HP Tuners for 3.6 models - Fixing what Jeep won’t

[bmpcamry09]

I'll be reaching out once I get the tuner & unlock completed. Thank you!


Any possibility of supplying a TCM only tune for the 2.0L as well?

Yep I can TCM tune the 2.0 as well!

I've got two 2-doors for some insane reason, a 25 3.6L manual and a 26 2.0L auto. The auto in the 2.0L really has terrible factory shift logic.

Other than the unlock credits, will the single tuner be able to be used on both vehicles?

Yes sir, and you can just transfer the access cable between the vehicles when you need to change something.

I really dont know, sorry, I just can see that flex fuel OS capability is already enabled on my 2025, dont know if it has an alcohol sensor or if it just picks up on the swing in fuel trims and assumes alcohol content.

Here are a few screenshots to show you what I was talking about. Flex fuel is a click option and its already populated in the OS, and all alcohol related compensations in the tables are already generated throughout the file

,

Looks like it might be a virtual sensor.

2018 through 2026 3.6 Tuning available!!!

Thanks for sticking with me guys, didn't take too long!! After 40 plus revisions, 3 tanks of fuel, 800 miles of driving, and lots of cussing, I am pushing out the first batch of tunes. 91 and 93 octane "performance" tunes are yet to come and still in development, but what I have ready to go will suit 95 percent of Wrangler owners.

For those who have already got their PCM unlocked and MPVI device and are ready to go, here is what I am offering right now.

-8 Speed Trans Only Tune - $200

-Cleaner crisper shifting, reduced shift times, less shift slop
-Less clutch slip = longer lasting trans and better temp management
-Better shift schedule, much easier downshifts, no more engine bogging
-Can customize shift schedules and shift firmness to your liking.
-Datalogging not required unless needed to fix an issue
-PCM unlock technically not needed, but recommended as there could be
datalog issues.

- Stutter Fix Only Tune - $200

- Fixes the annoying low load low RPM stutter felt between 1500-2000 RPM.
- This stutter was caused by a conflict between intake VVT timing and the
the EGR system. EGR remaining active in this file.
- Cam timing upgraded for better midrange response and feel
- No datalogging needed unless there is an issue.
-Any octane fuel
- No need to datalog
- Everything else is bone stock

-87 Octane Daily Driver Tune, $400 for Automatics, $300 for Manuals

- Includes the stutter fix
- Complete engine and transmission tune.
- Retains stock ignition timing, any octane can be used.
- Cam timing upgraded, but less aggressive to allow for any octane.
- Greatly enhanced throttle response, no more spongy throttle
- Torque management changes to put power to the ground better
- Datalogging recommended for first file to make sure your Jeep is happy.
- Deeper customization upon request for throttle response, fan settings, stop
start permanent disable, etc.

If you don't have anything purchased yet, here is what you need to get FROM HP TUNERS, NOT ME, as explained in prior posts:

-MPVI4 ($400)
-Dodge 2018+ Smart Access Cable ($80)
-PCM Unlock Service ($250, not needed if you want transmission only tune)
-HP Tuners Credits
GPEC2A (18-22) - 2 Credits needed for PCM, 4 additional needed for TCM
GPEC5 - 4 credits needed for PCM, 4 additional needed for TCM
-If you are a new customer and buy a new MPVI4 plus 6 credits at the
time of purchase, your unlock service will be FREE!!!! Not sure if website
automatically applies this discount, so you may have to call or email
HP Tuners to confirm.


Remember, I only provide the tune file and I do it all remotely through email, it is on you to buy the MPVI4, Access Cable, and PCM unlocking.

I will likely have same day turn around once you supply me with your read. I am abnormally responsive to emails and DMs because I HATE unread notifications on my phone. I'm a bit OCD about that. LOL

Payment will be through Venmo or Paypal.

Be warned, I WILL make you sign a liability release form before supplying your tune. My files are tested and safe and used in my daily driver. I have tuned hundreds of vehicles and never had a single issue. But at the end of the day, I am just a nerdy car guy who knows a lot about tuning who does this on the side, so it's to protect me. If you don't like that, sorry bout cha! If you are worried about having a "random" guy calibrate your vehicle, look me up on HP Tuners forum and look at all the nerdy crap I've developed with some of the pros over the years. Or DM me and quiz me. I'm ready

Additionally, I will be locking the files I send to you. You will not be able to edit them or see the changes. This is to protect my work. Tune theft is a thing in the HP Tuners world unfortunately. However, if you want to know the tables I tune on, I am more than happy to send you screenshots of the comparison log. I'm not afraid to show what I change like some guys.

The process with me after you have everything purchased and ready is as follows:

-DM me on here for my email address.
-Tell me what tune file you want and give me your $$$$$.
-Do a "Read" on your PCM and TCM, Save your file, back it up, and email it to me.
-Email me your MPVI serial number and VIN number
-Sign a waiver
-Get the tune back from me.
-Flash the tune to your Jeep.
-Enjoy your refreshed ride.


THANKS FOR TRUSTING ME AND STICKING WITH ME THROUGH THE PAST FEW WEEKS. I'm stoked at how much better my 2025 is driving and can't wait to hear some feedback and review. If your not happy about something, email me first because most tuning related things can be datalogged and revised.

To any admin people watching, let me know if I need to remove pricing information.

Thanks!

