Thanks for the info. Nice to know it won’t set the code. Too bad it won’t work in a 2021 model.

Additionally, will installing the original PCM in the 18 challenger set the P1400 code?

Haha! No, 18 challenger to 21 challenger.

Thanks. It’s for a 6.4 challenger.

Can an unlocked PCM for a 2018 6.4 6-speed be re-vinned to use in a 2021 6.4 6-speed?

Thanks for the reply Mike.

I know this an old thread, but just wondering if there are any plans in the works for single use CMR licensing. I would like the ability to get a little deeper into modifying things that the handheld can't do, like part throttle spark and fuel, and maybe even mess around with cam timing.

No, I know that, but I mean after I get my custom tune, can I just up the idle a bit, on top of that custom tune? And then can I save that increased idle tune as a separate one?


Yes, I have modified versions of custom tunes loaded as new custom tunes. When you modify the custom tune by raising ...

I was looking at the logs and it looks like the throttle is closing when I shift into gear. Why does it close the throttle when shifted to drive or reverse?


thats a standard torque reduction move. eliminates harsh gear engagements, etc.


With the stock tune it looks like it opens the ...

So, why don't any of the canned tunes work? If the vehicle is no longer supported, just say so.

I should clarify: With the 87 tune installed, when shifted into gear it looks like it is closing the throttle more and more until the engine stalls. If you look in the log you can see the engine RPM going up and down until it just stalls out.

Tried loading the 91 tune and the screen went black and the I2 rebooted and came up in recovery mode. It restored everything back to stock and is no longer married to the VIN. I'm almost ready to give up on the idea of tuning this vehicle.

Spoke with tech support a few weeks ago and they targeted my device for an update. Ran the update and nothing has changed. Here are logs of the stock calibration and the 87 tune. 11287_03.log 11287_04.log
And here is the info.xml file

I unmarried the tool and tried again. Still nothing ...

Connected the I2 to the computer and ran the updater. Device updated and I tried running the 87 tune again. Nothing changed, engine still stalls in gear. Installed stock calibration and all is good. Device is still married to the VIN, just running the stock tune if that matters.
