For any who have used Forscan (a free Ford/Lincoln/Mercury Windows programming tool), I’m sure you’ll agree. I’ve used it to diagnose actual problems like a bad O2 sensor with live data, etc. But the most fun I have with it is enabling features that are hidden from the factory, or features that are implied given the capabilities of the vehicle. For example, I activated daytime running lamps on our 2011 Fusion. Lately, I’ve been using Forscan to tinker with the DRL and other exterior lighting characteristics of a new-to-us 2016 Explorer 2.3 EB AWD. I’ve enabled the rear parking/running lights to come on whenever the DRL’s come on (always trying to be more visible on the road). I’ve also enabled a cornering light mode for the fog lamps. True, they’re not aimed like a dedicated cornering lamp would be, but as someone who never runs fog lamps for “foggy” conditions since most of them are pretty useless for that purpose anyway, putting them to somewhat of a good use is just cool. Now anytime I activate a turn signal, or move the wheel roughly 10 degrees from center, the corresponding fog lamp will turn on, and extinguish when the wheel returns to center. You can tinker with so much more, too. Many options like this are vehicle-dependent, and even trim level dependent, even being dictated sometimes by which gauge cluster you have. But it’s amazing to see the customization that is built in from the factory, but hidden to the consumer.
