NMCA Tech Committee clarifies Chevrolet Performance Stock-approved controller and calibration

The NMCA Tech Committee, working with the teams from Scoggin-Dickey Parts Center and Chevrolet Performance, have completed a major overhaul of the CP Stock Rules for the 2021 season. The one remaining item that the Committee has been working on is refining the calibration. Unfortunately, there is not enough time before the start of the 2021 season for the Chevrolet engineers to complete the modifications to the calibration, implement those changes, and develop an effective distribution of a new ECU part numbers with the new calibration.

For the start of the 2021 season, the existing ECU in the rule set (Part numbers 19353299 or 19354341) are the only permitted controllers/calibration for the class.

Chevrolet engineers and the NMCA Tech Committee will continue the work on developing a new tune and will implement that at the appropriate time.
