Reprogramming Gladiator Mojave for 35’s?

[ShadowsPapa]

I bought my stuff on Amazon -

This is the security bypass cable -

This is one type of OBDII Bluetooth adapter -
https://www.amazon.com/gp/product/B06XGB4873

I actually prefer this bluetooth adapter for certain settings, but the above one works for tires, etc.
This one is faster and can access some of the deeper stuff (jscan describes some of this on their site)
https://www.amazon.com/gp/product/B07JFRFJG6

I have JSCAN and another software package that is amazing, but more expensive - AlfaOBD.

If you have multiple FCA, RAM, Jeep vehicles, etc. AlfaOBD can be used on all of them with just one purchase.

Unless JSCAN has changed, you buy 1 license per vehicle VIN - so if you use it on 2 vehicles, you need two licenses. But it's a great product all-in-all.

Actual tire size varies, even when the numbers on the sidewall are the same. I have used this site to get the sizes of specific specific brands and models. They list both diameter and reveloutin per mile.

Tire Size Comparison

I just switched fron the 285/70r17 Flaken Wildpeak MT that came stock on my gladiator to 35x11.5r17 Toyo AT tires.

Wildpeak - 32.8 dia - 634 RPM
Toyo - 34.5 - 602


The error rate seems to be ~5%, measued by GPS and also as claculated.

I haven't noticed any difference in how my truck drives.

if the speedo is correct so will be your shift points so in theory not really a performance enhancement but changing the shift points to act what stock would be with stock size tires makes it drive much more better not sluggish like when you put bigger tires on without a programmer if that makes sense

Shift points are also determined by load. Throttle position and manifold pressure. Putting larger tires on a Jeep effectively makes the gearing taller, so load will be higher for a given gear/rpm (indicated speed). So shift points should automatically adapt if you put on bigger tires.

The fact that it isn't shifting into 8th with your 37s on stock gears isn't a bad thing at all.

On the Jscan site, it has a pic of this one but doesn’t mention the JT below it. Do you know if this one works with the JT?

Yes, it does work with JT.
I have that one and it works - fine for tire size changes and the sort of thing most Jeep owners would access.
It's the one in the link I posted earlier. Not sure why JT isn't listed, but it works.

What all would I miss out on if I get this one instead of the $100 one?

I was "messing around" in jscan and hit these two - but I do not know if there are others, or if these are even important unless you were doing something major. (see pictures below)

Here's what my wife has said to me over and over, and I still don't always listen - "if you dare come home with another cheap version of XXXXXXX, I'm sending you right back to get a better one".
I went through 2 circular saws - she sent me in after a better saw. So I didn't tell her I bought a cheaper adapter and then later ordered a better one - she didn't notice that small charge on the card WHEW.

Are these necessary to ever access? Dunno - I was messing around, snooping, learning my way around jscan and the gladiator settings. I do better by digging and learning by snooping and looking around and trying things.

So far the only thing I have not been able to do with jscan is one of the settings for auto high beam. I like AlfaOBD a bit better, but then, I tend to dig and go just as far as I possibly can on things - it's just how I am.

Thank you!

I thought Mopar had an App for different tire sizes. I was scrolling through the touch screen and saw something to do with tire sizes.

Tazer can.

Had mine done at the dealership just for a piece of mind. Didn’t want to use a J scan or Tazer. I’ve heard that if they want to, they can dig deep enough and see that one has been used, not sure how true that is. Plus the fact that the dealership has record of them doing it and my service guy said that if I ever go to 37’s that he would recalibrate it for free.

 

[ShadowsPapa]

Tazer can.

Yeah, so can JSCAN and AlfaOBD with this adapter. (pic below)
It's not like the software can't access it, it's the difference between a $25 adapter vs. a $100 adapter.
I can access all things with the better adapter below.
On the other hand, if all a person wants to do is the tire sizes and common or basic settings, they save a ton of money using jscan and the $25 adapter. 50 bucks and they've got it. No need for fancy expensive hardware.

I can access all things with jscan or AlfaOBD and this adapter - including those spots I showed in the screen shots.
The cheaper adapter just isn't fast enough or able to get to some areas.

You must UNmarry the tazer and remove it - otherwise it won't leave a trace because if it's not there, all it does is change settings in the system's menu. Sure, they can see things have been changed compared to bone stock, if they really want to spend their hourly rate digging, but the tazer doesn't leave a footprint, and jscan or AlfaOBD are simply software that goes in, shows you the choices built into the PCM, BCM, etc. and lets you select from what's already in there.

The dealer I've been using gave me a choice - they'd sell me the devices to do the job or they'd do it for me - and charge with each change.
I opted for the software route because it's useful to me - I can use it to diagnose issues as well. My choice.
In your case there is a record of the dealer doing the work so if you are someplace else and need something done, that work the other dealer did pulls up in the VIN.

I added passive entry to mine. I asked if the dealer shop would contact Jeep and have that sales code added to my VIN. That way with any reflash it wouldn't disappear and I've not have to put the settings back. I was told there'd be a charge for that. Made sense, it's not warranty work, it's a change. They not only called Jeep and got that sales code added to my VIN, but they also then downloaded the new configuration for my VIN from Jeep, flashed my truck to make sure it was really in there, tested functionality - and charged nothing. Maybe it helped because I told them another dealership had failed to get that box checked when I ordered the truck LOL. (which was TRUE)
Now when I log into the Jeep site and choose my vehicle, it shows that passive entry was added by the dealer. Well, technically it's right and wrong - I put in the parts, and programmed it, they added it to my VIN.

I just want to turn off auto start/stop, and turn on my rearview camera when I use the turn signal.
Can both of those be done with Jscan or AlfaOBD?
I'd like to be as cheap as possible, and that means no tazer.

No. The camera is a live feature of the Tazer. It's a great investment.

Both are live features of Tazer as they are not software selections in the programming.
That means tazer must be installed and left in place to work.

I've been thinking of grabbing some wiring diagrams and see what it would take to trigger the camera with turn signals.
As far as auto stop/start, you don't need to spend a dime for that - push the @#$%@ button.
You push a button to start it, you move a shifter to start moving - just one more event in the sequence of events you go through every single time you enter your truck and make it move.
It's free - push a button. After a week or two you'll do it and never give it a thought.

Otherwise, I know there were a couple of people on Youtube that came up with a cheap circuit to do that for those who are too lazy or forgetful to push a single button once before driving away - their circuits cost something like 25 bucks. one was installed on a Grand Cherokee. Same system so if it works on one Jeep it will work on any Jeep.
