At present, there is no "ON BOARD" electronics for wideband sensors only
narrow band types as this would add extra expense to the ECU that not everyone
would need.
This means you need an interface to convert the wideband sensor data to a format
suitable for the ECU. I will be doing a black box interface to enable a wide band
to be directly connected to the ECU at a later date.

The ECU can read existing widebands meter such as Motec PLM etc either using a
linear voltage interface and/or serial data protocol depending on type.
