Can I switch programmers on my 6.4?

[whodeymeadows]

Hey,I have an '08 powerstroke with dpf/cat delete,egr delete,afe intake and have been running the sct livewire..I was wondering if it would hurt anything if I upgraded to the mini maxx?? Also once I have a tune loaded do I have to keep the programmer plugged in or can I remove it? And if so what if for some reason the battery is disconnected? Will it still keep my current tune loaded?

that batt disconnect won't affect the tune

but you need to return to stock when going from the SCT to Maxx

as far as the live wire and mini being plugged in all the time that I don't know for sure ,, i use one you load and unplug

As long as you return the truck to stock with the live wire then you can load the mini maxx onto the vehicle.

No you don't have to leave it plugged in but just out of curiosity why wouldn't you leave it plugged in for guages and the adjust on the fly option?

If you dont want to leave it plugged in why not just go with th XRT pro and save some money too. JMO

Don't forget to unplug the sensors if you get the mini maxx.the mini maxx doesn't need the sensors in the exhaust like the sct does and if u leave them p,urged in it could have issues with the h&s. both you can unplug and the tune will be left on what it was on when u unplugged it

Damn what issues can it cause because this is how I have mine after switching from SCT to H&S

Hopefully someone can chime in with the correct answer but I thought it messed with the tuning but maybe I'm wrong if your truck is running fine

I think its running fine. After this last update from h&s its been crappy. In park, neutral, or driving its have fuel rail pressure spikes between 1900-1950 rpm and makes the rpms go up and down. Makes for unpleasant city driving as that's exactly when my gears shift. Lol

Ha I just checked their website for updates and sure enough they already have an update for the problem. Gotta love h&s

have a similar issue with my KEM 345 tune on my livewire.. right around 1800 rpms.. slight throttle, the rpms go up and down.. and its right where my tranny likes to shift too.. makes for hassle.. but i love the rest of the 345.. just need send KEM a data log so he can fix it
