don17 Posted October 16, 2023 Report Share Posted October 16, 2023 as of a few days ago my link ecu can gauge isnt reading properly, the voltage seems like the most noticeable incorrect reading but not sure if the other readings are. voltage on G4 software says 11.7v but at the battery it says 12.6. I have a few CAN errors achknowledge error, bit recessive error, error passive, bus warning. this post above, is almost exactly what is happening with mine, i thought i had changed some fuel settings because it was running very rich error.pclr Quote Link to comment Share on other sites More sharing options...
Adamw Posted October 16, 2023 Report Share Posted October 16, 2023 Does the CAN gauge read differently from what is displayed in PC Link? Quote Link to comment Share on other sites More sharing options...

Adamw Posted October 17, 2023 Report Share Posted October 17, 2023 Ok, so it is not a gauge issue in that case. Is the voltage on the gauge and ecu changing when you rev it or turn headlights on etc or is it fixed at some static value? don17 1 Quote Link to comment Share on other sites More sharing options...
koracing Posted October 18, 2023 Report Share Posted October 18, 2023 What voltage do you measure at the ecu power pin versus the battery voltage? Having some voltage drop in the vehicle wiring is not uncommon. don17 1 Quote Link to comment Share on other sites More sharing options...
don17 Posted October 30, 2023 Author Report Share Posted October 30, 2023 Hi guys thanks for the replies, so I was only getting 11.6v at the main relay input and battery was reading 12.6v, looks like some wiring between the main relay output and a fuse had cracked solder and slightly melted. I cut and re wired, all fixed. Thanks for the replies Quote Link to comment Share on other sites More sharing options...
