2016-2023 GM 2.8L LWN Tuning

A comprehensive tuning option for the GM/Chevrolet Colorado and Canyon with the Duramax 2.8L LWN engine. 

This tuning is supplied via the HP Tuners TDN Network which operates on an iOs or Android smart phone.  Wifi, bluetooth and a car battery charger will be required. 

If you do not have an HP Tuners MPVi4, please add one. 

Credits are sold separately. 

Choose Your tuning, single tune file or multi tune file package (all files). 

Performance levels listed below are all at the crank. 

0hp (optimized stock)

12hp (heavy tow)

24hp (light tow)

36hp (sport)

48hp (performance)

60hp (race)

Anything over the 24hp file makes transmission tuning mandatory. 

Off road tuning, requires an race exhaust and canbus plug cap kit.

Engine Calibration

• SOTF with cruise control buttons 6 tunes no switch required
• Increased throttle response (reduced or elimination of dead pedal)
• Increased torque in all power levels which allows earlier shifts when applicable for improved fuel economy
• Increased fuel economy due to optimal commanded fuel quantity, injection events, timing, and trans calibration
• Quicker response to driver input due to transient fuel, timing, VGT and Transmission calibration
• All safe non aggressive OEM detune / back down strategies are left intact or calibrated for the higher power levels that prevent premature failures
• All limiters that are safe to be removed are
• Exhaust brake memory and maximized exhaust brake
• Removal of auto start and stop as well as idle timers
• Tire sized changed and if opted for transmission calibration it is optimized for specific tire size / gear ratios

Transmission Calibration

• Extended transmission life, increased fuel economy, and better driving experience
• Increased line pressure and shift parameters that would reduce shift times, slip etc follow actual torque models in ECM and TCM
• This strategy increases fuel milage, reduces duty cycle wear, eliminates harsh or random inconsistent shifts or characteristics that do not match the drivers request, input or desired feel
• This is why it is important the engine calibration be done correct or our transmission calibrations be paired with our engine calibrations as the models have to mimic each other
• All calibrations match the increased torque as well as earlier torque to apply it most efficiently
• Refined shift points to get rid of the low rpm lazy feel at low driver inputs cruising or towing waiting on the turbo to spool that usually results in a lot of pedal travel and down shift
• Tire size, gearing, and larger turbos this is a must to tailor to that specific mod
• Earlier converter lock up to use increased torque & increase fuel milage as well as reduce temps
• Earlier unlock & downshift eliminates lag from time of driver input to acceleration
• Torque converter OEM partial lock or locked shifts to remove flare feel during shifts
• TC feel can be stock or increased for less slip to lock time in 2-6 gears
• Full manual control over shifts in driver select mode
  
• Since hydraulic pressure is directly related to your clutch holding power we do not recommend tuning over heavy tow without an aftermarket valve body
