Hello I was wondering if there are any programmers for a 2004-2008 f150 5.4 that can be shift or changed on the fly without having to shut down and go through that long process. Thank you!

 

No sir. You must go through an upload/download process to change complete program.

 

X2

Would be nice though!

 

Thanks everyone!

 

I had asked a similar question a few weeks ago about using the OEM tow haul switch, it sounds like some custom things can be done:

The other open question I still have is that if you do the full flash to upload a new program (or swap between two) does the engine/transmission have to go through it's learning cycle each time?

 

Yes it does.

 

There is a new tune out with JDM tuning that is a all in one tune.. Perf/Tow/Economyall in one. They are pretty pricey. I contacted them and we may be working out a deal where i test the tune for them. If so i will post on here about the tune.
