Hello DS

A little background
- I am a long time user of DS products, especially trinity (I have 3 of them in use)
- I am documenting this as much for me so I can relay all information as I am stuck and will need to phone in the morning for sure

- 2015 Charger Hellcat

Last fall - did some mods (new SC pulley, intake, driveshaft etc)
- bought unlocked ECU & custom tune from a well known vendor (came with a trinity)
- trinity backed up original tune (from the unlocked new ECU) and I loaded custom tune no problem (as I have done many, many times, car ran great all fall and even as early as today)

Fast forward to today
- Pulled car out of 3 moth storage to pin the crank - big job, but got it done
- started car I the garage and it ran fine (with my custom tune still in it, didn't even mess with anything on the trinity at tis point)
- took a shower and decided it may be a good idea to check the DS site for any trinity software updates, gage layouts etc - turned out there was (1r13h, I think I was g)
- went ahead and restored original backup to the car and proceeded to my computer with the trinity
- plugged in the trinity with DS downloader running and it updated automatically as expected
- back to the car, I knew I has to read original backup again so I selected 91 oct dS tune for 6.4L in order to force the tool to read my ecu which it did (there is no 6.2L option, I did this last fall as well) and it said it was successful
- I then hit ok and the trinity loaded the 91 oct tune on the car (remember for the 6.4, not the hellcat 6.2). I think last fall I cancelled the tune write after the original backup was read and proceeded to load my custom tune, not sure), this time it wrote the tune to the car

PS - I did notice that the "h" version froze a couple time just booting up and I didn't pay much attention. It kept going to a screen "new registry" and I hit continue when it asked

- back to the computer to load my custom tune on the device, says it did (although it seemed fast).
- back to the car - unit freezes as soon as I hit any button, if I plug it in the computer it shows not married. - I can't retrieve the backup tune as the unit says it doesn't exist and constantly freezes up in the middle of operation. I can't figure out any pattern

A couple notes....

I do have my original backup tune on my computer from last fall as well as my custom tune.
- car currently has the 91 oct DS tune for a 6.4 on it and of coarse the car won't start at all (different setup altogether from the 6.4)
- I do have the original locked Stock ECU for the car. I supposed I could use this to get the car mobile but I want to speak with DS first before doing this. (this ECU does not support my mods anyway and hasn't been plugged in for over 5K miles so the mileage in the ecu is incorrect.

I am dead stuck, and hopefully I can get this resolved quickly . . . . .

Update - Just came back from dinner, plugged the trinity into computer to see if I could read original backup 1 last time, unit now says "Problem: press the center button..." when I do it says "filesystem error". when I hit continue it just reboots to the same messages endlessly . . .uuuugh . my kitty is getting angry not being able to start !! Hopefully tomorrow will be better. . . .I should have just left it alone instead of trying to update it . . . . . . . .I should have known better

the tool cant load a 6.4 tune, the vehicle selection does not determine what tune is loaded, it determines that by talking to the pcm.

If the tune loaded ok the car should start fine, will the tool still communictae or allow you to restore the stock tune?

Thanks for the reply Mike

Tuner is stuck on - "error press center button" then "filesystem error", won't boot, nothing
PCM did not flash correctly on car, and car is dead

Spoke with Garrett today, he was helpful

PCM and Trinity on there way to DS under RMA

Put stock PCM back in car and it fired right up although it doesn't support my performace mods and cannot load custome tune as it is locked.

Thanks to DS for getting me through this, pretty stressfull for me but the support is really terrific so far.

Its my first time with any issue with any DS product in over 10 years of using them on multiple cars . . . .


I will post updates as I go.

Thanks again guys

Update:

Unlocked Hellcat ECU and Trinity were delivered 03/30
Waiting on response, RMA 89186

Update

Received new trinity and reprogrammed ECU under RMA

You guys at Diablosport are truly fantastic, Thank You

Now I have to get my Hellcat out of storage and try to install my custom tune. Problem is winter is not giving up, snowing this weekend. uuuuggg

I just not sure if the PCM was reflashed back to stock (hellcat) and if my custome tune is still compatible

I will install PCM, save original backup, send to my CMR tuner alog with my previous custom tune and see if its to upload it into the car to make sure CALID's match etc

DS - Does this sound right as a course of action as there was really no instructions that came back with my PCM

Thank You

Randy


PS - Trinity automatically updated to "h" rev level when plugged in. DS - Is this a known good release as I don't want to go through this again

The H release has bugs for other models but for the hellcat , who knows

Update

Received Re-flashed ECU and installed into car, car started up ok

Did an original backup, process went fine

Yes, the cals are the same, should be all set.

Update

Thank you mike

Custom tune loaded without issue.

I Beleive my troubles are now over, car runs great.


Deepest thanks to the entire DS team!

Randy
