Superchips claims to be working on it, but seems like it's been over 2 weeks and no fix yet. CLEJeepGirl. 04-23-2013, 10:38 AM. You're right I called them, they said you can't, guess I'll have to get the Procal, you can do shift points with that one. I don't see that listed on the ProCal site.They basically do exactly the same thing except the ProCal is all dipswitches and the FlashCal is through a video screen.Where does it say that the ProCal will let you change shift points? I'm curious. What I've been told is that by entering your tire size and gears that it does make adjustments...on both brands.ost people I've talked to use them once to make settings and never use them again. Rox that doesn't work. Once you use the tuner it is locked in to your VIN number and can't be used on another vehicle until the tuned vehicle is returned to stock.
