Kaui's video: Hypertech Max Energy 2 0 Tuner AFM Disabler - 2015 Chevy Silverado

*Video is long, sorry. Training for your patience, you'll need it. Wanted to get as many menu/process bits.* My thoughts on the Hypertech Max Energy 2.0 handheld tuner. The engine tunes and various transmission tweaks are going to be up to the vehicle and preference of the driver, but I've basically turned off all "tune" features. I'm using it right now as a glorified AFM disabler, but thats what I bought it for anyway. From what I can tell, this is the only handheld that you can turn the AFM off below a certain speed (I have mine off less than 30 mph). A much smoother driving experience. Keep in mind, this is a used/new eBay special (~$200) and thats probably the reason I couldnt update the thing via USB PC connection. Edit 10/2/19 - Was able to update it with the newer hypertech software. Have not tried the performance tunes, but now my settings are: AFM off below 15mph - yea, I know, my average speed is less than 20 : ( Shift response - Street Raised top speed and everything else stock Set my vitesse controller to eco mode 1 (what!?!?) but it works best with my driving and the more aggressive "street" shift response (downshifts faster). Pretty happy!
