Environmental Specifications

Logging with PC attached included on all ECU’s. If logging without the PC connected is required, you must purchase one of the external loggers. This module simply connects through the CAN bus and is configurable, however it is preconfigured by Pro EFI for common channels to be logged.

1. The amount of available channels is dependent upon the use of pre configured I/O such as Fuel pump, TPS, etc…
2. Fault coding is a strategy used by the O.E. manufacturers. This strategy allows for the capability to trigger faults and fault actions. Features include but are not limited to multiple safety strategies for limiting boost and shutting off nitrous control under lean conditions. See your Authorized Professional EFI Dealer for more information.
3. Multiple Strategies are configurable based upon time or speed. See your Authorized Professional EFI Systems Dealer for more information.
4. V.E. stands for volumetric efficiency. This is a strategy incorporated by the O.E. manufacturers to more accurately determine the fueling requirements of the engine. There are several advantages to using this method. See your Authorized Professional EFI Systems Dealer for more information.
5. These communication ports are dedicated for the use of future external peripherals to be announced by Professional EFI Systems at a later date.

Adaptive – Is a term meaning that particular feature will self tune itself constantly. This is another strategy used by the O.E. manufacturers to help keep the vehicle in a constant state of tune for hundreds of thousands of miles.
