    "double stoich, halve IFR" scale question

    I'm working on an 08 Z06 with a Vortech. I scaled the tune using the "double stoich, halve IFR" method. Now my commanded AFR is double what it should be. What do I need to do to get the commanded to read correctly?

    It won't read correct unless you scale the long way.


    Use lambda and your life will be easier.
