Honda ships the 1.5T with a conservative factory tune built to run on bad gas, pass emissions anywhere, and protect itself in any climate, which leaves meaningful power and a lot of midrange torque sitting on the table. The Accessport reflashes your factory ECU through the OBDII port with COBB's calibration, reclaiming that power while keeping the car safe and streetable. It's a handheld unit with a large full-color screen that mounts in the cabin, so it's both the tool you flash with and a live gauge display you leave in the car day to day. It's the world's best-selling ECU upgrade for a reason: it does the hard part for you.\u003c\/p\u003e\n\n\u003ch4\u003eIn-Cabin Monitoring and Customization\u003c\/h4\u003e\n\n\u003cp\u003eMounted in the cabin, the V3's large full-color high-resolution screen monitors up to six engine parameters in real time, so you can keep an eye on boost, intake temps, AFR, and the rest without hanging a cluster of standalone gauges off your pillar. The display is fully customizable: you can set up separate gauge layouts for race, street, and dyno use, choose from multiple bezel colors, and swap between the two included interchangeable faceplates to match your interior. It comes with an in-vehicle mount with an on\/off switch and fits thousands of standard vehicle mounts, so you can position it wherever it reads best. Underneath, more processing power, memory, and storage mean faster flashing and room to save all your maps and logs.\u003c\/p\u003e\n\n\u003ch4\u003eOTS Maps and the Staged Path\u003c\/h4\u003e\n\n\u003cp\u003eThe Accessport comes preloaded with COBB's Off The Shelf (OTS) maps, generated by COBB's calibration team for otherwise-stock cars, and they're also available to download from COBB's site. Stage 0 keeps the full factory calibration, so it doesn't add power; it just unlocks the Accessport's monitoring and datalogging functions on a stock tune. The performance maps are where the Si wakes up, with more boost and more aggressive timing and fueling for a real gain in both low-end torque and top-end power. Bolt-on friendly parts like a replacement air filter in the factory airbox and exhaust that retains the factory catalytic converters are safe to run on the OTS maps, and if you go further down the road, the Accessport also supports full custom tuning.\u003c\/p\u003e\n\n\u003ch4\u003eDyno Results\u003c\/h4\u003e\n\n\u003cp\u003eStock versus tuned on the FE1 Civic Si, showing the gains COBB's calibration pulls out of the 1.5T across the rev range:\u003c\/p\u003e\n\n\u003cp\u003e\n    \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2218\/5701\/files\/Screenshot_3-11-2026_1433_www.cobbtuning.com.jpg?v=1793736243\" alt=\"COBB Accessport stock vs tuned dyno chart for the 2022-2024 Honda Civic Si (FE1)\"\u003e\n\u003c\/p\u003e\n\n\u003cp\u003ePower and torque on the 91 octane versus 93 octane maps:\u003c\/p\u003e\n\n\u003cp\u003e\n    \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2218\/5701\/files\/Screenshot_3-11-2026_14318_www.cobbtuning.com.jpg?v=1793736243\" alt=\"COBB Accessport 91 octane vs 93 octane horsepower and torque gains for the FE1 Honda Civic Si\"\u003e\n\u003c\/p\u003e\n\n\u003ch4\u003eSimple Install\u003c\/h4\u003e\n\n\u003cp\u003eInstallation is genuinely easy: plug the included OBDII cable into your Civic's OBDII port and follow the on-screen instructions.
