Description

The Pulsar LT is a new in-line module for 2020-2022 Chevrolet Silverado 1500 and GMC Sierra 1500 3.0 L Diesel that offers complete adjustability of many features, all from your steering wheel controls. Without modifying your truck’s ECM, Pulsar LT offers you the ability to adjust throttle response, tire size, gear ratio, TPMS, and your top speed limiter. Pulsar LT can also be used to disable Auto Start/Stop, run a manual DPF regeneration cycle, transmission relearn and adjust your hi-idle function. It connects directly to the vehicle computer system, making installation a breeze and leaving your factory warranty intact.

Features:

• Toggle Auto Start/Stop
• Calibrate Tire Size (29″ – 50.9″)
• Adjust Throttle Response
• Modify Gear Ratio (2.00 – 6.99)
• Change Top Speed Limiter (82 – 124 MPH)
• Clear Diagnostic Trouble Codes
• Reprogram TPMS Threshold (1 – 99 PSI)
• Manual Regeneration
• Transmission Relearn
• Adjust High Idle (700-1500rpms)
• Simple Installation Process
• Does Not Modify ECM
• Leaves Factory Warranty Intact

Notes:

This works in the 2022 classic model only, it is not compatible with the 2022-2023 Refresh models

When physically changing ring and pinion gears in the late model GM trucks, the factory cruise control will be disabled. While the Pulsar will allow you to recalibrate the speedometer for that gear change, it will not re-activate the disabled cruise control system or correct any codes that are set. GM has this feature laced into the calibration files and would require full ECM/TCM tuning to re-enable cruise control or to correct any other codes or drivability concerns
