Santatu Posted April 3, 2021 Report Share Posted April 3, 2021 Good morning. My ecu Xtreme X was working perfectly. He loaded the map and everything is perfect, the signal works smoothly with the display, everything is perfect. I have started it again but the fuel pump does not stop always connected and the PC does not connect to the ECU. What is possible that is happening?

Adamw Posted April 3, 2021 Report Share Posted April 3, 2021 Your symptoms suggest the ecu is not powered up. I would start by unplugging the ecu and confirm you have 12V on pin A5. Quote Link to comment Share on other sites More sharing options...
Santatu Posted April 4, 2021 Author Report Share Posted April 4, 2021 Hello everyone and thanks for the answers. I have already solved. If it had 12v on pin 5. The car started perfectly and everything worked, the only problem was the fuel pump always connected and it did not connect me to the PC. I had to update the ECU to get it connected again, and it was not easy to do so as it did not connect to the PC. Quote Link to comment Share on other sites More sharing options...
