What sort of improvements can I expect?

The tune is designed to give a conservative yet exhilarating 10% improvement in performance. With this Hondata performance upgrade, your Accord will match the performance of many more expensive luxury cars. Your Accord gains anywhere from 10 to 40 hp everywhere, with the maximum gains not at the top of the rev range, but where you need it most at the low end of the rev range. Rapid acceleration is just a quick flex of the throttle pedal away. 91 or higher octane recommended.

Accord MT 2.0 Flex Fuel

Flex fuel kits are now available for the Accord from retailers like ProCivic. In combination with FlashPro Manager or later the Accord becomes a fully flex fuel compatible vehicle. These tunes were developed on a completely stock MT and AT Accord. The Accord Flex-Fuel calibration will automatically adjust the tuning and boost levels to maximize the performance based on your ethanol content.
