A Hondata fuel system is required to achieve higher power levels. These CANFlex calibrations are conservatively tuned for your daily driver with 400 lb/ft torque and 400 hp. The CANFlex calibrations add about 70 HP and spool the turbo 200-400rpm earlier with E85. The red circled Delta is the power gain.

All Civic Type R and Integra-S ECUs require jailbreaking before they can have the CANFlex calibration installed. FL5 and DE5 ECUs require the ECUs to be jailbroken by Hondata or authorised dealer. All CANFlex calibrations can be tuned by an experienced tuner for more power and torque with a built engine.

Integra-S DE5

Your stock FL5 Civic Type R or DE5 Integra with CANFlex spools much earlier and delivers 28 more hp. Your Type R is so much more responsive and fun to drive. You can drive on anything from pump gas to E85. More power is available on a blend of E40-E50. (not tested here)
