I am unable to read my LLY at high speed no matter what fuses I pull. Both batteries are fully charged, my laptop is fully charged, the winds blowing the right way, it's not a full moon, yada, yada, yada. I can however read it in slow speed, but I cannot read the ECM & TCM in the same read. I can read the TCM separately however. All good right? Not quite, My ECM reads that i have 3.73 gearing while me TCM shows 4.10. Is this normal? Has anyone else seen this? Is my read corrupt? I'm attaching my reads in hope of some assistance. New to diesel but have plenty of experience with gas motors. Thanks in advance.
