You and I came up with the same idea. I have found if it gets wet and touch screen fails to work you can stick it in a bag of rice and it will come back.I have mine on all the time. After your tune is dialed in, there are lots of other things to view. Like Smitty, I wish they were water proof. I carry a zip lock baggie with me.
Last summer we spent 10 days in BC and hit 3 days of rain, two days of serious downpour... PV worked before, during, and after just as if it were/is waterproof.
Hmmm, I didn't know. Now I'm gonna worry! NOT...
This is a flash Tuner so you don't have to keep it hooked up. I downloaded the map from S&S, emailed it to Dynojet for the Baker DD7 tweak, loaded into the PV, and installed map into my ecm.Definitely leaning this direction on the 124, S&S provides a map with my setup and I can email the map to S&S to have them "tweak" it for the Baker DD7 (so cruise & sixth gear indicator light will work). Currently running PCV & Autotune, the AutoTune will work with the PowerVision.
