I’ve been researching this topic for a while now I have a 2015 challenger hellcat and I’m starting to get tired of the infotainment system as it is very laggy and slow. I wanted to upgrade to the new RA4 or Panasonic Uconnect system however for the 2015 model year we’re required to change the pcm and go to the dealer if the dealer even decides to flash a used pcm along with losing some crucial features like heated steering wheel it all seems like too much work and not worth it in 2022. Does anyone know of any solution I may have missed to upgrade this garbage Harmon Uconnect on the 2015 or some module I can plug and mirror my phone or something I really wanted that CarPlay feature. Thanks!

Where did you hear a new PCM is needed? I believe with a Tazer you can do the necessary update to the BCM to enable the newer Uconnect unit. There's a company out there offering retrofit kits as well. You will need a new USB hub in the console for CarPlay I believe too.

I believe what your mentioning is only for the 2016s but correct me if I’m wrong.

2015 and 2016 and got better in 2017. OP, have you updated the software in yours?

 

[SuperSound]

Seems like the 2017 model (maybe 2016 too) could be software updated. 2018 it became standard, but I think the 2015s need another unit entirely.

Here's the site I saw about converting for reference:

Holy crap, for $2400, I might as well wait for the Daytona EV to come out and get it for free!!!!!!

I think it’s still running same software from 2015. Is there a way to update?

Ok found something that will help. It looks like 2015 and 2016 can't do the software upgrade, only 2017 cars.

[UPDATE] 8/15/22 - Thanks to the awesome work of James Howard in the comments for getting the developer of Alfa obd involved it seems you can now skip step #3 completely and will no longer be required to take a trip to the dealer. See James Howard's comments in page 3 of the comments for more...

Yes, I saw this however it’s a lot of work and expensive with no guarantee all the functions will work properly. It’s a gamble I’m not willing to take hopefully there’s a new solution in the near future. Some told me to just get a newer model cat but I don’t see a point it’s the still the same shit with minimal improvements.

Much cheaper than the infotainment site I posted earlier at least.

I know Tazer can do the same thing AlfaODB does in this kind of swap. I would send them an email to ask how and what is needed. The issues seems to be just the 2015s, but maybe they know what to do about that.

I doubt there will be any other solutions coming. Modern infotainment systems are far too integrated for the aftermarket now. The OEM keeps making small changes to stuff which makes retrofitting near impossible.

Speedy just did a swap for this. Look at his youtube channel.

Use that Tazer at your own risk! I went to David Starnes here in Memphis to fix my trans. He said, and I quote, “Get that f** thing out of your car”

He has a 2016.

He has a 2016.

Was there a difference between 15 and 16? I don’t believe so. The swap would be the same. USB plugs in the glovebox and the head unit.

There is the pcm and programming is apparently different in 2015.

Tell me more about this. I have been planning to get one (I have one in my Rubicon 392). What EXACTLY did he say was the problem?

 

[LarryH]

I was talking to him about there being more to the ZF90 shift schedules then just what’s stored in the TCM and PCM and that was his response. As @SublimeCat15 stated the control module’s ALL talk to one another. You have a manual trans car so no shift scheduling or torque management issues for you. Did you know the ZF90 cars are using artificial intelligence to tune virtual clutches? Clutches that do not exist. Not in this universe. That’s what “tq mngt” does. How sure are you that the BCM doesn’t play into that equation?

Thanks. Just so we're clear... I have an auto trans in my Rubicon. I have not personally experienced any powetrain/driveline issues since installing a Tazer, and certainly none that I know are attributale to the Tazer. I am fully aware that all of the modules in modern vehicles communicate and as a former GM engineer, I even know HOW some of them do that. That said, there are specific paramaters about which they communicate and others about which they do not, depending upon the system at issue. What I want to know is not what his "theoretical" issue is with the Tazer, but if he has any real world experience with specific issues that he (or his clients) have experienced that were unequivocally tied to the Tazer as opposed to any other mods or tomfoolery going on in the modded car. I do not assume that the Tazer could NOT inject such issues, but I have not heard/seen real world evidence that it, in fact, does. That is precisely why I asked the question.
