I'm need to buy one of these this week. I have a 2015 JKUR (HR). I'm mostly interested in doing the following:
1. Teach my jeep about my new tires (getting 35s this week or early next).
2. Daytime running lights. I have JW Speaker Evolution Js.
3. TPMS. I want to lower the nag threshold from 37 down to ~20. I do still want to see all readings (not just have them read as 0s).
What I've gathered from other threads is:
1. Flashcal F5 has a nicer interface (not dip switches like the Procal).
2. Some people have differing results on #2 and #3 above when using the Flashcal.
I chose the ProCal, and it does exactly what you're asking for. For TPMS, it can set several different pressure settings, as well as disable TPMS.
The dip switches are simple to deal with, just follow the provided chart, which fits nicely in the glove box manual cover.
One deciding factor for me, was that the FlashCal actually flashes the computer(IIRC), while the ProCal is simply changing settings.
I am also looking into one of these. One thing to consider is that some of the advertized features on the Flashcal require the unit to be plugged in to work. I don't want to have a 3' cord attached to a hand unit swinging around my clutch pedal while driving. I sent them an email requesting more info, but havn't received a reply yet.
Not sure about the flashcal but the flashpaqs can do pretty much anything once you set the tune or whatever your using it for you can unplug it. The only time I ever leave mine plugged in is to read engine and transmission ,temp
and revs while driving, and if I am winching someone you can control idle speed with it as well. If your considering the flashcal you might as well spend the extra $150 and get the flashpaqs. You want be disappointed. I originally had the aev procal for a few days until I saw all the extra features the flashpaqs had over the flashcal and procal. The tunes and extra readings for engine are why I chose to get one and sell the procal. The tunes do make a difference in how well your jeep shifts and drives.
I'll be getting the traildash 2 in the near future.
FYI: I just called Superchips. The only feature which requires the unit to remain connected is allowing lockers to be used in 4hi.
He did confirm that they only support TPMS on/off on their flash products today. Changing the threshold is in their Traildash product. I already have a touch screen in the Jeep (I replaced the factory headunit w/ an Insane Jeep Audio JK1001). I don't want to have 2 touch screens sitting there.
I guess for me, it's coming down to how much I care about TPMS threshold -vs- just on/off and how much I care about a product that I can upgrade later (flashcal to flashpaq upgrade).
Maybe on the newer flash products, my older one which is a 3872 flashpaqs for a 2010 model just so everyone knows, I can adjust the thresholds it. Maybe the F5 hasn't got update yet.
I have used the AEV Procal on multiple Jeeps with zero issues. Super simple and works instantly. Seen multiple threads about Flashcal isues. Procal for me!
i used aev procal no issues at all worked right away. Just make sure you put your key in the on position but not actually on and running so don't crank it up.
AEV ProCal for me; You can Adjust TPMS low Tire Pressure Threshold down to
22 PSI and still have your tire Air Pressure read out on the Dash; You can also
Disable the Factory TPMS , ( should be used for off road use only ).
So not to hijack, but what kind tuning is available for the 3.6? My F150 EcoBoost is tuned & it's felony fast even on 91 pump, but it's also a twin turbo. I have the SCT Livewire TS+ & thinking that might work in the Wrangler too.
I was contemplating the same thing recently. I had originally decided on the FlashCal but I started reading the absolutely stellar reviews of the Flashpaq on Amazon. I decided to spend the extra money on the Flashpaq 3872 ($279 on Amazon) on the fact that everyone stated better performance AND better mileage!
The reviews were correct. I have a 2014 Wrangler Sport with 3.21 gears, manual transmission and I'm running 33's. Not only did I experience what "feels" like a performance upgrade (no dyno data to confirm this) but I did get a quantifiable gain in gas mileage.
Prior to downloading the 87 octane performance tune I was getting 12.7 MPG with the 33's and no speedometer correction. After adding the Flashpaq tune and adjusting for the proper tire size I am now experiencing 17.0 MPG. I don't know what the exact MPG would have been if I only adjusted for the correct tire size and did not add the performance tune, but I do know I was getting 17.6 MPG on the stock tires. My driving habits have not changed and these numbers reflect about 90% city and 10% hiway driving.
The money saved on gas mileage alone is worth the cost of entry in my opinion. From what I understand, the performance gains are much more noticeable on the automatic transmission as the shift points are adjusted to accommodate the larger tires. Bottom line, calculating savings based on $2.00 a gallon gas and driving 12,000 miles a year, adding 4 MPG (13 to 17) will save you $434 a year. If you think that MPG gain is impossible, how about going from 13 to 15 which will save $246 a year and even a measly 1 MPG gain (13 to 14) will net $132 savings in a year with gas at $2.00 a gallon and 12,000 miles a year.
Don't take my word for it alone, read some of the 180+ reviews on Amazon. I was skeptical but I took a chance and I believe the Flashpaq will easily pay for itself in the long run.

silly question, but if you had no speedo correction, how were you measuring MPG? were you using a GPS?
ie if the speedo is wrong, then the odometer is wrong, therefore MPG, either calc'd by the jeep or manually is way wrong...
fwiw I like my flashcal F5, nice color screen, seems to work ok... seems ok overall... flashpaq wasn't an option due to cost for a '15...
So I have a '16 JKUR with 4.10's and an auto. Switched from the stock 255/75r17 to duratrac 285/70r17. Will a Procal make a noticeable difference for me?
I have a AEV procal. Live in Maryland south of Baltimore. If anyone needs to change settings and doesn't want to spend the coin, we can meet up. I only bought one because I only have one friend with a jeep and he doesnt have one. I doubt I will ever use mine more than once in a blue moon.
The Procal binds to the VIN and can't be used on more than one jeep without clearing the settings back to factory in the original jeep. I'd take you up as in in Montgomery County and just had to buy one. It got here today so I plan to calibrate this weekend.
Are you kidding me, there are more benefits for the 3.8 than with the 3.6, mainly setting your shift points correctly and retuning the engine to accept the higher octane gas and burn it correctly. Believe it or not those tunes make a difference not only in how and when your jeep decides to shift in and out of O/D, but even a crawl tune specifically for when your off-roading.
I went from the stock tires ~32s to 35s that are more like 34.5. My jeeps readout was around 13 mpg. With the procal, all it did was correct the speedo. (Manual tranny) It is now at ~17+. I did not gain any mpg - it only corrected the calculation. The 13 was using bad data and was a false reading. Correcting the speedometer fixed the data and the 17 is more true.
So based on this and the previous readings, if figure the 35s lost 1 mpg at the most.

Yeah that's where you'll lose the most in town. Long trips vary depending on the terrain, how hilly or flat the road is. I can drive to the beach in mine and get 17.5 mpg. I can drive to the mountains and get 15.
Just hooked a Procal up to my '16 JKU this weekend. Corrected the speedometer against GPS +/- .5 mph. Running 35" BFG KM2s (36lbs) on 17" AEV Saltas with the Mopar 2" and with 3.73 gears. Onboard computer is showing 17.9 MPG with 50/50 city/highway driving right now. Highway only was showing 21 MPG on the trip meter reset.
I have the flashcal F5, the one click lane change only clicks for about 4x, I was under the impression it would be until I made a turn or am I doing something wrong? Those of you with the procal is until you turn or a couple clicks also?
That just an software update? I don't have a programmer for my JK yet, but buying something this week. More than likely the Flaskpaq.
BTW, anyone know what's the deal with changing the 2015/16 ECU? What am I looking at for cost & effort?
