The Subaru Legacy ECU executes complicated electronic calculations and its configuration could not be easily changed. Even the Speed limiter's function was proven to be difficult to modify.
We immediately analyzed the ECU that was thought to be too difficult to tune.
We succeeded in fine tuning the speed limiter controls, the ignition/injection timing, and the expansion of the Rev Limiter. In consequence, we upgraded the response at all revolution ranges that would further enhance the driving experience compared to a stock computer.
