Beginning July 19, 2021, California will begin testing uncertified engine control units (ECUs) as part of its two-year emissions verification program.
The new document states that any software not provided by the vehicle manufacturer or approved by the California Air Resources Board will not pass validation. Details of the testing procedure are not mentioned, although, most likely, the test will be carried out trite through the OBD II port of the car.
The test can be completed by installing the factory software. Otherwise, the vehicle must be deregistered.
Tuning ECUs is a common vehicle upgrade option for anyone modifying engines. They usually add power to power plants by burning more fuel, and this, of course, leads to additional emissions.
Let us remind you that Europe has also come to grips with the ecology of the region. Thus, the executive branch of the European Union, the European Commission, on Wednesday announced a number of proposals aimed at reducing emissions. One of them was to reduce CO2 emissions by 55% by 2030 compared to 1990 levels, and by 2035 this figure will rise to 100%.
This means that in 14 years, automakers will not be able to produce vehicles with traditional internal combustion engines, including hybrid models. According to the proposals, the current CO2 exemptions for small automakers producing fewer than 10,000 vehicles per year will also be canceled.
