After months of careful research and development we have now released our Stage 1 tune for the 11th gen Si. All testing was completed on a stock 2022 Civic Si running 93 octane fuel. Tune features include:
- Numerous fuel, ignition, turbo response, throttle response changes.
- 3,000rpm standing launch limiter (adjustable via steering wheel)
- "Rev hang" softened
- On-the-fly boost map switching active
Map 2: 18psi normal, 20psi Sport mode, improved turbocharger response
Map 3: 25psi peak in normal/Sport modes, fastest turbocharger response
Factory boost level in "Map 1" allows for easy "valet" mode when the KTuner unit is unplugged from the car!
93 octane recommended. Use of lower grade fuel (91oct) will operate without harm, but gains will be smaller.
The calibration will support up to about 15% ethanol content if necessary to increase knock resistance.
Suitable for use with the factory intake or a QUALITY aftermarket intake that keeps fuel trims in check such as the PRL Motorsports High Volume Intake System. Aftermarket downpipes are also fine. Mods such as this are expected to add power that is not accounted for in our dyno testing.
In addition to standard sized intakes, the PRL Cobra Race MAF intake is supported. This MAF is *not* a direct bolt on part for the 11th gen, retrofit is required. Please select the appropriate option for your intake when ordering. Need to make a change later down the road? Take advantage of our File Conversion Service.
