NikoP Posted November 20, 2023 Report Share Posted November 20, 2023 Main relay is always on even when ignition switch is on or not. Ecu is grounding the main relay. Tried it with the old ecu and it was working normally so the issue is with the new ecu. Here is wiring diagrams. Problem is with ecu pin C23 ecu wiring.pdf ecu wiring 2.pdf Quote Link to comment Share on other sites More sharing options...
Vaughan Posted November 20, 2023 Report Share Posted November 20, 2023 What Voltage is An Volt 12? (Connected to B19 but you can read the voltage in the software) Quote Link to comment Share on other sites More sharing options...
Adamw Posted November 20, 2023 Report Share Posted November 20, 2023 Can you also please attach a copy of your tune, preferably save it when the ign sw is off but ecu is still powered up. Quote Link to comment Share on other sites More sharing options...
NikoP Posted November 21, 2023 Author Report Share Posted November 21, 2023 An Volt 12 is 5,00V when on and 0,00V when off So do i put ANV 12 Active State to low from digital inputs -> ignition switch to read ecu when car ignition is off to send you a tune with ign sw off. Sorry im pretty new with this stuff. Quote Link to comment Share on other sites More sharing options...
koracing Posted November 21, 2023 Report Share Posted November 21, 2023 No just save the tune with the ignition switch off and then upload it here, or share via a dropbox, google drive, onedrive, etc. shareable link. Quote Link to comment Share on other sites More sharing options...
NikoP Posted November 24, 2023 Author Report Share Posted November 24, 2023 Attached map with Ignition switched ON and OFF. Any ideas what might be wrong? With original ECU there is no problem like this. ignOFF.pclx ignON.pclx Quote Link to comment Share on other sites More sharing options...
Adamw Posted November 25, 2023 Report Share Posted November 25, 2023 Ok, it looks like the ign sw input and the relay control logic in the ecu is setup correctly and working as expected. Can you check voltage on pin C23 with the ign sw off - I would like this measured by "back probing" with a needle or similar so everything is still plugged in as it normally would be. The most likely explanation I can come up with based on your symptoms initially is possibly the FET that controls pin C23 is damaged/faulty. This voltage test will confirm that.

NikoP Posted November 27, 2023 Author Report Share Posted November 27, 2023 I measured the voltage on pin C23. It was 6.58v with ign sw off. Quote Link to comment Share on other sites More sharing options...
Adamw Posted November 28, 2023 Report Share Posted November 28, 2023 Thats odd. The only logic I could apply to explain that would be something faulty on board. I think you will have to contact [email protected] to get it inspected. Quote Link to comment Share on other sites More sharing options...
