If you had a choice between the Takegawa 181cc Hyper S-Stage with FI CON 2 or Yuminashi 164 ultimate w/ new version standalone ecu which would it be? I ordered a yuminashi but I'm having seconds thoughts. Anyone have any experience w/ the new ecu w/ datalogger? Can you use The WBC2 from hard racing w/ the yuminashi ecu? I'm interested in hearing other people opinions and experiences. I haven't been able to find any reviews on the new yuminashi ecu and how user friendly it's is, as I don't have any experience in tuning.
