Manual Regeneration
Manual regeneration allows you to manually clear out the Diesel Particulate
Filter (PDF). Completing a manual regeneration cycle will clear the soot mass
in the filter, and lower exhaust backpressure to improve exhaust flow. The
engine must be at operating temperature.
1 – Park the vehicle outdoors and keep people, other vehicles, and
combustible materials away from it.
2 – Do not leave the vehicle unattended.
3 – Do not connect any shop exhaust hoses or vents to the tail pipe.
STEP 1 – Access the Programming Menu.
STEP 2 – Using the +RES or -SET, select mode 50 (MPH)
STEP 3 – The speedometer will sweep to 140 and then back down to 0. When
the speedometer goes back to 0, you may then start the engine.
STEP 4 – A few seconds after starting the truck, if all conditions are
met, the regen will start. When regen is active, RPMs will increase up to 2500
RPM. If conditions are not met, the speedometer will sweep to 100 MPH for
approximately 10 seconds and the Manual Regen will be canceled automatically.
a. Vehicle must be to normal operating temperature for Manual Regen to
initiate.
STEP 5 – When the Manual Regen is complete or after the 10 seconds at 100
MPH, the speedometer will sweep to 140 MPH, indicating the function is
complete.
CAUTION
Exhaust temperatures may be greater than 300° C (572° F) during service
regeneration.
CAUTION
Due to the elevated temperatures during this procedure, open the hood and keep
the front of the vehicle away from anything impeding the radiator.
Manual Regeneration Cont’d
PDF REGENERATION
– If you own a newer diesel-powered vehicle, your vehicle is equipped with
a Diesel Particulate Filter (PDF). This filter is used in conjunction with a
diesel oxidation catalyst. Together they work to reduce the amount of soot and
emissions emitted from the tailpipe. As soot builds up in the PDF it will
begin restricting flow. The soot that gathers is automatically purged in one
of two ways: Passive Regeneration & Active Regeneration. Both methods occur
automatically and require no action on your part. During either of these
regeneration methods, you may notice an increase or change in the exhaust
noise & increased Exhaust Gas Temperature (EGT).
Transmission Relearn
This vehicle is equipped with a transmission that will “learn” while you
drive. Sometimes when these vehicles are programmed with an aggressive tune,
the transmissions act differently. This feature forces the transmission to
relearn and accommodate the new tune.
STEP 1 – Access the Programming Menu.
STEP 2 – Using the +RES or -SET, select mode 60 (MPH)
STEP 3 – The speedometer will sweep to 140 MPH, indicating the function
is complete.
Transmission Relearn driving instructions:
By selecting a Trans Relearn, you erase all shift points your transmission has
learned up to that point, so it is recommended that you follow the procedure
below.
- Start the relearn by making at least six sets of light throttle upshifts through all the gears, then make another six sets at 1/3, 1/2 and 3/4 throttle. Downshift the same way by starting at light throttle and working up to full throttle.
- Once the shifts are quick and smooth, press the
tow haul’ button and repeat the above step intow haul’ mode. Relearn normally takes up to two hours, but it can take up to 500 miles for the transmission to learn different upshifting and downshifting scenarios.
NOTE: After the relearn commands are sent there might be some clunks, bumps, and/or short flares, especially during the shift from third to fourth gear. This is normal.
Responsiveness Level Adjustment
When the vehicle is running and cruise control is turned off, the vehicle’s
throttle responsiveness can be adjusted. The responsiveness level is indicated
using the vehicle’s speedometer.
STEP 1 – Using the +RES or -SET, adjust to the desired value. The levels
changing will be shown on the speedometer, from 10 MPH to 50 MPH.
Level 0 = Stock
Level 1 = Reduced responsiveness (up to 15% less than stock)
Level 2 = Increased responsiveness (up to 15% over stock)
Level 3 = Increased responsiveness (up to 30% over stock)
Level 4 = Increased responsiveness (up to 48% over stock)
Level 5 = Increased responsiveness (up to 65% over stock)
STEP 2 – To recall the vehicle’s performance level, press the cancel
cruise control button.

FAQs
Frequently Asked Questions
Question: Can I adjust power levels when cruise control is on? Answer: No,
only when cruise control is off.
NOTE: Cruise control can be used as normal, you just can’t change power
levels when cruise control is on.
Question: Should I remove the Pulsar LT prior to going to the dealer?
Answer: Yes, please remove the Pulsar LT to eliminate it from the system
so they can perform any updates or services.
Question: How do I check what level I am on when cruise control is off?
Answer: Simply press Cancel on the power steering keypad.
Question: Can I “stack” or use other tuners with this device?
Answer: No, please do not use any other tuners when the Pulsar LT is in
use or installed. Stacking tuners with the Pulsar LT may cause serious damage
to the vehicle.
Question: What is the best way to accurately measure tire size?
Answer: Mark a line on the ground where the center of the tire rests,
then drive the vehicle for two full rotations of the tire and mark the spot
where it comes to a rest with another line. Measure the length between the two
lines and divide by two. Then divide that number by Pi (3.14159265359).
