ECU remapping or chip tuning can transform the performance of your Sea t engine . Both procedures involve downloading memory chips in the Engine Control Unit (ECU), which are responsible for storing instructions about how your engine runs. This information can then be altered to provide optimal values. In the past, vehicle engines were tuned using mechanical methods, but modern Seats utilize electronic procedures.
The only difference between ECU remapping and chip tuning is how the memory chip is accessed. Remapping can be done through the OBD/OBDII port using on-board diagnostics available in vehicles made after 1999. Chip tuning, which is used on pre-2000 Seats, requires physical removal of the engine from the Seat, and then removing the memory chip to alter its values.
Both methods offer the same performance enhancements and will give new and older Seat drivers a better ride, faster response, and more power.
