Using the Black Maxx interface you can monitor up to 16 parameters in real-time: from Boost Pressure & Gear Position (AUTO) to Fuel Rail Pressure (ICP) & Intake Air Temp. Other Chevy/GMC 6.6L Duramax parameters available to monitor:

  • CURRENT POWER LEVEL
  • PYRO 1 & 2
  • ENGINE RPM
  • COOLANT TEMPERATURE
  • THROTTLE PERCENTAGE
  • TRANSMISSION TEMP. (AUTO)
  • LOAD PERCENTAGE
  • DEFUELING STATUS

The Pyrometer connection is NOT necessary for the Black Maxx to function correctly. It is used for gauge display and for one of the defueling parameters. It will NOT harm your truck to run without a pyrometer probe installed. H&S Performance does, of course, recommend purchasing one for the 6.6L Duramax LML so you can monitor your Exhaust Gas Temperatures and set your defuel levels based on EGTs.

This is a Race Only product used solely for competition. Its use is limited to closed-course racing that is formally sanctioned by a recognized racing organization. Any other use, including recreational off-road use, could be in violation of local, state and federal laws. The Black Maxx is not legal for sale or use in the state of California.

6.6L Duramax LML Black Maxx Specific Notes

  • Power levels are NOT shift-on-the-fly. It may take up to 10 minutes to change tunes. Check here for software updates. This also means the Black Maxx will NOT defuel on its own. A built in warning showing “WARNING PYRO 1” or similar where it would normally defuel.
  • The EGR and UREA main harness must be unplugged, while the DPF Pressure Sensor must remain plugged-in to gain full horsepower when running in DPF Removed mode. Instructions for these requirements can be found here:
  • Periodic emissions checks are performed by the truck’s PCM. While doing so the dash may display “Service exhaust fluid, see owners manual” if the the vehicle has recently been reflashed or has not been run in a while. This message will clear itself as soon as the emissions check is complete and can be ignored. Check here for software updates.
  • Tire size is NOT yet adjustable. H&S is working on an update to add this in a future software release. Check here for updates to this issue.
  • The Speed Limiter is allowed to be removed but will cause loss of cruise control functionality. The Speed Limiter is capped at 96mph. Until an update for this issue is available, the choice to go over 96mph or to use the cruise control is yours to make.
  • Exhaust kits right now are ONLY available in CAT back kits. This is due to the extreme embedded nature of the down-pipe. For those who have a shop or the ability to cut, modify, & weld to get to this area, the LMM Downpipe Kit can be modified and used.

Please Note: This tuner requires the use of a race exhaust system.

Important Note: This purchase price includes the cost of the 6.6L Duramax LML software unlock code part 111006. When ordering, include your complete VIN # in the “Order Comments” of your shopping cart. Your unlock code will be emailed to you.
