Cobb 17-20 Honda Civic SI (FC1/FC3) AccessPORT V3

The Cobb AccessPORT V3 is a handheld device that reprograms your ECU via OBDII for increased horsepower and torque on 2017-2020 Honda Civic Si models (FC1/FC3 chassis, 1.5L turbo 6MT). It delivers preloaded Off-The-Shelf (OTS) maps for immediate gains up to 25 whp and 50 ft-lb tq, plus advanced data logging to monitor boost, AFR, and more. Perfect for enthusiasts seeking straightforward performance upgrades without voiding emissions compliance.

Key Features

  • ECU Reprogramming: Flash proven OTS maps tailored for 91-93 octane fuel, yielding dyno-tested power increases while maintaining drivability and safety margins.
  • Data Logging & Monitoring: Log over 3,000 parameters including boost-by-gear control, throttle position, and knock feedback on a high-contrast 2.7-inch touchscreen.
  • Custom Tuning Ready: Supports Accesstuner Pro software for professional tunes, including flex-fuel and ethanol content monitoring for advanced setups.
  • User-Friendly Interface: Simple plug-and-play OBDII connection with automatic ECU recovery and valet mode for security.
  • Compact Design: Rugged, mountable unit (4.9 x 2.7 x 1.0 inches) with microSD slot for map storage and updates via Windows PC or Mac.

Product Notes

  • Requires 91+ octane for OTS maps; lower octane reduces power output.

  • Free lifetime map updates from Cobb server; USB cable and OBDII harness included.

Installation Notes

  • Professional installation recommended.
  • OBDII plug-and-play in under 10 minutes; no mechanical disassembly needed.
