OEM CAN protocol for the Ford Focus RS/ST/ST225225 and RS500 models, used in combination with our MaxxECU Race Ford Focus plugin.
Please select the proper OEM CAN protocol in the drop down list, Configuration --> CAN settings, OEM CAN Protocols.
•All four wheel speeds from ABS
•Check engine light
•Turbo boost (0-1.8bar boost)
•Oil pressure gauge
•Low oil level light <-- hardcoded to DIN4 input (used by the plugin).
•Shiftlight indication on some ST225 models, uses the current revlimiter value - 500rpm to trigger the light.
•ODBII diagnostics not available with MaxxECU connected, use stock ECU during diagnostics.

Green (light): Working.
Green (dark): Working (but not controlled by CAN).
Blue: Not ECU controlled.
Orange: Partly controlled by MaxxECU.
Yellow: Turned off.
•The "oil pressure" signal in dashboard to the right is a "simulated" oil pressure signal (from RPM and oil temperature).
•Check engine light is connected to MaxxECU error diagnostics.

When we calibrate the wheel speeds from an OEM vehicle (to make an OEM CAN Protocol), we always use the stock wheel sizes, so to get correct wheel speeds within MaxxECU, you must calibrate your wheel dimensions, since they are used to show you the correct speed in MaxxECU.
