TUNING THE SUBARU EJ20 (WRX)

This Subaru WRX EJ20 came to FC Tuning for a custom ECU tune. The Subaru Impreza WRX is a well-known all-wheel-drive turbocharged performance car with a strong following worldwide.

The EJ20 engine in WRX form responds very well to a professional dyno tune. With the correct fuelling, boost control, and ignition timing dialled in, meaningful power gains are available without compromising reliability.

We used our custom ECU mapping service to optimise the WRX for road use. The result was a sharper, more responsive car with improved power and economy. A clean, reliable tune for a great everyday performance car.
