2013 Ford F-150 3.5L EcoBoost
Had high hopes for this unit; owned a CS unit previously in an Avalanche which worked great. I mainly purchased the CS2 for my F150 for the economy setting, and eventually the tire size recalibration. Day one on economy setting, and my MPG actually dropped from mid 17's to 13.5; back to stock configuration and the better MPG is back too. It also periodically doesn't power on until you press the "enter" key on the unit.
