I got the "additional tuning required" message and just let it do its thing. I had issues too and founds some answer here on the messageboards. One issue I had was after I finally got my stock tune backed up, I was installing the 91 octane and my screen went blank, white screen of death. I read ...

Tuner refuses to recognize my car. Phone tech told me to mail it in to be checked out. He never seen the "additional tuning required" msg either.
I cant find my receipt, I sure hope you guys will honor the warranty with a copy of the dated packing slip. Oh well, rather its the tuner then my pcm ...

The tuner has always said it was up to date. I plugged it in the car and got the same issue.
Tuner boots up, I pick the "Tune Vehicle" icon, "yes" to the agreement, click the "write tune" icon, then it tells me to put the car in the "on" position without starting it. Then it goes to the black ...

Here ya go Garret.

things get misunderstood in text I guess, thanks for spelling it out for me. My tuner is acting funky now, I'm done with it til I call support.

well apparently since I stopped it after it wanted to do additional programming last night, now my DCX wont work. I must have corrupted something.
I hit the tune icon, it tells me to put ignition in "on" position, then I get a black screen with the little turning dial. Then the dial freezes, and ...

30 minutes? Man I guess the days of a 5 minute switch are over. I'm not sure that's worth the trouble. Are we talking if I install a tune, 30 minutes, then want to go in and adjust parameters, that would also take another 30 minutes?

Thanxs bighorn, guess I'll git er done!

I got this "This vehicle requires additional tuning before a Diablo tune can be installed"? I backed off from there until I can confirm this is no big deal. I had this tuner for my 2012 R/T, and never got this msg. before. Any feedback would be appreciated.
This is for a 2013 Charger SRT8

Any 2013 SRT Chargers out there Install a tune? I'm that guy that always waits til the bitching subsides, then I know its safe
But I got an itch that wont go away, should I or shouldn't I?

Take your time, I want it right the first time, ofcourse I'll still sit back and let the "gotta have it now" crowd iron out the kinks

thanks Mike, glad to hear it!

I just need a confirmation here.
I traded my 2012 RT in on a 2013 SRT. But I been sitting on my dcx in anticipation of a future tune for my 2013 SRT.
Am I good here or will the 2013 require a completely different tuner? Just need to know if I should sell or hold on?

I restored my backup tune to my 5.7L Charger before I traded it in. So I thought I'd use the tuner on my kids 3.6L challenger, but when I plugged it into the chally it said I have to get some update, which was odd, because right before I went out to the car, I did update the tuner.
So I then went ...

I thought I read my tuner was unmarried once I restored back to the original backup. But I cant seem to use the tuner on my other car. What am I missing here?
