Toyota C-HR 89663-10231 Engine Control Firmware
A catalog overview of Toyota C-HR 89663-10231 engine control firmware and its V1200, HP116 and automatic-transmission labels.
89663-10231 is listed as engine control firmware for a 2018 Toyota C-HR with an automatic transmission. The Toyota 89663 part-number family is associated with engine control computer calibrations. This identification is supported by the catalog filename, although the exact engine and market application are not specified.
Engine control and driving behavior
The engine control module manages engine operation using sensor inputs and calibration data. Its general responsibilities include controlling fuel delivery and ignition timing and coordinating engine torque with the automatic transmission. These functions affect starting, acceleration, fuel consumption and emissions. The catalog entry does not establish which of these settings, if any, changed in this particular calibration.
What the catalog filename identifies
The file CH-R 2018 V1200 HP116 AT 89663-10231.bin identifies the vehicle as a 2018 C-HR and includes the labels V1200, HP116 and AT. The latter denotes an automatic-transmission application. The other labels appear to describe a 1,200 cc engine and a 116-horsepower rating, but their precise catalog definitions are not provided.
The filename does not identify the file as a stock or modified variant, or name a special software feature. The complete calibration identifier is therefore the clearest way to distinguish this record from other C-HR firmware entries.
