It’s been a long overdue wait for our new Ford Focus RS to arrive at the shop so we could start tearing into it and begin R&D. First things first…tuning. Being a COBB Protuner, we wanted to utilize the COBB Accessport for ECU calibration. The Ford team at COBB has developed very powerful software that gives us full access to the factory ECU which allows us to recalibrate it to our liking. We started out with the car in completely stock and strapped it on our Mustang Dyno for some baseline pulls. We unplugged the RDU as instructed by COBB and the RS laid down some very nice numbers for a bone stock car: 280 whp and 331 wtq and yes that is the window sticker still installed.
Next, we loaded up the Stage 1 - 91 octane OTS map from the COBB Tuning Accessport to see what changes occur. This map really woke the car up, putting down 296 whp and 358 wtq which was very impressive for an OTS map on an all stock car. Of course we couldn’t stop there; we used the Accesstuner Pro Software to create a custom ECU calibration. After a few small adjustments we were able to squeeze a little more out of the RS. Peak numbers 302 whp and 374 wtq and decided to stop there for now as we were really happy with the results.
Stay tuned, we have more plans for the RS to include adding some E85 to get an E30 mix and some new hard parts. But for now check out the smoke show..
