Shift on the fly

[sportsfreaked]

I am new to the world of diesels and tuning. I see a lot of post that say this tuner allows for shift on the fly. What exactly does shift on the fly mean and why is it of benefit? Thanks for your time.

Shift on the fly refers to the ability of the tuner to have multiple programs selectable while the truck is running. Edge, and Banks are examples of such programmers.
The benefit is you don't have to stop and reflash the truck to change tunes. Downside, most shift on the flys don't tune the transmission (on the 6.0 this is a fact, on the 6.4 you'll have to check into that still being the case).

the minimaxx is shift on the fly and does include transmission tuning.

That is correct, you can change the power level of the truck while it is running. Most tuners will require you to shut the truck off to change the power level. The H&S Tuners are shift on the fly and they tune the transmission.

Hey everyone thanks for sharing the knowledge. When I do tune which will not be anytime soon it sounds like shift on the fly would be the way to go.
