Can you walk me through how to get started here. I am buying a new ECM/PCM for this project. I am blindly assuming I need the MPVI4, smart access cable, and VCM Suite to extract the existing OEM tune then I send that and the new ECM/PCM to HP Tuners for the unlock. When I get it back I contact you about a new tune.

The hard downshifting I spoke of earlier might be better described as overly agressive engine braking. It isn't that is downshifts "hard", it is that it does it too soon and causes excessive and abrupt engine braking.

You’ve got it. Since you’re buying an extra PCM, best bet is to install the new one and have it programmed and set up at the dealer. I guess if you want to guarantee the OS is the same between the two, your old one will need to be checked for updates. I’m not sure if HP Tuners would do the cloning for you. Might be worth asking.

Then you’ll make your big purchase on their website. Go ahead and get your credits too. Then I would ship your old one to HP Tuners after your new one is installed and running. Doing it that way, you don’t need to get a read on it before sending it off. I do mine all on one order, that way they will send you everything back in one box all together.

Once you are ready with everything in hand, I can assist you further with any other intricate things you might have questions about. I often use TeamViewer and remote into people’s computer all the time while talking over the phone to walk through the process. Once you do the process once, the subsequent revisions are super easy and quick.

Failed to mention, when you purchase the unlock service, there is a button for uploading your stock tune. You do not have to do this. That’s for people who order a replacement GPEC2A only and not something they offer on GPEC5.

As you can tell, I am totally new to this whole thing. Tuning in the past has been 1) buy a device, 2) hook it up, 3) press a button to install.

Are you saying to install the new ECM then get towed to dealer to get it programmed? It won't run before programmed, right? Or should/can I send the blank one to be unlocked, install it when it gets back, and load a tune on it myself? Can I read the tune from my original unlocked ECM?

All good, your actually the first person I've worked with who has wanted to have two PCMS involved. I believe HP Tuners does not clone GPEC5 computers. It may be worth calling them and asking directly to find out.

Typically, they receive a PCM that already has OS and VIN number with it. They crack it open, do their unlock service, and send it back to you. That is how I and the dozen other customers I have tuned thus far have done it.

Is there any particular reason you want a clone PCM? You can return to stock at anytime with the click of a button on your PC.

I'm going to draft up some condensed instructions in word and post it up here shortly, more Youtube videos coming too

 

[Badunit]

I got it so 1) I wouldn't be without my truck while the ECM was in transit to/from HP Tuners, 2) I'd have the original if the new one never made it home, and 3) as a fallback in case I somehow brick the new ECM. But it sounds like I have added an extra layer of complexity to the process.

It's all good! I can definitely understand why people would want to do it. I just don't want to give out bad info since I've never done it personally.

Maybe try reaching out to HP Tuners to confirm the process. I would think they need a PCM that has already been programmed with your VIN and has the latest OS from the dealer before they unlock it.

 

[Badunit]

I'll ask them.

SO HERE WE GO, ANOTHER LONG POST

If you don't have anything purchased yet, here is what you need to get FROM HP TUNERS, NOT ME, as explained in that JL Wrangler forum thread:

-MPVI4 ($400)
-Dodge 2018+ Smart Access Cable ($80)
-PCM Unlock Service ($250, not needed if you want transmission only tune)
-HP Tuners Credits
GPEC2A - 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.

Just FYI, by purchasing an MPVI, you will have access to other things like check engine light diagnosis, transmission adaptive reset, rear diff gearing changes, tire size changes, power steering disable, and more as HP Tuners adds more features. Those are the ones currently available in addition to the tuning.

Since I'm new to this forum, I won't post pricing, but pricing is listed on the JL forum. DM me on here for questions. I am very responsive.

Trans Only Tune

-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 Tune

- Fixes the annoying low load low RPM stutter felt between 1500-2000 RPM.
- This stutter was caused by the way VVL and VVT are activated and used from the factory.
- Better throttle response from revised cam settings.
- No datalogging needed unless there is an issue.
-Any octane fuel can be run.
- No need to datalog
- Everything else is bone stock

-Complete Daily Driver Tune

- Includes the stutter fix
- Will tune for whatever octane you want to run. 87 octane will have stock spark timing minus a few minor changes due to EGR tuning. Higher octanes will have more spark and cam advance for more midrange and top end perforamce. Initial datalogging shows 20 HP gain on 91-93 octane and a shift in torque curve more towards the low RPM range. Dyno graphs to come in the next few months.
- FREE 87 tune included if your primary tune is for higher octane that way you have something to fall back on if needed.
- Complete engine and transmission tune with datalogging before and after to
make sure your Jeep is running good.
- Cam timing and VVT operation revised.
- Dramatically enhanced throttle response, no more spongy throttle
- Torque management changes to put power to the ground better
- Deeper customization upon request for throttle response, fan settings, stop
start permanent disable, etc.

The full tune is a dramatic night and day difference in your ride. It is what I recommend the most.

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

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.

I've already tuned three of these in the past two days, plus my own. I'm sure some good reviews are forthcoming.

Thanks!

You didnt say anything about having to buy another PCM or send off your PCM to be unlocked . So how is this accomplished.

I did mention PCM unlocking. A quick browse on the HP Tuners website will reveal this as well.

Sorry, I've already discussed this in about 10 pages of posts on the JL forum and don't come over here as much.

You dont have to buy another PCM, just send out your existing one. That is the PCM Unlock service for $250 noted in that original post you just quoted. I am about to publish an entire how to for first time users. Stand by

Read the attached guide, this will assist in getting you started. Any further instruction will come through me via email once we get started in the tuning process.

What years this cover? Mines 21'

All of the 3.6 Gladiators. Your 21 should still have a GPEC2A so will be less credits needed.
