAME>\My Documents\HP Tuners\VCM Scanner\Configs
The .hst (histogram files) go in your:
C:\Documents and Settings\<USER NAME>\My Documents\HP Tuners\VCM Scanner\Histograms
