The ECU Flash upgrade for the Scion FR-S, Subaru BRZ, and Toyota GT-86 2.0L cars is quite an amazing upgrade. Not only can the ECU flash get ride of check engine lights from catless exhausts, it can also raise the rev limiter for shifting, and also open up your top speed limiter. The biggest difference with the VR Tuned ECU flash for the Boxxer engine is getting rid of that HUGE torque dip at the low RPMs and making the throttle much more responsive. These ECU’s can be flashed via OBDII port for local Arizona customers or mailed in from out of state/country where we can bench flash them. Ready to order yours?
