I'm trying to figure out how to connect the ACD/AYC system to the Tunder ECU so that both systems remain functional.
I'd like to utilize a BOSCH DBW throttle body and an OEM Evo X Acc. peddle position sensor. This leads to a problem: ACD/AYC-ECU reads TPS-signal directly from the wiring (Pin 2 at the TPS to Pin 39 of Connecter C-37 ACD/AYC-ECU side). The TPS is supplied with +5V from the ECU and common sensor GND with: Coolant temp sens. and front O2 sensor. There is also another wire between Connecter C-51 Pin 79 ECU-side to Pin 36 of Connecter C-37 ACD/AYC-ECU. There is no specification what information is shared through it, but the OEM diagrams states the Signal is output from ACD/AYC-ECU and enters the ECU as an input signal.
Has anybody done such a conversion and can help out?
Thanks in advance.
My reply from a similar question on the Link forum below. The only thing you need is the 0-5V TP signal to pin 39. Pin 37 I'm pretty sure is just a diagnostics link, possibly K-line or similar.
