ECU must be sent to Hondata in order to be re-flashed with the updated program. Hondata does not sell direct - all sales and payment must be conducted through Hondata dealers. The upgrade information form must be sent with your ECU.

curious/stupid question: what makes the K20z2 different from the K20z3? can it be easily changed?
