Trinity 1000

Ram-engineer · Dec 26, 2016

Well I was excited to get my Christmas present the Trinity package with pcm for the 2500 6.4 truck. However this thing did not disable my Eco mode when I requested it to do so. It did not calibrate my speedometer for the new tire size either. I updated the damn thing too.. I have emails into Diablo see if they want to help with this issue or not. Yes it did show that the tune was written to the new pcm and all that too before anyone chops off my head.

The eco light will still come on even when MDS is turned off, so there may not be any issue there.

Nah, you can hear it bog down even like it always does when in Eco mode

There is no such thing as eco mode though. The eco light is simply there to show you that you are driving correctly to get the best mileage. The MDS system is what shuts it down to 4 cylinders on the highway. The eco light is always going to come on whether the MDS is on or off. Mine is disabled in the tuning, and I even switched to non MDS lifters, and the eco light still comes on anytime I cruise on the highway at lower rpms.

If you think it did not disable the MDS even though you did turn it off, then I would return it back to stock and then reload the tune again. Then after the tune is loaded, do into the quick adjust settings to correct your speedometer for the larger tires.

Do your adjustments after you have loaded a tune.

I had exactly the same experience. Based on my experience, I recommend not holding your breath while waiting for an answer from Diablosports. I went ahead and posted an inquiry to Hemifever at Dodge, Jeep & Chrysler Tuning | Jeep Chip | Dodge Programmer & More | Diablo | SCT. Sean answered me back within hours! He offers a "preloaded tune upgrade" that will disable the MDS. You can order and pay at Hemifever preloaded tune upgrade. It's all done by email. I began the process late this morning and by 2:00 PM, NO MORE MDS. I think it's worth mentioning that his tune is a few steps beyond the boxed tune from Diablo. Seat of the pants says that anyway.

Sean did a wonderful job with my custom tune as well. One of my requests was to turn off MDS and he did it. No worries, no issues.

Looks like I will be in contact with him in a few days. Diablo fixed the issue I have to load a tune for a 2015 2500 and it all works now. I would still like to get more out of it then a boxed tune with this 93 I can tell a slight difference from stock nothing major. 0 to 60 little better by little more than .250 seconds.

yeah, the "canned tunes" are nuthin' to write home about. I got my first custom tune about 8 or 9 years ago on a 300 SRT8. It was a real eye opener compared to the standard Predator 91 octane tune.

Glad to hear that Diablo took care of the issue. Just curious. Does the 6.4 have MDS? If so, is there an option in any of the menus in your tune to turn off the MDS?