-Brad

Nice!!!! Standing by for your performance tunes (91), but looking forward to it.

Awesome work your doing.

Not really wanting to send my original pcm out. Could I purchase a new blank from Jeep send that to them along with my vin#. Or would I need to bring it to a dealer have them program it for my vin# then send it out?
68568654AB is what I show for the part# and it is pretty cheap at only $130.

For that small added cost I would much rather keep my original stock and use the backup to play with.

If not addressed since, yes, I bought a 22 PCM to hopefully be able to disable MDS in OR+ because my pre XR 21 didn’t. Benny’s price was ~ $200 cheaper than Mopar MSRP. Dealer install along with the NoLimitz at NC “Before you do something desperate”. The stock one now available for a tune after warranty expiration.

@alphawolff - may I ask what 392 tune and reason?

I can do the 392 models as well guys. I've done a few Scat Packs, they tune the same way, actually I believe the Wrangler 392's are derated compared to the others.

Great, but the big question for me, CARB approved ? Also, I have “no tune required” ported stock intake manifold and TB to 88mm, the gain with both is just slightly higher than the TB alone with a tune, (also AWE catback). can you tune appropriately ? Someone told me the net 15Hp difference was due to less accessory loss due to electric accessories not tune but I don’t know if correct.

I live in BFE Midwest. CARB out here is short for carburetor. No idea if it would be or not. Doubt it. The last scat pack I did I added like 30 degrees of part time cam timing which probably isn’t emissions friendly. lol.

Would probably need that one in person. Neural Network will probably have to be trained which is a process and I’m not very familiar with it. I’ll probably stick to stock 392 builds.

The story of this Ca residents performance wants. Heck, even the headers made here “Not currently CARB exempt, can’t be shipped to Ca” and currently for about 3 years so far.

I'm assuming the Stop/Start permanent disable means the start/stop button is effectively useless and can't turn it back on? Not saying I want it on, but just curious on the side effects.

Correct. The button becomes a dud until reactivated in the tune.

To be CARB approved the tuning would need to be kept the same for each vehicle and then a sample vehicle put through a certification process, which generally costs around $25,000 and takes anything up to a year for the ARB to shuffle papers around. If you are lucky it could apply the multiple configurations of the same type but probably you'd be looking at V6, 392 and 2.0T all separately. 49 state is easier but you still really need to do certification testing unless it was something like just a change to the radiator fan settings. That's why so many manufacturers don't ship to CA - they do a quick 49 state assessment and skip the costly and lengthy certification process.

If the catalyst is retained, emissions related DTCs are not disabled, cold start ignition is not changed then emissions are not going to change. Leaning out at WOT and adding a little timing doesn't change emissions. Cam angle changes generally don't change emissions as long as they are not extreme to the point of getting into an area where the factory did not tune well. Changing EGR volume will possibly change emissions, but my feeling is that when the tuning is so bad there is a misfire then cleaning things up will result in an overall reduction in emissions. EGR reduces NOx but increases HC so it might depend on where the manufacturer is closer to the limit.

Engine tuning doesn't automatically make the engine dirty. We supercharged a vehicle and it went through CARB certification and that vehicle was the cleanest vehicle test ever seen by the ARB. ARB did not believe the result and so took the vehicle to their own lab, with the same result.

Here is a screenshot of the infamous "hiccup" from a datalog on a stock tune from a 2024 I am tuning for a forum member. This is seen multiple times through the log, caused by false activation of the VVL system and bad cam mapping. See the yellow line dip? Thats intake cam suddently shifting, the dip in spark timing is right there with it. There is the proof of the issue Jeep refused to address.

 

[bmpcamry09]

Here is another video I made explaining the hiccup/stumble issue in depth and discussing VVL operation. I discovered during development that the "high lift" VVL mode is ONLY used at part throttle light load to supplement efficient EGR operation. Activating of high lift forces the intake cam timing to advance. This causes a sudden spike in cylinder pressure, resulting in an immediate pull of timing. All this coming together at once is why your 3.6 is stumbling like mad at light load light throttle.

My tuning as described above fixes this. No need to have high lift at all. It's never used at WOT. It's only used at part throttle. Instead, we can modify cam operation in that same range so you still get great throttle response and low torque, and then we can modify EGR flow so that we aren't overwhelming the combustion process with exhaust gas, however keeping the system active so you meet emissions.

Hit me up for a tune and get yours fixed!!!

I’ve had several forum members ask me about the higher octane “performance tunes.” I am going to update the post that has all of the tune description information in it because as it turns out the high octane files are going to be built off of my regular daily driver file.

Essentially, you’ll buy a complete tune from me and I can build you one for high octane and I’ll also supply the 87 file for free that way you can switch as you please. This is custom tuning after all, and I would rather make a data log and make sure the timing changes are safe for your vehicle rather than just hand out a one and done file.

Initial testing is indicating about a 20 hp bump with 93 octane based on my data logs. I won’t be able to get to a dyno for formal graphing for another 6 to 8 weeks. Once I do that, I’ll post something up.

The main difference between the premium fuel tunes and the 87 octane fuel tune is spark timing and intake cam timing being advanced for higher cylinder pressures. The premium fuel tunes will have a little bit more mid range, torque and top end pull, but it’s not that dramatic of a difference compared to 87 in my testing. All of them are dramatically better than stock.
