Custom tuning for your Cummins in Real Time
 Take control of your 1998.5 through 2018 truck


     The MM3 is based on the Smarty Touch hardware platform, but the similarities end there. MM3 is dedicated to the custom tuning market and the professional tuner. The MM3 can be considered an “Open Tuning Platform”. It comes “blank”, meaning it has no tuning software installed. It has it’s firmware, all drivers, communication protocols, ECM unlocks, human interface, Real Time capability, etc. installed. It is designed to be able to load tuning software files from the UDC Pro and from a variety of different tuning softwares. Upon request from the manufacturers of the tuning softwares, it can be easily adapted to load tuning files in any format. Given that the MM3 is a blank unit, ANY performance tuning HAS to come from a professional tuner. Simply put, the tuners build the performance software and the MM3 allows the tuner to get his software into the ECM. All working principles like, get stock file, send files, ECM files, Real Time Group, and Real Time Parameters are the same as with a Smarty Touch.


Tuning 'levels' - this is how we break down how much to charge for a truck with given modifications.

Stage 1: Stock Injector, Turbo and CP3.

Stage 2: ONE of the following modifications: <= 125 HP Injectors, 10mm or smaller CP3s and <= s369 single Turbo

Stage 3: TWO or more small modifications: <= 125 HP Injectors, 10mm or smaller CP3s and (<= s369 single Turbo) or (<= s475 in compound kit)

Stage 4: TWO or more MAJOR modifications or conversion trucks (swapped motors, trans, bodies, etc.): Injectors, CP3s and Turbo any combo

 ***Truck must be scheduled and put on our calendar for initial tuning***
