ECUFILES engineers worked hard and developed safe but very powerful tuning files for BMW vehicles with MEVD17 ECUs. In our system, you can get access to Catalyst Heating OFF / Cold Start OFF tuning files. By downloading our tuning files you can easily switch the cold start function OFF!

When drivers remove catalyst or when they install a sport exhaust they want to delete the Cold Start Mode. When this mode is ON, and the car is cold, the RPM will jump higher to heat up the catalyst. With this feature, the catalyst gets heated up, and it works optimally to lower the emissions. But, when the catalyst is removed from the vehicle or sport exhaust is added catalyst heating option will create a loud and disturbing sound.

With our Catalyst Heating OFF / Cold Start OFF Tuning Files you can help your clients to get rid of annoying sound and keep the RPM on a low level soon after the car’s engine starts.
