COBB cracks FoRS ECU and Begins Stage 1 Tuning...

Great info in video and also tips on how to correctly dyno RS AWD!

Baseline numbers and a Stage1 pull.

"On the dyno with our Ford Focus RS. Baseline numbers and a Stage1 pull."

DynoJet / 93 Octane / 92F Ambient / 4th gear pulls

Baseline: 304hp / 340tq

Stg1 (Preliminary): 319whp / 364tq

"The IC blocking plate (which COBB removes) is designed to prevent excessive cooling for vehicles in "cold" climates. In these environments LSPI can become an issue and the car will limit power to prevent pre-ignition. We recommend removing this cover for anyone living in environments that are regularly above 50F."

"We've run the car several times back-to-back and have had no reduction in power. Each time, the overboost timer was under the limit."

Can't wait to see more numbers once the tuners start getting their hands on the RS.

This is a big variation from Mishimoto's numbers.
In the video Cobb (Braden Berger) mentions and gives some insight as to how to prep and dyno the AWD correctly...Not sure how Mishimoto prepped the RS before dyno?

Ford Focus RS Power Gains and Development

Ford Focus RS Power Gains and Development

View attachment 14

June 30th – Preliminary Stage 1 Power Gains

"Our engineering team learned a lot with their time on the RS in England. After more time on our dyno here at COBB they were able to come up with a safe and reliable Stage1 calibration that still offers some healthy power gains. The below will be similar to the released Stage 1 Off The Shelf map that will come on the Accessport!"

When our baseline numbers for the Focus RS were first released, there was a lot of talk about them being inflated and even more concern surrounding the fact we dyno’d the vehicle in FWD instead of AWD mode. There’s good reason for that!

The Focus RS does not have a center differential like other AWD vehicles in its class. Instead, there is an electronically controlled clutch pack that sends a variable amount of power to the rear differential. This system is called the Rear Drive Unit or RDU. When the RDU is active (sending power to the rear wheels), it causes the rear wheels to spin faster than the front. Keep in mind that the dyno rollers are linked front and back so they spin at the same rate. With the rollers spinning at a constant rate, and the vehicle trying to spin the front and rear wheels at different rates, things don’t mesh well. When this is the case, the car actually “thinks” it is losing traction which results in it intentionally limiting power. The best way to dyno the vehicle is in FWD mode with the RDU disconnected. Even if we were able to prevent the car from limiting power in AWD mode, the gains expressed as a percentage will be identical in either FWD or AWD mode. The actual number isn’t too relevant as it will be different with varying dynos and conditions. Check out another post on Interpreting Dyno Results for more details.

The Accessport for the RS platform will be released soon! Stay tuned for more details on the release and information on hard parts and Staged Packages to come!

It's amazing they are moving this fast. Haven't received my RS yet, but I'm already contemplating picking up the Accessport first lol.
