Reflash Service

The Hondata mail-order reflash service is designed for the 2002-2005 Honda Civic Si (EP3) with the PNF engine computer. This service optimizes your vehicle's fuel, ignition timing, and cam timing for improved performance. The rev limiter is raised to 7700rpm, and power gains of 10-12 peak horsepower are expected, with an improvement of 4-9 ft-lb of torque across the rev range. The power peak is raised by 400 rpm, from 6300 rpm to 6700 rpm (or higher with headers), and 0-60 mph times can be improved by up to one second. This reflash is fully compatible with all Honda scan tools and equipment. The service requires you to ship your ECU, immobilizer, and ignition key to Hondata for the reflash to be completed, after which it will be shipped back to you. It is recommended to use 91 octane fuel with this reflash. This product is for OFF-ROAD MOTORSPORT/COMPETITION RACING USE ONLY and is never to be used on any pollution-controlled motor vehicle.
