Hey guys.. im sure i have read about this before here on oz honda but could'nt find the thread for the love of me.... Anyways the main difference in performance between AUSDM and JDM DC2R's is how they are tuned right... Is that engine tuning/setup or computer tuning, As i have both a 2000 AUDM DC2R ecu and a JDM one.. they both run in my Brothers DC2R fine but does anyone actually know if the JDM ecu will give him more power?? which one should he run...
