Chevrolet Performance announces the launch of "100 Octane Fuel Calibration" for a 2015 or 2016 Z06 Corvette to the Chevrolet Performance Parts Program.
The 100 octane calibration is optimized for track use with 100 octane fuel. The calibration changes to improve performance with higher octane fuel have not affected emissions, and this calibration is 50‐State emissions legal with CARB Executive Order D‐126‐41. If used on the street with lower octane fuel, 93 octane rating or less, drivability issues may be experienced. In particular it is possible that detonation or spark knock may occur in hot climates or hot running conditions with fuel that has a lower octane rating than 100. Spark knock results in the ECM retarding spark timing which will/may result in reduced engine performance. We recommend using 100 octane fuel with this calibration to maintain peak engine performance.
Note to Dealers: To reprogram the "100 Octane Fuel Calibration" please call Techline Customer Support Center ﴾TCSC﴿ at 1‐800‐828‐6860 for programming requirements and instructions. Please be ready to provide the VIN prior to calling. TCSC will bill the Dealership directly for the calibration.
Warranty Information: Re‐flashing the vehicle with this calibration maintains the vehicle’s warranty.
