Honda and Acura ship these cars 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 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\u003cp\u003eThe same Accessport V3 hardware covers the FK8 Civic Type R, the FL5 Civic Type R, and the DE5 Integra Type S. What changes between them is the calibration, the available map stages, the emissions approvals, and how the ECU gets unlocked for flashing. Select your chassis above, and read your car's section below for the details that apply to you.\u003c\/p\u003e\n\n\u003ch4\u003eCOBB Custom Features\u003c\/h4\u003e\n\n\u003cp\u003eBeyond the maps, the Accessport unlocks a set of performance features the factory ECU doesn't give you, on all three platforms:\u003c\/p\u003e\n\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eLaunch Control:\u003c\/strong\u003e holds a set launch RPM when you're flat on the throttle, so you can drop the clutch for a consistent, repeatable launch instead of feathering it every time.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFlat Foot Shifting:\u003c\/strong\u003e lets you keep the throttle pinned through upshifts (no-lift-to-shift), which keeps the turbo spooled and boost up so you don't lose momentum between gears.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBurnout Mode:\u003c\/strong\u003e lets you spin the front tires to clean or warm them up before a run.\u003c\/li\u003e\n\u003c\/ul\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\u003chr\u003e\n\n\u003ch3\u003eFK8 Civic Type R (2017-2021)\u003c\/h3\u003e\n\n\u003cp\u003eThe FK8's K20C1 turbo motor responds hard to a tune. Boost, timing, and fuel are all conservative from the factory, and the 2.0T has the headroom to make real gains on the stock airbox and intercooler. You're not chasing a few peak horsepower here; you're fattening up the entire torque curve, which is what makes the car quicker in the real world rather than just on a dyno sheet.\u003c\/p\u003e\n\n\u003ch4\u003eReal Power Gains (Stage 1)\u003c\/h4\u003e\n\n\u003cp\u003eThese are COBB's measured Stage 1 numbers against the stock baseline, and the story is in the midrange. On the \u003cstrong\u003e91 octane\u003c\/strong\u003e map you're looking at a peak of about 315 hp and 357 ft-lb, with the biggest single-RPM gains landing around +20% in the midrange. Step up to the \u003cstrong\u003e93 octane\u003c\/strong\u003e map and it climbs to roughly 326 hp and 377 ft-lb peak, with midrange gains as high as +30% at a single RPM point.\u003c\/p\u003e\n\n\u003cp\u003eThe number that actually matters is the average across the whole rev range, because that's what you feel every time you get on it:\u003c\/p\u003e\n\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003e91 octane:\u003c\/strong\u003e average torque goes from 267 to 285 ft-lb, average horsepower from 221 to 239 hp.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003e93 octane:\u003c\/strong\u003e average torque goes from 267 to 307 ft-lb, average horsepower from 221 to 255 hp.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eThat average torque jump of roughly 40 ft-lb on 93 is why a tuned FK8 feels like a different car in the midrange, where you actually drive it.\u003c\/p\u003e\n\n\u003cp\u003e\n    \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2218\/5701\/files\/Cobb-Accessport-V3.jpg?v=1793652158\" alt=\"COBB Accessport V3 Stage 1 dyno chart for the FK8 Honda Civic Type R, stock vs tuned\"\u003e\n\u003c\/p\u003e\n\n\u003ch4\u003eWhat Stage 1 Needs (FK8)\u003c\/h4\u003e\n\n\u003cp\u003eStage 1 is designed to run on the stock airbox, filter, and intercooler, so you don't need to buy anything else to use it. A replacement air filter in the factory airbox and exhaust components that retain the factory catalytic converters are both safe to run with the OTS maps, and a stock or upgraded catback works fine. It targets about 25 psi of boost, tapering as the engine approaches redline.

Like the FK8, these cars leave a lot on the table from the factory, and COBB's maps reclaim it with more boost and more aggressive timing and fueling for a real gain in both low-end torque and top-end power.\u003c\/p\u003e\n\n\u003ch4\u003eA Longer Staged Path\u003c\/h4\u003e\n\n\u003cp\u003eWhere the FK8 runs a Stage 0 \/ Stage 1 path, the FL5 and DE5 get a fuller ladder of COBB performance maps: \u003cstrong\u003eStage 1, Stage 1+, and Stage 2\u003c\/strong\u003e, each one more aggressive than the last. As with every platform, Stage 0 keeps the full factory calibration and makes no extra power; it just unlocks the Accessport's monitoring and datalogging functions on a stock tune. The OTS maps are built for otherwise-stock cars, so a replacement air filter in the factory airbox and exhaust that retains the factory catalytic converters are safe to run on them. The higher up the ladder you go, the more the map expects supporting hardware and the right fuel, so check COBB's map notes for the exact fuel grade and parts each stage calls for before you flash it.\u003c\/p\u003e\n\n\u003ch4\u003eDyno Results (FL5\/DE5)\u003c\/h4\u003e\n\n\u003cp\u003eStock versus tuned on the FL5 and DE5, showing the gains COBB's calibration pulls out of the K20C1:\u003c\/p\u003e\n\n\u003cp\u003e\n    \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2218\/5701\/files\/Screenshot_2-11-2026_143515_www.cobbtuning.com.jpg?v=1793651811\" alt=\"COBB Accessport dyno chart for the FL5 Honda Civic Type R and DE5 Acura Integra Type S, stock vs tuned\"\u003e\n\u003c\/p\u003e\n\n\u003cp\u003eStage 1 + SF results:\u003c\/p\u003e\n\n\u003cp\u003e\n    \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2218\/5701\/files\/Screenshot_2-11-2026_143529_www.cobbtuning.com.jpg?v=1793651811\" alt=\"COBB Accessport Stage 1 + SF dyno chart for the FL5 Civic Type R and DE5 Integra Type S\"\u003e\n\u003c\/p\u003e\n\n\u003cp\u003eStage 2 results:\u003c\/p\u003e\n\n\u003cp\u003e\n    \u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/2218\/5701\/files\/Screenshot_2-11-2026_143540_www.cobbtuning.com.jpg?v=1793651811\" alt=\"COBB Accessport Stage 2 dyno chart for the FL5 Civic Type R and DE5 Integra Type S\"\u003e\n\u003c\/p\u003e\n\n\u003ch4\u003eRead This First: ECU Must Be Shipped to COBB to Unlock\u003c\/h4\u003e\n\n\u003cp\u003eThis is the big difference from the FK8, and you need to know it before you buy. On the FL5 and DE5, the Accessport can't communicate with the ECU until the ECU has been unlocked, and that unlock is not done in the car. You remove your ECU and ship it to COBB Tuning, they unlock it, and you reinstall it. That means real downtime with the car off the road while the ECU is out, and it's a step you have to plan around rather than a 6-minute driveway flash like the FK8. Once your unlocked ECU is back in the car, flashing and map-switching work from the handheld like normal.
