Is the: u7137-9t12c.crom - still the latest and most up-to-date tune out there for the Jeep Wranglers 3.8?

Thanks!

It seems to have taken the CROM you linked me to, and then I updated to the newest CROM ... just did the calibration and it should work!! Thanks again!

GREAT TooCool!! Thank you!

OK, I don't get it. I can't upgrade to the latest tune to my buddy's Predator U7137 for the Rubicon JK.

I says: "Can't downgrade u7137 from 9r09 to 9t12c"

Can someone explain it to me? This Predator is new. I've been on HOLD now for about 25 mins ... I may have missed the hours.

Thanks

HOORAY!! Can't wait to try it out! Thanks!!!

Yea ... that's exactly what I did. After discovering that loading the zero tire pressure and tire size didn't seem to work so well loading it INTO the program ... I did just as you suggested and loaded it by using the Quick Adjust AFTER the tune was installed. It loaded and all appeared to be fine ...

Same write failed here with 9t12b. It will install with no mods but when I try to modify I get write failed and install original backup. so now I am back to stock.

Glad to hear I am not the only one this happened to! I was worried that my JK was a 'late Friday afternoon' build or something! LOL ...

NJROBSRAM .... that was the message I kept getting too. The only parameters changed (on my Jeep JK) was the throttle boost(11%), tire size, and setting the tire pressure to ZERO ... write failed then made me reinstall stock tune.

MIKEL ---- any progress on this latest tune issues?

[quote="amw"]Just wondering if I load this revision to my Jeep if the tire pressure threshold will enable me to eliminate my "spare pressure low" warning by setting it to "0"? BTW, I don't have a spare anymore... [quote="amw"]

That was my plan too ... didn't work so well. It's a great idea though ...

I am only guessing that the Predator for my 2003 F350 7.3 is the older model too? Mine doesn't even have a model number on it - just "Ford 7.3" on a white round sticker.
Are you guys still charging the $99 + $23 to ship?? Don't I get veteran points, long time customer appreciation award points, or ...

Mike/Frank,

Hey guys ... we spoke on for phone for an hour or so last week about my 2010 Jeep JK Sahara 6spd using this latest tune. It kept crashing as I added the third change in parameter. Well ... I dealt with it and tried to suck up the fact that I couldn't modify the TPMS (tire pressure) down ...

Mike - THANKS!!! I missed the latest revision that changed that.

One more thing (if you're looking) - Did you guys find any tune that identified a Cold Air Intake, aftermarket free-er flowing exhaust, or the VIPER throttle body?? Would that be a custom tune or are the tunes good enough to ...

Latest revision

Just wondering if it will be possible (or impossible) to deactivate the TPMS in the Jeep JKs? Whenever I change from winter tire set to the summer tire set - I get the beeps and the Tire Warning Light.

Can you please help me to deactivate the ...
