Walker motorsport Posted September 27, 2021 Report Share Posted September 27, 2021 Hi there, Im trying to run a Powertune dash on my G4+xtreme, i've purchased a CAN cable (Link 101-0019 ) and have set the ECU CAN settings to the settings as per the Powertune manual, but each time i plug in the CAN cable my PClink drops out / goes offline? Ive tried the 120 ohm resistor across the powertune dash with no change, even with cable only connected ( with each core disconnected ) the PClink drops off straight away. this is the first time ive plugged into the CAN port on the ecu and im not running any other CAN devices. what am i doing wrong guys? thanks for your comments. cheers.

Adamw Posted September 27, 2021 Report Share Posted September 27, 2021 It is the CAN dash cable that is causing the problem, this cable is only for our old DisplayLink dash that also used serial. It is having the serial wires connected that will upset PC comms. Is it a wire in ECU or plug-in? Quote Link to comment Share on other sites More sharing options...
Walker motorsport Posted September 27, 2021 Author Report Share Posted September 27, 2021 Hi Adam, its a wire in ECU. If the cable is causing the issue then how can i connect a CAN bus? i would assume the cable is only x cores connected to the socket? cheers Quote Link to comment Share on other sites More sharing options...
Adamw Posted September 27, 2021 Report Share Posted September 27, 2021 The easiest fix will be to open up the ecu case, and pull the yellow/grey/brown wires out of the little white JST connector inside that leads to the CAN port. They pull out quite easy - you just need to lift the small plastic barb with a sharp tool (or you can just snip those wires - unlikely to ever be used). Leaving only the Green & White connected.

Walker motorsport Posted September 28, 2021 Author Report Share Posted September 28, 2021 Hi Adam, i'm trying to locate a extra small torx driver to get the ECU open. If the cores on the lead/cable are individual, and only green and white are connected, then wouldn't that be the same as disconnecting the 3 cables at the JST connector? i cant see how that would make any difference? or i could strip the lead right back to the plug end and cut the extra cores. thanks for your help.

The long wires with no termination act like aerials picking up electromagnetic noise that kills the serial coms. Quote Link to comment Share on other sites More sharing options...
