For workshops: diagnostics, fault codes and remap data
Fuel-injection workshops use this data with the BikeStudio diagnostic tools: HDiag Pro for Honda PGM-FI and YDIAG Pro for Yamaha read live sensor data (RPM, TPS, engine temperature, O2), read and clear fault codes (DTC / blinking MIL) and HDiag Pro also reads and writes Honda ECU flash for remapping (an ECU tuner with 2D/3D maps). The AFR Meter helps tuning and ECU remapping with the live air-fuel ratio on the phone. Part number, ECM ID, calibration and flash size in the database help pick the right remap file.
