With your H&S tuning device, you have full control of the TPMS. Front and rear tire pressures
are independently adjustable from 0-120 PSI as well as the option to disable the TPMS com-
pletely if removing the TPMS sensors from the vehicle. This option only takes a few seconds
to change and can be adjusted at any time from the Tire Pressure Calibration menu.
noTe:
TPMS adjustments will not take full effect on a stationary vehicle. Once adjustments have been made, it can
take up to 5 miles of driving before changes take effect.
Transmission Tuning
Did you know that your H&S tuning device also has the capability of tuning your transmis-
sion? Our transmission tuning for the 6R140 automatic transmission is custom tailored to
mate with H&S engine tuning. Some features include: boosted line pressures, modified full
and part throttle lock/unlock strategies, adjusted full and part throttle shift points, adjusted
full and part throttle shift firmness, and modified torque management tables. All changes
are designed to keep more power directed to the road instead of wasted in heat and friction.
On our test trucks, we have seen 0.2 to 0.3 second quicker 1/4 mile times JUST from the ad-
dition of H&S transmission tuning! An additional unlock fee may apply, see
www.hsperformance.com for details.
Transmission relearn
The 6R140 automatic transmission on the 2011 - 2014 6.7L Powerstroke has what is called
adaptive Memory
and is constantly learning and adapting to different horsepower levels,
temperatures, driving habits, etc. If you selected to tune the transmission during the Install
Download process, the Transmission Adaptive Memory is automatically reset when the
download completes. We highly recommend performing a Transmission Relearn procedure
after installing H&S transmission tuning to help the transmission perform correctly with the
added horsepower. The 6R140 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 at-
tempt 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
Performance
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.
