  • ECU includes an onboard 7-bar MAP sensor. 
  • Most factory features are supported. 
  • Check the features tab for I/O expansion options 

Note: This Plug-in features a new 4-pin powered CAN connector and cannot use the old CANPCB cable for CAN connection.  Use the CANJST4 (Code 101-0198) cable for connecting CAN devices.  This new 4-pin port and cable provide not only the CAN connection but also a protected 12V power supply and ground for powering the CAN devices.  The power supply is protected by a self-resetting fuse rated at 3A continuous.
