CORVETTE

This calibration is optimized for track use with 100-octane fuel. The calibration changes to optimize 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 may result in reduced engine performance. We recommend using 100-octane fuel with this calibration to maintain peak engine performance. This kit revises the engine calibration for 2015 and 2016 Z06 Corvette (automatic and manual) transmission to maintain performance during track use.
