Day One
Cars with an ECU for emisssions control have had the mapping for passing legislations testing in it since day one. (Uhm, also with NO ECU, the mechanical/electrical sensors/valves/whatnot would have a time/temperature/pressure/whatnot profile to meet test requirements.)
Mapping is always suited to the test the legislator requires the car/vehicle to pass. All other circumstances that are not in the test just are mapped according to common sense to get a balanced economy/power/lifetime/u name I.T. performance of the car and drive-train.
Legislators testing-cycles do not conform with individual driving styles. This has been an issue for years and years and .....
So What Is Cheating?????????
BTW this is why you never get the mileage that test-results promise.
Biting the hand that feeds IT
