    cab/chassis tuning

    I tried to read a 2012 2500 Duramax and it took less than a second to say it read it. Then I tried to read a 2011 Cab and Chassis Duramax and it would not read. So my question is what is the difference in these two ECM tuning? Thank You for ya'll help

    2012 is a lml which doesn't get read out of the ecm. A stock file is provided by hp. The OS in 2011 might not be supported but you would have to contact support for that. They might be able to help you out.
