* Currently in testing

Feature Rich

Unlock all of the best features that you demand in stand-alone ECUs -- without breaking the bank

Frequent Updates

Our active community of developers makes HTS the comprehensive tuning suite you need for your Honda

Our Mission

Our goal is to support OBD0, OBD1, and K/R/L/J series (with flashing) —  something that no other free software has accomplished.

Honda Tuning Suite, while still in development, is fairly featured and operational for the average tuner. Along with the tuning functionality basics, HTS ships with so much more including real-time datalogging, emulation support, popcorn mod, fuel & ignition cut, engine code / sensor manipulation, boost by gear, anti-lag, VTEC& i-VTEC support, wideband referencing, with new features constantly being added.

Full Feature List

Honda Tuning Suite includes everything you need to tune your naturally aspirated, turbo, and/or nitrous Honda engine D/B/F/H series engines.  HTS uses universal calibrations which are ROM-based, version independent and features automatic software updates

Note: K/R/L/J series engines are currently in testing by VIP Members
