Volkswagen Golf GTI & Golf R (Mk7 / Mk7.5) ECU tune

The EA888 Gen 3 is one of the most rewarding engines to calibrate, and Simos 18 is a controller we know well — including its checksums. We build the file around your hardware and your fuel, and we revise it from your logs rather than shipping a one-size map.

Volkswagen Golf GTI & Golf R (Mk7 / Mk7.5) tuning questions

Do you tune the DSG as well?

Transmission calibration is a separate controller and a separate job — open a ticket and we'll quote it with the engine tune.

GTI or Golf R — does it matter?

Yes; they share an engine family but not a calibration. Tell us which car and which software you're on.

Do you remove emissions equipment?

No. Catalysts, sensors and monitors stay in and working.
