Hondata CAN 4 Port Boost Controller – 2012–2015 Honda Civic Si
Turbos and 9th Gens go together a little too well. If you want that power without sketchy boost spikes, the Hondata CAN 4 Port Boost Controller lets your ECU handle everything. This Civic Si CAN boost controller plugs right into your existing Hondata FlashPro setup for 2012–2015 cars, so you get smoother boost curves, faster spool, and power you can actually put down instead of random surge and creep.
On a turbo 9th Gen Civic Si, a 4 port solenoid Honda Civic setup is a big step up from the usual 3-port. You can run a softer wastegate spring for better traction and part-throttle drivability, but still command higher boost when you’re in it. The Hondata boost control kit Civic Si (SKU: HON-CANBOOST) includes the Hondata E/B/CAN adapter, CANBoost OBD2 cable Civic, boost control cable, and the Hondata 4 port boost controller. With Hondata FlashPro Manager V4.5.0.0+ and the built-in Hondata FlashPro boost control tables, your Civic Si electronic boost control happens entirely in software, no manual 2012–2015 Civic Si boost controller knob, no extra gauge cluttering the dash.

If you’re turbocharging a 2012–2015 Civic, this Hondata boost control kit Civic Si gives you stable, repeatable 9th Gen Civic Si boost control straight through the ECU. It’s a Hondata FlashPro boost kit built by Hondata and validated around their CAN-based strategy, and we still use this same Civic Si turbo boost controller on our own cars because it’s consistent, predictable, and easy to tune.
