This work with the analogue output of the zeitronix Ethanol content analyser?

In another word: Oui!
However our Evo friends from Finland are putting together a CANBUS ECA, which means less wiring.
The ECU input being used for the Analog ECA's to use is being borrowed from the Fuel Tank Pressure Sensor, on AUDM there is no such sensor, but there is on USDM.
So while USDM allows for easy connection (being that you just tap a wire and disconnect the real sensor), it has the added hassle of having to override the DTC. Whereas the AUDM car doesn't have a DTC to worry about but there is no wire to tap, so you will either have to find an ECU PIN (I have 50ish laying about if anyone wants one) OR use an alternate method for getting Ethanol Content into the ECU...
