TUNING THE SUBARU EJ20 (WRX)

This Subaru Impreza WRX EJ20 Tuning session was carried out on Redline Motorsport’s own Subaru Impreza WRX. The car was built to the RM_S1 package specification.

Redline Motorsport is a well-known preparation and performance outfit. The RM_S1 package is a carefully developed setup designed to get the most from the Subaru EJ20 engine in road and track use.

We carried out custom ECU mapping to suit the full specification of the build. The tune was tailored to the exact modifications fitted, ensuring the best possible power output and reliability.

The result was a well-sorted Subaru WRX with strong, linear power delivery. A great package from Redline Motorsport, backed by a professional custom tune from FC Tuning.
