Would all you 2013/Auto/35s people with Procal or Flashcal PLEASE reply to this thread telling us which gear your rig is in on level road with cruise control set at 28 mph? To determine which gear it is in, wait 10 seconds for it to settle into it's chosen gear, then manually shift down one gear, read the gear number inside the "D" on the instrument panel display, then add one to that number. Mine runs 4th gear at 28 mph and the motor luggs.

I have the Auto w/3.73's. My 13 ready Procal set everything and the transmission shifts up and down as it should. I have not experienced any lugging issues. When I leave home I do encounter a 55 mph highway and I immediately start up a 2 mile long uphill pull with a gain of at least 700' ft elevation change. The one thing I did noticed is under load in 3rd gear on a long steep grade it does not upshift to 4th until you totally let your foot off the accelerator and let it upshift. It will still pull in the hill in 4th gear just fine, it seems like it hesitates upshifting in this case. I do not know if this was the case with the 255/17's when it was stock. Otherwise it seems just right. I only set cruise out on the highway at 55 and above and the transmission works perfectly.

Update regarding my issue where the auto tranny upshifts then luggs while cruising: After reviewing the issue with AEV, I told the dealer and they drove it and said "everything is fine". I asked them if they followed my suggestion and cruised at 28 mph to witness it shifting into 4th gear and holding it (and lugging)...they said no. I asked them to reflash it, in case the "adaptive learning function" had picked up behaviors while running the previous (smaller diameter) tires. My hope was that, after reflashing then adjusting the speedo using Procal, the computer would begin shifting and controlling the torque converter properly. I am very happy to report that IT WORKED!! I drove it 5 local miles yesterday and 12 local miles today and the issue is resolved! I don't know if the adaptive function will change the shifting behavior over time, therefore I will drive it 300 to 400 miles then report back here on the results.

just a shot in the dark but even a stock newer jk will do this if the fuel is at 1/4 tank or less

That could be the cause, since I currently have less than 1/4 tank, however it is not occurring consistently. It happened 3 times in a row earlier this week, then it did not occur the past three times I did the remote start. I made no changes in-between.

One of the features of the Superchips Flashcal is
Engine idle adjustability for winching
Has anyone tried this feature and does it automatically adjust the idle when the winch is under load?

I got this response from Superchips...

If you connect the device to the vehicle, you can select the feature to keep the idle up when winching. Once the tuner screen is changed to a different feature or is unplugged, the idle will fall back to stock.

Dumb question maybe but tire pressure. In the manual it says adjust for max tire pressure, and the sliding scale on the flashcal go from 0 to 75. I've already downloaded the tpms override or whatever it is from the online store and updated. Can someone explain what I'm missing in idiot terms or how to use this feature for when I air down?

Lots of guys talking about lugging. But how does it affect how the Jeep runs? More power, better response? Any noticable improvements?

It assists you while re centering the steering wheel, which can get off center from adding a life or wheeling. I believe it work by turning on or flashing the headlights when the steering wheel is in its center position.

Roger. Just read the instructions on the AEV website. Should have done that first.

I just put on 35's, so I figured that I should get the Superchips Flashcal to calibrate my speedometer. This was yesterday. What I've noticed is that my engine revs as I accelerate. At approximately 40 MPH, the RPM's race up and keeps going up until I let off of the gas pedal, then it drops down to around 2000, and is fine after that.

Another wierd thing, my gas mileage is now up 19.8 mpg, from the normal 16.5. This is after putting on 35's. Someone help me!! The gas mileage and engine rev makes me lose faith that my speedo is even working correctly. Anyone with knowledge of what's going on, please respond. Thanks in advance.

