2013 Honda Civic Si Stage 1 With Idle and Misfire Fix for Lightweight Flywheel RX0-A140

When performing a single mass flywheel/lightweight conversion on these cars, they may experience a false misfire due to changes in harmonics, triggering the ECU to activate limp mode. This tuning solution effectively resolves this issue, ensuring smooth operation with the lightweight flywheel. The tune is optimized for 91 octane fuel, with VTEC/cam angle adjustments to enhance midrange torque. Additionally, emissions controls are disabled for off-road racecar applications, and the speed limit is removed. Fuel enrichment is set to 13.0:1, tapering to 12.6 by redline for optimal performance.
