Diablosport (Holley) has the PCM available up to 2023/2024, available adjustments below, I will be going with Throttle Response, MDS off, Speed Limiter removed, and Tazer JL Mini so I can run RWD Only eliminating the 4 wheel Auto...was hoping Diablosport would add RWD Only option that would have been perfect!

Get that puppy to the dyno!

in all seriousness… we all know the 6.4 is capable of 500+, would be curious what the Diablo can do.

Keep us posted on how she drives!

I am wondering the best route to do this while preserving my original ECM. Would I start by buying this? 68480920AC
And then just unlock and tune?
Mirror off of original first?

In for the results. Wish there was a bit more straightforward way to get A tune. Mainly just want to get rid of the power dip and have a better shifting trains

Get rid of the ESS (Auto Stop/Start), Speed Limiter, and a little more throttle response would be great, hopefully they will come up with a RWD only option as well...I don't see TPMS, but I am sure it has it....going to call them Monday when they open and get the low down, will revert back with findings...

The 392 doesn’t have ESS.

Have you tried running in Off-Road+ mode?
With my 2023 XR, the 4-cylinder mode is locked out when I'm in Off-Road+ mode.
Good luck....
 
Update, talked to Rick at Diablosport, they already have the 2023 Jeep and the PCM Program is in process...good news, no MDS, no Speed Limiter, increased throttle response, and Tune if you like...would be nice if they could add RWD on/off....will ask Rick to request that as well....

Ok they are going to also delve into RWD only option discussed with two members of their team...they said it was an EXCELLENT idea...should save the wear and tear on the MP3022 clutches.....

Have diablo change the fan temp settings and then you don’t have mess with the t-stat. 210 is a much better temp to start the fan and be full at 220.

Cooling Fan Control is included...you can set the High/Low Temps....

Will they be changing the shift logic as well?
