The EAS override is worth it alone for me. I run in the desert and there are plenty of places it flattens out into hard pack only for it to go back to rolling dunes minutes later. Rinse and repeat. The stupid auto lower feature over 50kmh would drop my stock lifted height all the damn time. This would make me need to re-raise for every approaching dune and thereby overworking the hell out of the compressor.
With the IID Tool, I have a preset of ~45mm lift at "Normal" height and I never have to screw with it while off road. As soon as I finish my trip, break out the IID Tool and set it back to stock settings. Plugging the module in and swapping presets takes under a minute.
It's also great for disabling TMPS for those using aftermarket wheels / tires. No need to blow hundreds of dollars on new TMPS sensors for new wheels. They are useless with big tires anyway. If you can't tell you have a flat, I don't know *** to tell you. The only reason most vehicles have them these days is because it is law for all manufacturers (selling in the US) to install them standard.
