Evolution 8 G4+ PnP With E-Throttle - ACD/AYC ECU "without" TPS

Hi All

Seeking some guidance from those running a DBW set up in their cars.

In preparation of installing my E-Throttle setup, I'm trying to work out how to get things interfacing with each other, one of those items being the ACD/AYC system - particuarly the 4WD ECU.
As I understand it, the 4WD ECU requires a TP input - how does this work when the conventional TPS is removed in lieu of a DBW TB+Pedal set up?

Additionally, how do the EFI ECU and the 4WD ECU talk to each other?
Is it as simple as the 4WD ECU inputs being spliced in from 0-5V (ie. 0-5V from TPS being spliced somewhere and fed into both ECUs?) or do they communicate via a more sophisticated setup?

Thanks all!

Yeah, the only "comms" to the ACD ecu is just  a shared 0-5V signal from the TPS.  If you use the original TP wire to connect the new DBW TP main then it will just work with no other mods.  If you are going to run new wires to the TB, then you will need to splice TP main signal to pin 39 of the diff controller.

EVO9 G4X plug-in There is a problem with the ACD pump not working with the electronic throttle control. Splicing TPS plus to 39 didn't work. I have not tried connecting the stock throttle position sensor to 0-5V. I use a Bosch electronic throttle.
