CarEcuFile

I founded CarEcuFile in Istanbul in 2014. We develop ECU software for private and commercial customers, delivering tuning files that improve both performance and fuel efficiency. Quality and customer satisfaction come first, and our experienced engineers keep pace with every development in automotive software.

For more than a decade we have served customers in Türkiye and around the world. Our Istanbul headquarters is open six days a week during business hours. Our goal is simple: to deliver the right solution as quickly as possible.

Demirkıran ECU

I founded Demirkıran ECU in 2016. Today our team serves customers through branches in dozens of cities across Türkiye. The business is built on quality, integrity and precise workmanship, and we continually invest in new technology.

We repair and program electronic modules that dealerships cannot fix, or can only replace at high cost, using specialised equipment and rigorous procedures.
