Flashcal F5 -vs- AEV Procal

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.

What did you choose and why?

Thanks!

The FlashCal only turns TMPS on or off. no adjustments.

Straight from their website---

  • Speedometer Correction
  • Tire Size - 26" - 42"
  • Axle Gear Ratio
  • T-Case Gear Ratio
  • TPMS On/Off Available (Download Required) Adjust Feature Only Available On TrailDash/TD2
  • 4WD-HI Axle Lock
  • Speed Limiter - No
  • Idle UP
  • DTC Read & Clear
  • Internet Updateable

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.

Great point. I also don't want anything permanently installed. I just want to attach, change the Jeep's behavior, detach.

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.

As I mentioned in another thread, don't buy the Flashcal for the locker-in-high-range feature. It doesn't do what you think it does.

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).

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 like the idea of the Flashcal/paq but have decided to go w/ the Procal (for reasons similar to the above).

Thanks all!

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...

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.

I will promise you that it's more than a 1mpg loss when going from stock to 35's. More like a 2-3 mpg loss.

We'll see. The 17 to 18 was highway miles on the same trip I did a month ago getting 18 to 19. Next week driving around town will be the real test.

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.
