Hi,

Is Flex tuning possible on 2015+ Hellcats?

Supposedly the flex tune programming is there in the PCM and is available with HP Tuners. Curious if flex tuning was also possible with Diablosport. This will allow 93 to E85 gas and everything in between to be used without changing tunes (with the ...

Long story short, I went out and did 15-20 minutes of data logging, doing several WOT pulls, saved the damn file and yes I made sure I hit the "Yes" button when it asked to save.

Got home, plugged in the i2, and the f'ing log file is nowhere to be found. Why the fuck does this happen every now and ...

Hi,

I attached the backup, the last tune written, and your last TCM tune (6350 file name). The last tune written file will reflect the canned diablosport TCM performance tune, as I only run the modified TCM file occasionally and run the canned tcm performance tune for daily driving.

So right now ...

Logs do seem to verify that its shifting a little past 6200, not sure why but theres a lot of math to get these shift points changed, its not like some older stuff where you just type in '6350' and it uses that value :)

Hi Mike,

Thanks for the TCM update that raised my shift points. I'd like to ...

I have the same issue but I thought it's because the I2's cannot see or use 5Ghz routers, only 2.4Ghz. Even if you run in hybrid 2.4/5Ghz mode the device will not see it. This is true for alot of other (older) devices.

Does the new i3 recognize 5Ghz routers now?

That kinda sounds like Johan who couldn't figure out why some things were ...

Hi,

Finally got a chance to test out your TCM tune. I have to admit it took me a while to work up the nerve to install this after all the TCM transmission issues I went through previously.

However, I loaded this up and I didn't have any transmission issues at all. Drove a few miles and the car ...

Thanks,

I will give this a try. Is the shift point raised for just certain modes, like Track, or is it across the board? A

Certainly, was on a brief vacation.

Attached are the files.

I also reached out to other tuners and so far none of the big ones are offering Diablosport TCM tuning to customers, including HHP..
Did you not see my post above? I have raised shift points. No problems.

Brent Hughes DTP Racing?

You are the only one on Hellcat.org that has a working TCM ...

we helped HHP run 8.80 through a stock 8L90 yesterday with TopCat, there's definitely nothing wrong with the software ;)

Have you talked with Johan about the suggestions Jay Greene Provided here?

Why did you have to help HHP in the first place? Why couldn't they fix whatever issue they were ...

Updates?

Attached are all the TCM tunes I went through before me and Johan decided to stop any further tuning because of the issues I was having.

Attached are logs of the PCM tuning with the Diablosport canned TCM.

Diablosport's TCM tuning is garbage. Should have never been released.

I tried TCM tuning with Johan but always ran into issues, such as yours. Would either get stuck in gear or refuse to shift.

Having issues now with even the canned TCM tune. The top of 4th/5th gear now skips/skids like the ...
