Yes it's not live change on the fly tuning. I had that with my power FC commander and this blows that out of the water. watched him tune 8-9 second GTRs yesterday with this and he's currently working on flex fuel for our cars... E85 anytime no switches or hooking up to a laptop. Just pump from almost empty and go. Changing back to 93 octane is the same. I'll be dealing with John from now on.
