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 aect 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.
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
and the vehicles ECM is online. Below you will nd a commonly used 12V keyed ignition
source for your vehicle:
SOLID PURPLE WIRE
The SOLID PURPLE wire (capped from the factory) is found under the drivers side dash. This
SOLID PURPLE wire is bundled with multiple other capped wires near the OBD-II port.
NOTE: If your fuse box or wiring looks dierent than those pictured
or if you are not getting 12V ignition power from the pictured
source, you may need to nd another 12V keyed ignition source us-
ing a test light or multimeter. If possible, nd one that stays “hot”
during engine cranking.
