The flashpaq wouldn't be something I could run without comfortably . I have used it on an '11 jkur for 3-4 years ? to set gear ratios , tire size for 35s now 37s , shift point firmness , rpm during winching , and I've only run non-Ethanol 89oct for the life of this things 83k . I use the 90tune .
I can also monitor temps and spark retard or knock settings , cat temps, map sensor IAT,coolant, auto-tranny oil temp,set the fan to cut-on at a specific coolant temp ,egr functionality as well as other data that the Jeep won't give me info on other than a dummy light on dash ....
Lastly , it is a feature of the device that at 1st configuration it saves your stock OEM ecu settings for every function or PIM it can access in a ' stock tune' archive file that you can restore- back to ( & also save elsewhere if you know what your doing ) if you ever need to*. No trouble , only positives , on my ownership . Worth the painfully expensive money, I sggt it to anyone starting to modify a Jeep JK / JKU as one of your first purchases.
<edit: *I did not get to look at the link about someone's story of having to replace the ECU but there have been those that do not RTFM or jump in and do not save their stock setup first and can have issue with restoration to OEM settings. Not sure if that is what that link involves, but just follow directions and I have not heard of any neg experiences
