So is there a benefit to those of us with WMI, or is it 6 in one hand, half a dozen in the other?
It doesn't apply to those running WMI, unless you're also running E85, and have a need to know your precise ethanol mixture.
When running E85 exclusively then the sensor feeding mixture data in to the JB4 becomes much more useful so boost target is preset based on your actual E85 mixture.
