I guess that's what happens when marketing writes copy and doesn't have the technical people review it.

So if I am reading things correctly, the new ZF-8 Speed Transmission Tuning only supports Grand Cherokee SRT8 and not 5.7 models?

Well, as I stated before, my 2016 5.7 Grand Cherokee was scanned at the dealer and came up as having the 'tuned' code.

"...We have resolved this and all PCMs shipping from here as of last week will not have this code."
What about those of us that have that have older PCMs. How do we get the P1400 out of our vehicle's system?
Two months ago I went to the dealer to get my 2016 Grand Cherokee's air conditioning ...

FINALLY-
I had to ship my Trinity back. 2 days later they called and asked for the PCM back. After about a week, I received them back on black Friday...almost made thanksgiving.
Of course no information was sent but I powered up the Trinity from my pc and found it had the latest 1r13e crom, had been ...

So, yet another week of nothing new to try. I have been at this since late September....maybe it will work before Thanksgiving.

Soooooo..last Friday I called in again, got great help, he sent me the latest CROM - dcx gas 1t13eb.
I loaded it, went to the Jeep and got the same failed result.
Was told they will work on it, but still nothing works and I am in a holding pattern again.

To try that for the third time, I will be happy to call you guys again...has anything changed???

Interesting idea, but the family's other two vehicles are not on the tunable list (2016 Cherokee & 2016 Renegade) and I wouldn't want to risk shutting anyone else's vehicle down.
And the response from DS is ...(cue sound of crickets chirping).

Just trying to load the canned 93 octane tune. No I didn't add anything to the Trinity, just updated using 2 different computers (thought windows 10 might be a problem so tried my old field laptop windows 7...no difference). No SD Card in my Trinity. Just as it came out of the package plus my ...

That was October 11.
Now one week later and still I have $1000 worth of hardware that doesn't work.
I guess that "engineering staff" must be really busy.

At least you got yours to work once, I can't get past the first step of saving the original tune to even load any of the canned performance tunes.

Well, 4 days have past since I was told "Our engineering staff is looking into this". I even tried using a different pc to update the trinity, and got the same failure to save original tune. I think the release for the 2016 Grand Cherokee was premature. I'm wondering if anyone else bought one for a ...

Thanks for update