When you increase tire diameter from stock to 35s, your speedometer no longer indicates your speed accurately and therefore your computer (which uses your speedometer reading to determine when to shift) no longer shifts at the correct point. This will not only throw off your speedo and your shift points, but also your MPG calculation. To correct this, you must use the AEV Procal or Superchips Flashcal to recalibrate your speedometer, which will correct your shift points. One thing I will mention, based on my experience doing this (with 4.10 gears on a 2013 Rubicon with dual top and max tow), is that the Procal and Flashcal do a great job of correcting the shift points on accelerating, but when you are doing less than 50 mph and you cruise at one speed, after 6 to 10 seconds the transmission shifts up to the next gear (assumedly to improve MPG) and this causes the engine to lugg slightly. The only way to avoid the lugging, that I am aware of, is to regear from 4.10 to something higher. I am waiting for AEV or Superchips to fix this issue but they have not resolved it yet.

I have a 2013 with 4.10 auto and 35's corrected with the Flashcal and have not noticed any difference except that I do get a little better gas mileage now. Did you enter 35" or measured tire height? They could be quite different and can make a difference.

I entered actual diameter with the weight of the Jeep on the tire. It came out to 33.5 inches (for my 315 duratracs). I tried both Procal and Flashcal and experienced the same results with both.

Would u pls do a quick test to help me troubleshoot? Would you set your cruise control at 30 mph then wait10 seconds then read your tachometer? Pls tell me the tire diameter that you entered into Flashcal, the tach reading, and which gear it was in when you read the tach.

Here you go, this is a video of me doing the test as you wanted and a pic of my cluster on cruise at 30 mph. I have another video cruising at 30 and then accelerating out of Eco mode and speeding up with no bogging or hesitation. If you want that one I could post. Also have a pic of cruise at 40 and 60. Let me know if you want that info.

As you can see 1300 RPM at 30 on cruise and ECO is on. When I hit the shifter it goes to 3 so I was on 4th and on Eco.

Are you certain about this? I have read that the computer uses engine speed to shift rather than vehicle speed.

I have a 2013 JKUR w/3.73 auto on 35" tires. I do not like the way it shifts either. It has not been recalibrated.

Do you feel like your 4.10 give you a good ratio or does it still feel underpowered? I'm considering 4.56.

I can tell you what my experience has been: After calibrating my speedo, my 2013 auto with 4.10 gears, 315 Duratracs, and AEV 2.5 accelerates great and handles great. I will not need to upgrade to 4.56 gears, as this setup has worked great for me in so far with 4,000 miles of commuting and some tough wheeling in mud holes, sand dunes, steep climbs and a swamp. If you have already decided to swap gears but you aren't sure whether to go with 4.10 or 4.56, I would suggest 4.56 if you do mostly city driving or tow often and 4.10 if you do mostly country or highway driving and tow occasionally. This is because with 4.10, when I cruise at speeds below 40 or 50 mph, the tranny shifts up to the next gear to save fuel, causing the engine to lugg a little. The vibration and noise is a little annoying. If you do mostly country or highway driving, you will rarely experience this issue and you will get better gas mileage with 4.10 gears. If you do mostly city driving, it would be nice to have 4.56 gears to help avoid the lugging and provide a little more torque as you are constantly speeding up, slowing down, and shifting.

Thanks! This is the dilemma I am facing: 4.1 for highway or 4.56 for everything else. 3.73 is not horrible, it's actually fine if you're deep into the skinny pedal. It's when you're driving moderately, when it shifts down at <3k and drops below 2k that it feels sluggish. This engine does not like to accelerate from below 2k. It'll cruise there just fine, but if you need to do anything fast - good luck.

I'm getting great gas mileage with duratracs 315 70 17, 4.10 gears, procal is finally dialed in , banks cai, and banks monster exhaust, aev 2.5 lift. Jeep has plenty of balls, I was worried I wouldn't be happy and have to regear but no way, it rocks

Thanks for the video. I tried to replicate your run at 30 and found that my rpms are almost right where yours are, so that gives me some assurance. When I increased throttle, however, mine held on to 4th gear much longer which might be why I notice lugging while cruising.

I like the 4.10 and after calibration I improved in gas mileage. It has plenty of power but like ALL vehicles now a days you may have to punch it. Remember they are trying to meet federal mpg requirements and guess how they do it. That's fine with me, when needed the power is definitely there. Also mine is a daily driver in the city.
