This is actually quite common with aftermarket tuning for the past decade. Traditional ECU tuning you replace your car's ECU with one with a modified (chipped) ECU. Now, there are bolt-ons that connect through the OBDII port. They modify shift points, change timings, and air fuel mix ratios. And do this without voiding the warranty.
