The EcuTek ProECU kit can be used for advanced diagnostics, data logging and self tuning for the BRZ/FRS/GT86 + Mazda MX-5 Miata. However, the kit's most impressive feature is to allow EcuTek Tuners to remotely tune customer vehicles. The Tuner supplies suitable ROM files to the vehicle owner. The customer can use the kit to program these ROM files into their own car. If any fine tuning is required, the customer can data log the car and send these logs to their EcuTek Tuner, in order to assist with the tuning process.
