Accessport Tuning for 2022-2024 FE1 Honda Civic Si
About this time last year, we were well into the development cycle of Accessport tuning for the Fk8 Civic Type R. Since releasing our first Honda Accessport in over a decade, we have also implemented some of our bespoke COBB Custom Features and added full tuning support for the FL5 Civic Type R & DE5 Integra Type S as well as the FC1/FC3 Honda Civic Si. The COBB Hard Parts Team is deep into development of some really cool parts for supported Hondas, more on that coming soon! Today, we are SUPER excited to expand supported vehicle coverage with the addition of a new Accessport, the AP3-HON-004, which covers Honda’s 2022-2024 Civic Si (FE1).
Vehicles Supported
The FE1 Civic Si is equipped with a 1.5L turbocharged variant of their L series motor that is ripe with potential. These little motors are capable of some serious efficiency, and with a bit of tweaking, a great deal of fun. The Accessport and COBB Off The Shelf maps are compatible with the following vehicles:
Accessport for Honda Civic Si (FE1) 2022-2024
Introducing the COBB Accessport for Honda USDM (FE1) 2022-2024 Civic Si. The Accessport is the world’s best selling, most flexible, and easiest to use ECU upgrade solution. Unlock power hidden within the vehicle by replacing conservative factory settings with more aggressive calibrations. Follow our staged upgrade path with pre-loaded Off The Shelf (OTS) maps or use custom mapping for any modification level. It’s the last engine management solution you’ll ever need. Tuning your Honda Civic Si has never been easier!
Off The Shelf Maps & Power Gains
Included with the Accessport are what we call Off The Shelf Maps. These performance calibrations are created to be used on an otherwise stock vehicle while running either 91 octane or 93 octane fuel. In stock form, the 1.5L motor has quite a bit left on the table. After adding in some boost, dialing in closed loop fueling, and optimizing timing in relation to observed charge air temperatures, our Calibration Team was able to add a respectable amount of power.
Included COBB OTS Maps
Stage0 v100
Stage1 91OCT v100
Stage1 93OCT v100
Below you can see our dyno graph and power gains chart comparing output of our Stage 1 91 and Stage 1 93 calibrations to the stock baseline. Where the stock car measured in at 201hp and 205tq at the wheels, our calibration team has been able to produce a very healthy 225hp and 251tq on 93 octane. Gains on 91 octane are only slightly less, coming in at 218hp and 245tq measured at the wheels. Full breakdown is below. Head over to our Map Notes Page for additional information about our Off The Shelf Maps including parts and fuel requirements, revision history, and more.
In the clear, no matter where you live
The COBB Accessport for the 2022-2024 Honda Civic Si (AP3-HON-004) allows you to flash and tune without worry as our device and all calibrations come with coverage via an executive order from CARB (D-660-226). This means you don’t need to duck and dodge the fuzz or even need to uninstall before going in for any smog checks. We’ve got you completely covered at full power, no secondary neutered calibration.
Only The Best!
With the AP3-HON-004 Accessport, you’ll have the fastest logging rate in the aftermarket Honda scene at up to 50hz depending on monitors and even the ability log an absolutely insane 50 monitors simultaneously. You can also live view up to six of those data points with digital gauges on the high-resolution screen!
Accesstuner Pro Custom Tuning
For those interested in custom tuning, our Accesstuner Pro software also now supports these vehicles. Any of our Authorized Honda Protuners can create a custom calibration for use with your Accessport. Find a COBB Honda Protuner HERE.
