ProEFI – The Next Generation in Engine Management

　　ProEFI’s goals are focused on making the engine control highly consistent, adding a high degree of safety to protect the engine, and give the driver simple feedback that allows seemingly simple changes at the line to consistently, and safely get the car down the track. At ProEFI we are constantly developing cutting edge strategies, and technology to save the consumer money down the road by protecting anything the powertrain module controls!

　　FAULT MANAGEMENT

　　Fault Managementis a strategy used by the O.E.M. vehicle manufacturers for years to help protect the vehicles powertrain. The tuner has access to numerous conditions the Powertrain controller is always monitoring. This allows the tuner to setup minimum and maximum operating conditions of the powertrain. If any of these conditions are exceeded or have not been met, then a fault is triggered by the PCM. With this fault trigger the tuner can setup a set of actions based upon these triggers. These triggers all have adjustable sample rates to allow the tuner to fine tune what is truly a fault condition or a quick blip in a transition state. When a fault is triggered, a code will be set that can be read from the blinking of a check engine light, or from a laptop connection. ProEFI’s base fault codes are based upon OBDII protocol for faults. These codes are tuner selectable and may be changed by the tuner as well.

　　Example 1: Lean condition – The tuner has set a lean fuel fault condition to trigger a fault at above 12.5 to 1 Air/Fuel ratio when manifold pressure is above 150kpa (7.3psi). The tuner can now go in to the fault management and set condition 1 to trigger a check engine light, condition 2 to set the boost to minimum allowed boost, condition 3 to disengage nitrous control, and condition 4 to enter a cut mode, either ignition or fuel. The tuner can now set this fault can either be released when normal operating conditions are met, held until the ignition key is cycled, or held until the fault condition is reset by the tuner.
