New Camaro ZL1 eLSD Drag Race Calibration Available

A new performance calibration is available from Chevrolet Performance for 2017-2019 Camaro ZL1 models (in Canada, 2019 Camaro ZL1 models only) that enhance launch capabilities on the drag strip. (Fig. 1) The calibration has been developed through continuous drag strip development of the Camaro ZL1 to enable enhanced performance right from the starting line.

The Electronic Limited Slip Differential (eLSD) Drag Race Calibration has been developed to enable more consistent burnout performance for improved drag strip launches. The calibration doubles the differential coupling torque during burnout and drag launch scenarios by increasing the pressure applied to the clutch pack in order to prevent relative slip between the clutch plates. As a result, burnouts warm both tires evenly, which is essential for a straight launch.


Camaro eLSD Calibration Update

The eLSD Drag Race Calibration requires reprogramming the Chassis Control Module. Before programming, contact the Techline Customer Support Center (TCSC) for programming requirements and a Vehicle Configuration Index (VCI). The VCI is valid only for the specific VIN provided by the technician.

To install the calibration, reprogram the Chassis Control Module using the Service Programming System (SPS). Module software and utility files are updated along with the calibration files. Clear any DTCs that set during reprogramming.

Refer to Chassis Control Module Control Calibration Data File Package Installation – GM Performance Drag ZL1 Instruction ID: 84612071 (Document ID 5135164 in the Camaro Accessory Installation Manual) for more information.

The updated calibration is for drag racing purposes on an appropriate track. It is only enabled when traction control and electronic stability control (ESC) are disabled. Drivers can turn off traction control and ESC by pressing and holding the traction control button for five seconds. Driving the vehicle on public roads with traction control and ESC disabled is not recommended.

Updating the Camaro ZL1 with the eLSD Drag Race Calibration from Chevrolet Performance maintains the vehicle’s warranty.

  2. Is this the same cal that was talked about in 1/9/2019 GCUS-9-7157?

  3. Can this also be done on the SS 1LE with ELSD?
