Finally got the modified PCM installed, flashed and functioning. New to Diablo - been around Caterpillar engine & transmission ECM's - flashing and configuring for quite a few years. Thought I would be OK to delve into this install with the information given on the website. NOT!! The information in the manuals on this website, plus 99% of what's in the forums out there do not pertain to the 2015/2015 Ram PCM.
After spending the better part of the afternoon on the phone with various levels of DiabloSport tech support, performed a forced cal ID download/upload & finally got the Performance 93 Octane tune flashed.
The main reason I purchased over $900 worth of this stuff for my new truck, was to disable that aggravating damn MDS. On a good day, going downhill, the MDS might give me (and FCA CAFE statistics) 0.5 mpg.
Now, after all this, the option to disable MDS isn't on any of the menus. My calID is: 68265839AF. My vehicle is correctly configured as described in the subject line.
Under Performance - Diablo Tunes - Perf93oct - Install Tune - Modify Parameters, the items available are:
Cooling Fans
Idle
Rev and Speed Limits
Throttle
Tire Size
Traction Control
WOT Fuel
WOT Spark
That's it. Nothing... anywhere under any of the other menus about MDS or active fuel management. Nothing about transmission shift points. Quite different than the capabilities described elsewhere on this website.
Someone please help me out. Do I need a "custom tune"?
Thank you.
