Rear O2 Input Function (FlexFuel and more)

USING Custom Maps we can import two separate sensor signals through the rear O2 sensor wiring.

This unique feature offers many possibilities, among them...

You can set up fail-safes based on these voltage inputs or even display the sensor values on the centre display using the gauge hijack function. If the rear O2 sensor has been removed or the signal wire is re-purposed, the fuel trims long-term (AF Correction #3) can also be disabled from acting in Open Loop.

This additional input can be used for any number of options when you need a 0-5V input into Custom Maps.  Click here to see Cosworth in action on our dyno. They are using Pot B (via the rear O2 sensor input) to adjust the direct-injector firing angle while the vehicle is held on full load, and Pot A to adjust the ignition timing (via the CPC pressure sensor input).
