Fuel pressure protection can save the engine should a fuel pump or pressure regulator fail while under load.


Its settings are fairly self explanatory, but be sure to correctly assign Fuel Press. RAW to a suitable Analog Input (where you have wired the 0-5v sensors signal), as well as calibrate the Fuel Press. HRT (under HRTs in the tree view) as required such that fuel pressure (under Inputs in the tree view) is read correctly by the ECU. More details on Analog sensors.


Pressures are in KPA - the below example is set-up to expect around 350 (3.5 bar absolute) of fuel pressure, and it will allow it to drop by up to 50Kpa (0.5bar) for no longer than 100mS - after that it will cut the engine by limiting it to ZERO RPM.
