GM 3 BAR MAP Sensor
Use the 3 BAR MAP sensor with your Pro-M EFI system to monitor vacuum and/or boost. It can also be used as a reference to pull spark based on boost. Please note that the preferred method for providing the proper spark advance to your boosted engine is to simply let the Pro-M EFI PCM command an appropriate advance based on “Load". See your Pro-M EFI instruction manual for details.
