One way to avoid inadvertant engine braking is to note what GPM (Scangauge) or injector pulsewidth (SuperMID) your warm engine requires to maintain your typical cruising rpm (1 GPM at 2000rpm for my F150) and then to avoid dropping into that GPM/pulsewidth range when driving, because whenever you do, your engine has switched over from propelling your vehicle to braking your vehicle. If you find yourself dropping into that range a lot while driving on a particular stretch of road, then its time for a coast or FAS.
