EFILIVE Cummins Tunes

** 2022 NOT SUPPORTED AT THIS TIME 

There are a few pieces of information we need from you and your truck to successfully build the tunes. Please ensure the information you are providing in this order is correct. If not, it will cause the turnaround time to increase greatly.

Please note: Due to the way the Cummins are flashed, it is not possible for us to adjust the tire size with EFILive. If you have a bullydog 40420, you can use that to set the tire size on all the Cummins trucks in the special features without having to load the bullydog tunes. 

INFO WE NEED:

• VIN Number and tire Size (if tire size is different than stock).
• Auto or Manual Trans (Required if CMB/CMC truck, if newer we can get it from the Calibration ID)
• If it is a 2010+ truck we also need the S/N and E/C number as taken off the ECM. Or if you rather the Calibration ID from the OBD window as well as the SN. Feel free to take pictures and attach or manually type the info
• Please specify the tune(s) you are looking for; most common tunes are
• 06-09 Cummins (CSP5) 0hp Stock 25hp Tow 45hp Economy 75hp Street 90hp Race
• 2010-12 (CSP5) 25hp Tow 45hp Economy 75hp Daily 90hp Street 120hp Race
• 2013+ (CSP4) 45hp Economy 75hp Daily 90hp Street 120hp Race
  
  

What's the difference between CSP switching and CCV switching? 

• A- CCV switching is DEFUELING a single tune's HP level from 5-1
  CSP switching is ACTUALLY switching between tune maps (tow,eco,street, ect ect) on the ECM. CSP switch plugs into the OBD port and the CCV switch plugs into the CCV sensor. The reason we offer both is because CSP switching wasnt available for the 2019's only until a little bit ago. 
  
  

**WARNING** 2018+ Cummins:
NEED SPECIAL 3rd Party Tools to Use EFILive on the 2018 + Cummins. Without a bypass cable, you will not be able to successfully tune your truck.
