Hondata modifies standard Honda engine computers (ECUs), adding features and expanding the capabilities of the ECU (e.g. for forced induction). These modifications are available either as a reflash, or a fully tunable system. Reflashes involve the ECU being sent to Hondata; programmable system require the ECU to be modified for pre 2006 vehicles or an external programming interface for 2006 and later vehicles. System’s we carry and tune are S300, Flashpro and Kpro.
