Whats the difference between the reflash and the K-Pro?
The reflash consists of a one-time changing of the stock ECU programming. You send in your ECU, immobilizer and key, and Hondata will program the ECU and send it back to you. The K-Pro system lets you program the ECU yourself after Hondata has added a daughterboard and a USB connector to your ECU. You can then connect a computer to the ECU, run the Hondata K-Pro ECU Manager software and either load one of the several “calibrations” Hondata ships with the software (many run well without the need for further tuning), or have a tuner create a custom calibration for your car.
