Emissions

Emissions Selection

Most 2008-2010 6.4L Powerstrokes are equipped with an emissions system designed to run Ultra Low Sulfur Diesel (ULSD) Fuel. If you have removed or modified this emissions system (or plan to immediately after installing this device), proper tuning must be installed or the vehicle will not operate correctly. Select REMOVED at this option for a modified emissions system and high sulfur fuel use. Select PRESENT if your emissions system requires ULSD fuel.
Exhaust Emissions Equipment

When running ULSD tuning, it is required that all sensors located in the exhaust system stay in place and plugged in, otherwise you may experience a Check Engine Light (CEL) and even a loss of power (limp mode).

When running High Sulfur tuning, it is recommended that all sensors located in the factory exhaust system be unplugged from the electrical harnesses. These sensors can also be removed completely with the factory exhaust if desired. On the 6.4L Powerstroke, there are usually 3 EGT Sensors and 1 Pressure Sensor.

Note: The vehicle will not run with sensors
removed unless High Sulfur tuning is installed.

EGR Emissions Equipment

When running H&S High Sulfur tuning, it is not required to unplug or block-off the EGR system on your 6.4L Powerstroke to disable it. The EGR system is already disabled in the tuning and will not function under any conditions. If desired, the entire EGR system can be unplugged, blocked-off, or completely removed when running H&S High Sulfur tuning.

Transmission Tuning
Transmission Reset / Relearn
The 5R110 automatic transmission on the 2008 – 2010 6.4L Powerstroke has what is called Adaptive Memory and is constantly learning and adapting to different horsepower levels, temperatures, driving habits, etc. After completing the Install Download process on the 6.4L Powerstroke, the Transmission Adaptive Memory is automatically reset. We highly recommend performing a Transmission Relearn procedure after installing H&S tuning to help the transmission perform correctly with the added horsepower. The 5R110 automatic transmission will eventually learn over time on its own, but the relearn procedure gives a good baseline for the adaptive learning and helps to speed up the learning process. To perform the relearn procedure, please follow these instructions: When re-training the transmission, ALWAYS follow posted speed limits. Do NOT attempt runs in adverse weather conditions such as snow, ice, rain, wind, or any other conditions that may affect your vehicles traction or impair your visibility!
  1. After H&S tuning is installed, perform each of the following 0-80 MPH runs while in the HOT power level. During this relearn process, you may experience hesitation during shifts, hard shifts, or defuel patterns, all of which are normal:
  • 0-80 MPH @ 25% throttle position, then slow down and come to a complete stop.
  • 0-80 MPH @ 50% throttle position, then slow down and come to a complete stop.
  • 0-80 MPH @ 100% throttle position, then slow down and come to a complete stop.

The Transmission Relearn procedure is complete.

Note: On any vehicle using 3″ or larger lift blocks under the rear leaf pack, it is HIGHLY RECOMMENDED to install traction bars. With any added horsepower, failure to do so may result in harsh shifting and may cause premature transmission and/or driveline damage.

Other Features

Low Boost Fueling

This option allows for adjustment of the amount of fuel injected under low boost conditions. There are 5 different settings for Low Boost Fueling:

  • 0 – Lowest Fueling
  • 1 – Low Fueling
  • 2 – Medium Fueling (Default)
  • 3 – Moderate Fueling
  • 4 – High Fueling
Note: The low boost fueling adjustment will affect ALL power levels. This option can only be adjusted during the Install Download process.

TPMS Adjustability / Disable

Many 2008 – 2010 6.4L Powerstrokes are equipped with a TPMS or Tire Pressure Monitoring System from the factory. This system is designed to alert the driver of a problem with the vehicles tire pressures but is often a nagging inconvenience for those individuals wanting to run lower pressures or get rid of the TPMS sensors altogether. H&S Performance has a designed solution for those individuals. By using your H&S tuning device and a 6.4L Powerstroke TPMS Adapter (Part #709913), you will have full control of the TPMS. Front and rear tire pressures will be independently adjustable from 0 – 100 PSI as well as the option to Disable the TPMS completely if removing the TPMS sensors from the vehicle. All changes to the TPMS must be done with the 6.4L Powerstroke TPMS Adapter in place and the Adapter must be removed after changes are made to resume normal tuner function.
