Installation

Materials

Required Tools

Plastic Pushpin Puller / Flat Head Screwdriver
T-15 Torx Bit

Device Installation

1. Before installation, to prevent codes or other issues, disconnect the negative battery terminal connector from BOTH batteries.
2. Remove driver's side inner fender to gain access to the stock connector. Using a T-15 Torx bit and a Flathead Screwdriver, remove all the retainer screws and pushpins and remove the inner fender well. For easier installation, you can remove the driver's side wheel, but this is not necessary.
3. Locate and disconnect the stock connector (see Pic A for stock connector location). Release red locking tab by pushing the red tab up as shown. Press the bottom right tab on the connector inward to release. Then the connector can slide upwards toward the red tab to take it apart as shown.
   NOTE: The Pulsar LT connector can plug into two locations in the fender well, so make sure you are connected to the one shown in Pic A.
   
4. Connect the Pulsar to the stock connector in the reverse order.
5. Route the Pulsar LT harness up towards the engine bay. With the Pulsar LT module disconnected, feed the Pulsar LT harness between the coolant reservoir and the brake booster as shown.
   
6. Using the supplied 10-inch zip tie, secure the free connector to the lower as shown below.
   
7. Clean the top of the fuse box lid, then mount the Pulsar LT to the fuse box using the supplied Velcro strips.
   
8. Reinstall the fender liner.
9. Reconnect batteries.

Speed Limiter

Removal / adjustment of the factory speed limiter is intended for use in a close-circuit, legally sanctioned racing environment. If you drive on public roads after removal or adjustment of the speed limiter, you must still obey all driving laws, including adhering to posted speed limits. To drive at racing speeds on public roads seriously endangers you, passengers, and others nearby. It is also your responsibility to ensure your tires and other vehicle components are rated to travel at increased speeds. Driving at high speeds with inadequate tires or other components can lead to serious or fatal injury.

1. Access the Programming Menu.
2. Using +RES or -SET, select mode 10 (MPH).
3. Press cancel cruise to select.
4. Speedometer sweeps to 140 MPH for 3 seconds indicating Speed Limiter has been selected.
5. Use +RES or -SET wheel to adjust to the desired value.
6. Press the cancel cruise control button to save the input value.
7. The speedometer will sweep to 140 MPH indicating the function is complete.

Removing / adjusting the speed limiter for purposes inconsistent with the products's intended function violates the product's intended use and will invalidate the product's warranty. Powerteq is not responsible for or liable for the consequences of improper product use.

Manual Regeneration

Manual regeneration allows you to manually clear out the Diesel Particulate Filter (DPF). Completing a manual regeneration cycle will clear the soot mass in the filter, and lower exhaust back pressure to improve exhaust flow. The engine must be at operating temperature.

NOTE: When manually initiating a regeneration cycle, some vehicles will require a drive cycle (i.e you have to drive the vehicle some distance) while others may allow you to initiate Service Regeneration where you can leave the vehicle parked and the engine running. If the latter is the case, be sure to use the following guidelines.

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.

Procedure

1. Access the Programming Menu.
2. Using the +RES or -SET, select mode 60 (MPH)
3. The speedometer will sweep to 140 then back down to 0. When the speedometer goes back to 0 you may then start the engine.
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.
   NOTE: Vehicle must be to normal operating temperature for Manual Regen to initiate.
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.

Exhaust temperatures may be greater than 300C (572 F) during service regeneration.

Due to the elevated temperatures during this procedure, open the hood and keep the front of the vehicle away from anything impeding the radiator.

DPF REGENERATION - If you own a newer diesel powered vehicle, your vehicle is equipped with a Diesel Particulate Filter (DPF). 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 DPF 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.

1. Access the Programming Menu.
2. Using the +RES or -SET, select mode 70 (MPH)
3. The speedometer will sweep to 140 MPH, indicating the function is complete.

NOTE: After the relearn commands are sent there might be some clunks, bumps, and/or short flares. This is normal. Completion of this feature will require a minimum of 3 upshifts at a steady throttle angle.

Update Software

Downloading Update Agent 1.0

(Optional)
The Update Agent may be used to update the device via the USB connection. The software can be downloaded through the internet. This process currently can only be done on a Windows computer, Mac devices are not supported.

Product Updates

(Optional)
This device has the ability to update via a USB connection. A USB to OBDII update cable is required to perform the update. The cable is sold separately. It is recommended that a battery charger is attached and turned on during the update process.

NOTE: The Pulsar must be installed into a vehicle before updating. When updating, you CANNOT use your vehicles Wi-Fi. It will be disabled during the update process. Use an external source such as your home Wi-Fi.

1. Take computer with Update Agent 1.0 installed to the location of the vehicle with the Pulsar device.
2. Turn the vehicle's ignition to the RUN position (do not start the engine) and then open Update Agent 1.0 on the computer, and plug in USB to OBDII cable into both the vehicle's OBDII port and a USB port on the computer.
3. Update Agent 1.0 should automatically detect the Pulsar device, follow onscreen instructions until it checks for an update. If an update is available, click yes.
   NOTE: If you have not yet registered for an account and/or signed in, you will be prompted to do so before you can proceed with the update.
4. Follow update steps as shown onscreen. Do not power down the vehicle during the entire process unless prompted by the Update Agent. Once Update Agent 1.0 says "Your device is up-to-date," click ok and disconnect the USB to OBDII cable.
   

NOTE: OBDII Port location may vary depending on vehicle

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 prior to going to the dealer?
Answer: Yes, please remove the Pulsar as 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 steering wheel cruise control buttons.

Question: Can I "stack" or use other tuners with this device?
Answer: No, please do not use any other tuners when the Pulsar is in use or installed. Stacking tuners with the Pulsar 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 π (3.14159265359).
