I posted in the FI section but didn't get any info. Has anyone had any luck correcting the issue on this code? My cars a 2015 with a Fore Triple pump, the battery is relocated to the back and the fuel pump is connected to the battery directly. Its activated through the brake pedal. Im wondering if my new tune could cause this CEL ? I read that it causes the fuel pump to perform at 80% duty? Any suggestions would be great, I've checked all the wiring, etc... and I didn't have this code prior to

My new tune

Thank you. I reached out to Fore today and they said depending on which way the pumps were wired that the tuner will need to fix the issue. I read that thread yesterday and again... thanks

PBD sent me a different file and told me to try it. It worked and shut off the light. It was definitely in the tune.
