Engine Management in the Next Generation,The ProEFI

The ProEFI’s built in strategy to monitor fuel pressure for all types of fuel systems, allows for some really trick safety features. While monitoring fuel pressure, the PCM will see when the fuel pressure is not maintaining the proper pressure ratio across the injector. Although the computer will automatically adjust the injector opening time to maintain the proper air/fuel ratio, if a limit is exceeded, a fault condition will be triggered. The tuner can then setup in the fault management for Conditions 1 to default to base boost, Condition 2 to turn on the check engine light, Condition 3 to disengage nitrous, and condition 4 to enter a cut mode.rnRead more http://proefi.cebulink.com.
