KTuner Flash-based system for 2017-2021 Civic Si 1.5 Turbo. The KTuner Flash system allows you to reprogram/reflash your stock ECU directly over your OBD2 diagnostic port. No need to remove your ECU, etc. Simply plug the KTuner Flash system into your OBD2 port under your dash and reflash or tune your car using the KTuner software. Using the KTuner Flash system, you can retain all of your factory drivability, emissions, and reliability, while still being able to tune your engine for modifications (ie: intake, exhaust, boost increases, etc). The result will be a much better running engine with increased power!
What is included with the KTuner Flash system?
- KTuner hardware (part that plugs into your OBD2 port)
- USB cable (plugs into your laptop on one end, and into the KTuner hardware on the other end)
- Pair of KTuner window decals
- KTuner software (download for free here: http://ktuner.com/downloads/)

We are currently offering multiple research calibrations based on our 1.5T maps from the standard Civic with more to come in the future. All tunes should be run with 91+ octane for expected results.
Factory Starting Point:
Improved throttle response
Removed throttle dampening on low end, better performance off the line
Factory boost levels
Starter 19.5 PSI:
Improved throttle response
Removed throttle dampening on low end, better performance off the line
Reduced turbo lag
Improved low-end and midrange torque
Boost raised to 19.5psi after peak torque, whereas factory only targets 19 at the peak RPM of 5700 and then drops off again
Producing a much more sporty feel, better drivability, and additional top end power!
Starter 21.5PSI:
Improved throttle response
Removed throttle dampening on low end, better performance off the line
Reduced turbo lag with aggressive spool up
Improved low-end and midrange torque

Dyno Testing 23PSI Basemap:
Gains: 56wtq, 35-40whp midrange, 34whp peak to peak. There’s more left in the top end, but we’re staying conservative. Custom tuning can take it to the next level.
Dyno Testing 23PSI Basemap with Flex Fuel Kit (E35):
Gains: 75wtq, 60-65whp midrange, 65whp peak to peak.
