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 - 2013 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 down-
load 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.
•
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 when adding additional horsepower.
Keyed ignition source location
Although it is possible to manually power up the Mini Maxx without using a keyed ignition
source, it can sometimes create communication issues between the Mini Maxx and the
vehicles ECM. To eliminate these problems, we highly recommend tapping into a 12V keyed
ignition source to supply power to the Mini Maxx only when the key is in the ON position
