Technical Information Looking After Your CVT
CVTs are safe with power levels from the Hondata reflash or FlashPro but power-braking will damage the CVT even at stock power levels.
Hondata tested their CVT calibration for over a year before releasing to the public. In addition, our daily driver Civic has done over 20,000 miles in the last 18 months problem free at power levels 20% higher than our CARB reflash. Part of the testing procedure involved running a CVT Civic for 6 hours on the Miller Motorsports raceway in Utah. After the race, we disassembled and examined the transmission. All parts were as new. Hondata is confident of the robustness and reliability of their calibrations.

Consequences of power brakingPower braking is depressing the throttle and brake simultaneously. This has the effect of transmitting the entire engines’s power output into the CVT drive belt and cones. The CVT drive cones will slip, score and over-heat the belt. Power braking will damage any transmission, with a reflashed or stock ECU.
Do not power brake.

Honda Australia has an optional OEM front mounted transmission oil cooler, as the Australian Civics can be configured for trailer towing. Consider fitting a larger front mounted oil cooler to your CVT. There are several aftermarket companies that sell CVT oil coolers.
