Expanded RPM

Normal Honda ECUs fuel and ignition tables are mapped to 9,000 rpm.  You can safely rev the engine past 9,000 rpm, but the fuel and ignition values are fixed the same as at 9,000 rpm.  With the s200 system the fuel and ignition tables are mapped to 11,000 rpm on the high speed cam.  This allows you to tune engines correctly which run over 9,000 rpm.
