If any special feature is already listed as Enabled but is not functioning correctly, you may need to disable
the feature, cycle the key, and re-enable the feature to make it function properly. If it still does not work, your vehicle
may not be equipped with the hardware required for the special feature. The previous selection will NOT be saved.
If the Special Functions/Features Menu is exited and returned into, it will not display your previous selection. This is
normal and the Enable/Disable function is still working properly.
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 sup-
ply power to the Mini Maxx only when the key is in the ON position and the vehicles ECM is online.
Below you will find a commonly used 12V keyed ignition source for your vehicle:
fUse nUMBer 30
Always tap into the
cold
side of the fuse. On the
2007.5 - 2009 6.7L Cummins, the
cold
side is towards
the drivers side of the vehicle.
noTe:
If your fuse box or wiring looks different than those pictured
or if you are not getting 12V ignition power from the pictured source,
you may need to find another 12V keyed ignition source using a test
light or multimeter. If possible, find one that stays
hot
during engine cranking.
overdrive Transmission software
Did you know that your H&S tuning device also has the capability of tuning your transmission? If
your 6.7L Cummins is equipped with the 68RFE automatic transmission, you may want to check
out our Overdrive Transmission Software. Custom tailored to mate with H&S engine tuning, the
6.7L Overdrive software includes boosted line pressures, modified full and part throttle torque
converter lock/unlock strategies, adjusted full and part throttle shift points, adjusted full and part
throttle shift firmness, modified torque management tables, and much more! 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 addition of the
H&S Overdrive tuning!
