You can obtain improvements in your Mini's power and fuel utilization by availing yourself of the technology provided in ECU remapping or chip tuning. Both of these procedures will give you significant gains in power, torque, fuel economy, and other engine functions. ECU remapping is designed for Minis manufactured after 2000, while chip tuning is the process applied to older models.
ECU (Engine Control Unit) remapping access information placed on an EPROM chip by the manufacturer to govern how the engine operates. Because these values are generic, they are rarely best-suited to your particular driving needs. The data values on the chip can be changed by the remapping process. This involves reading the data via your Mini's on-board electronic diagnostics technology and reprogramming the chip to change the stored values to values that will enhance the engine's performance.
Chip tuning accomplishes the same alternations of the stored data but requires removal of the ECU from the Mini in order to access the chip. Once the data has been changed, the chip and ECU are reinstalled, and you are on your way in a more powerful and smoother-driving Mini.
The performance gains are the same with each procedure, since they are essentially the same. The only difference between them is how our technicians get to the data stored on the ECU memory chip.
