Hi i have another custumer with a 6.1 supercharged + 450 walbro + 800 FID injector . The problem with this truck is when i use the cruise control on the highway above 80MPH or so the truck goes in Open Loop in m log , the AFR goes in the 12,8-13 an stay there is does not come out of the open loop until i hit the brake pedal. I realy don't know what is causing that.
Thank you for the help
