2010-2018 Cummins CCS MM3 Custom Tune Files

What does the Transmission tuning do?

TCM Tuning increases the line pressure, this puts more pressure on your clutch packs and prevents them from slipping which can cause excessive early wear on 68RFE's clutch disks. It will also change the shifting points to match the new tuning which helps improve the overall driveability.

My truck is heavily modified, will this tuning work?

Yes, we can have these tunes written to accommodate any modifications that your truck may have. We just ask that you state any modifications in the "*MODS" script box. We will have the tunes written according to what is in this box, so the more information, the better!

Can you modify my existing mm3 tune to accomodate the non vgt turbo change I have made?

Yes, your existing tune can be modified to accomodate a non-VGT turbo./

looking to pass emissions what tune do i need

To pass emissions, you need a stock or emissions-compliant tune, but if your truck is deleted, you will need to restore emissions components first.

Can you enable high idle features in the tunes for a 2013 ram cummins

Yes, high idle can be added to the MM3 custom tune.

So I have a 2012 6.7 Cummins and going to be putting a non vgt turbo on it. Will I need to get a custom tune or will it work with the vgt tunes

Yes, you would need a tune or the truck will have warning lights surrounding VGT issues.

Do I need a SOTF with the mm3?

If you want to switch between different power levels while driving, yes.

Hi I have a mm3 tuner with a drd custom files on but I ceep on getting service exhaust see dealer codes will you be able to correct this if I send you a log file or something or cannyou direct me to somebody whom can donit for me. I bought a few parts drom you guys but not the mm3 tuner

The "Service Exhaust" message typically indicates an issue with the tune or emissions system. Checking for DTCs, reloading the tune, and logging data can help resolve the problem. If needed, contact us at tunes@dirtydieselcustoms.com and we can help you troubleshoot!

I have an MM3 installed in my 2015 6.7 and am wondering what information is required to be able to get custom tune files?

We require the following:
1) VIN #
2) Tune Level selection (if purchasing a single tune)
3) Any modifications your truck may have (EGR delete, bigger turbo, Injectors etc). The tunes will be written according to what is inputted in the "*MODS" script box, so the more information the better.
4) Tire Size
5) Stock read file.

Can these custom tunes be used on a RaceMe Ultra? After more modifications are made?

Yes.

Already have MM3 tune from you guys but now wanting transmission tuning. Do I have to pay the full $650?

Are the lope and whistle tunes available for a 2012 6.7L

Yes

Hi. I was wondering if these custom tunes will work with a 2019 ram?

You bet! These will work on any Ram with the 6.7L Cummins.

if I order all tunes does that mean I can re-tune as needed with no additional charges? and how many tunes does this give me?

If you order all tunes you will receive multiple tune levels (Stock, Tow, Street, Performance, Race). Once purchased you can reflash your track as needed without additional charges. Custom revisions would need to be purchased at an additional cost.

Can you write this for a 2014 Ram 5500 C&C?

Absolutely!

If I already have a mm3 installed on the truck and it was done by a different company. Can I buy the file tunes and just install them into that. Would that work?

You'll need to supply us with a stock read file of the truck, and then we can write the tune files for you.

What are the HP/TQ for each stage on the tune? And would I be able to use this tune if I delete my truck for off road operations.

Level 1 (Tow): ~45 HP / ~100-150 TQ. Level 2 (Daily): ~75 HP / ~200-250 TQ. Level 3 (Performance): ~90-120 HP / ~300-350 TQ. Level 4 (Race/Hot Street): ~120-150 HP / ~400-500 TQ. Level 5 (Max) ~160HP+ / ~500+ TQ.
