YAMAHA YZF R7 has several different versions that use various stock ECUs. If you replace the stock ECU with the aRacer RC SuperX ECU, you may encounter an issue where the radiator hazard light and error code appear on the dashboard due to a CAN-BUS protocol issue. To resolve this issue, aRacer has released the latest version of the firmware. If you are a user of the aRacer RC SuperX, please update your ECU firmware to the latest version.
