Disappearing tune?

Post by TNPete »

This is really for Mike L as he gave me a (what I presume) is a beta update for my inTune, and a special tune he made specific to my Charger...
So I doubt this will really effect anyone else but me... but Mike is not taking PM's :)

In another post I pointed out that I couldn't disable Traction Control on my 2015 V6 Charger.
Apparently there is an issue with our 8 speed tranny that is giving the inTune a problem disabling TC.
Mike offered to make me a special tune to disable it on my system.
Later he also gave me a update for my inTune to fix the problem with with the 8 speed tranny... Hence what I assume was a beta, but I was fine with that, I'm a software engineer and have used a lot of beta's (and alpha's).

Well it "worked", after installing the "beta" my device no longer threw an error when disabling Traction Control.
When I started the car the dash complained that I needed to get service for the Anti Lock Breaks, and the Traction Control, I told it to stuff it's error messages :)
I'm aware that traction control is just the computer using the anti-lock feature to hit the brakes if your tires skid, so that message wasn't surprising.
I even took it for a little test drive and it was running sweet!
I even came back and posted how here about how happy I was...

However, on the way into the office the next morning, I noticed that the Traction Control was enabled again... and the "BRAKE" message was gone too...
What's more I didn't have the same "get up and go" that I had since getting my inTune...
I have no proof that the entire tune was disabled, but it sure felt that way...
Well as a software engineer I was perplexed... Does the PCM have a 2nd internal copy of the default tune that it restored?
What's going on here? Where did it get a copy of my original tune? I was pretty confused...

Anyway the next day I had an appointment, before leaving I re-ran the exact same tuning I did before:
I selected Advanced Tune & choose the "Diablo Tune" (same as the 93 Octane Tune).
Set the Throttle to 15% (it had an asterisk next to it, did that mean I had changed it before?)
Disabled the Traction Control (it had no asterisk)
And finally I installed the tune.

All was well on the way to the Doctors, my Charger was charging again :)
However, after the 30 min appointment, when I started the car again, the flipping traction control was again ENABLED... :(

OK, so this time I decided to try the modified tune that Mike had made me.
No options chosen, just installed the tune he sent me.
Traction Control is disabled again, but now so are the air bags... or at least I'm getting a warning to service them...
When starting the car I get the warning messages about servicing the Air Bags, the Anti-lock brakes, and the Traction Control...

I've restarted the car numerous times now, and at least this tune is not "disappearing" on me, but I have to wonder about the air bags...
I thinking that should probably have those air bags operational, especially now that I have no traction control or anti lock brakes... :D

I'll attach the info.xml and last tune written from my device...

Thanks in advance,
Pete

PS. If it would help the engineering team with debugging, I can use the disable TC option under Advanced and send you all the "Last Tune Written" from my device.
I'm sure they are trying to disable TC in the released branch of the software... if it would help I'd be glad to give you all the last tune written from my device after using the menu.
The attached Last Tune Written is going to be from the tune you sent me, NOT from the disappearing tune after using the advanced menu...

tc disable is not permanent since it disabled ABS, its designed for only one key cycle.
You can use the tune I provided with TC disabled to have it stay off all the time when that tune is loaded if you wish.

Tune on the PCM cant change, its flash based, erased first then written, so theres nothing to 'go back to'.

Thanks Mike,

Yea the engineer in me knew that it couldn't possibly just revert to an old tune without a flash command.
they COULD get that sophisticated, but it would be a lot of effort for a small subset of us flashing our PCMs...

So, for the air bag warning message on start, is that just the PCM getting confused when the TC is permanently disabled?
I'll ignore it if everything is kosher...
I wasn't getting that with the "one key cycle" version the advanced option gave me.

As for my perceived loss of power, that was obviously all in my head :)
I was thinking that something had gone wrong, so in my head I was feeling that I'd lost power that I had not.
Besides, rush hour traffic is not the best place to judge HP :)

thanks again,
Pete
