mig23t Posted August 18, 2023 Report Share Posted August 18, 2023 Hey brains-trust, I cant remember if i saw it on this forum or not. Is anyone familiar with the extra steps involved with setting up a DBW set up on the evo platform? Pedal and throttle on mine is working superbly, however the car throws the 3 ACD lights up on the dash immediately as the car starts moving - when first started it will show whatever mode is selected (tarmac, gravel,snow) then holds all 3 on as soon as its moved. From memory there is something that needs to wire to the ACD ECU, but cant remember. Is anyone able to shed some light? G4+ pnp ecu.

Adamw Posted August 18, 2023 Report Share Posted August 18, 2023 The ACD ecu needs a TPS signal to pin 39, typically you dont need to do anything if you use the original TPS wire to the throttle body. Quote Link to comment Share on other sites More sharing options...
mig23t Posted August 18, 2023 Author Report Share Posted August 18, 2023 Thanks Adam, I created my own wiring loom and didn’t include that. I’ll sort it out Quote Link to comment Share on other sites More sharing options...
mig23t Posted August 26, 2023 Author Report Share Posted August 26, 2023 Hey @Adamw Just on this, Ive spliced my tps main to what i think is the correct wire/pin on an evo 7 ACD ecu (solid green). Ive just bridged the two with a splice and am experiencing an erratic idle with ECU Fault Code 29: An Volt 7 below Error Low value. To get rid of this, should i Have cut the solid green wire at the ACD ecu end and just crimped in my spliced wired from the TPS main? In my head i think Ive created a loop which is giving the feedback to the Link ecu and giving the error? Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 26, 2023 Report Share Posted August 26, 2023 If you dont know what the other end of the wire is connected to, then use it would be best to cut it. Quote Link to comment Share on other sites More sharing options...
mig23t Posted August 30, 2023 Author Report Share Posted August 30, 2023 @Adamw thanks. Ended up cutting the remainder of pin 39 wire and terminated it safely but still experiencing the same 3 lights on the dash issue. Something more sinister at play going on. Or should I be looking at depinning the factory tps wiring from the ecu connectors and removing that from the equation all together? Currently the factory tps connector in the engine bay is cable tied to the firewall in free space Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 30, 2023 Report Share Posted August 30, 2023 So if im following you correctly, you now have a new wire running direct from the TPS to pin 39 on the diff ecu? What voltages do you have at pin 39 with the throttle open and closed? Quote Link to comment Share on other sites More sharing options...

I’ve got the system working now with the 3 diff modes back and functioning Cheers. Quote Link to comment Share on other sites More sharing options...
