Take your 11th Gen Si to the next level with our all NEW TSP Stage 1 Tune!

Two Step Performance has partnered with Derek Robinson to offer a high quality tune for the 2022+ Civic Si that offers an additional 45 whp and 96 ft lbs of torque in comparison to the factory ECU calibration. Full details are as follows:

196whp / 190tq - Factory Calibration
241whp / 286tq - TSP Stage 1 Tune

*Designed with the stock clutch in mind, with a soft ramp in torque; we recommend a 1,000+ mile soft break-in period on the stock clutch before flashing this calibration.

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 1: Factory boost levels and turbocharger response.
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.

*Tune orders placed during business hours are typically fulfilled via email the same day. Orders outside of business hours are filled the following business day. FlashPro tune orders may be slightly delayed due to the process required to build your custom file.* Hondata FlashPro users should also note that we are NOT offering a secondary O2 disable service for this tune, which means you are not able to use this tune with a downpipe that does not meet emission standards. 

Please verify that your ECU is supported via our TSP Tune Compatibility List prior to purchase.

This tune is for the 2022+ Civic Si only. Please be sure you are purchasing the correct tune for your vehicle because digitally delivered items are non-refundable. (For example, If you buy this for your 2016 Civic LX, it won't work, and we cannot offer a refund.)
