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.

1. 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.
2. 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).
