Hi Guys,

I tried to tune my second LML last night and ran into nothing but issues with the truck. It had H&S on it previously and when I ran the VIN through TIS it said the OS should have been 12649244. I could not find this OS in any of the file repositories so I tried to flash in the 12649244OS and the truck would not run right. Has anyone had any experiance with this? Does H&S change the OS on the truck? I did a 2014 a few days before and everything lined up and worked perfectly. But for whatever reason this truck did not like the 12649244. I ended up just flashing a stock 12649244 into the truck and then reinstalled the H&S and he was on his way.

Could there be some sort of issue with H&S trucks something like the dodge setup? Does the H&S possibly flash other controllers on top of just the ECM?


Thanks

Mitch
