I know this is the 6.7 section but my 2007 5.9 uses the same communication proticol as the 6.7. My problem is that I installed the Severe Duty Filtration Kit and went to the dealer to have the Star Scan tool enable the 20% bio diesel water in fuel kit option in the pcm misc. functions. The option was not there. I was with the tech and we tried to find the option but it was not listed anywhere in the Star Scan tool. Has any one out there installed the kit on their 2007.5 - 2009 6.7? If so, do you know the path used in the Star Scan tool to enable the kit WIF sensor?
