2013 Focus ST, calibration development vehicle


Recommended Posts

As for the car itself:


What are the pros/cons?

Actual mpg?

Any 'street beats' at red lights?

How is the torque vector and traction control?

Does it have the active grill shutters?

Does the active sound symposer make you grin?


The list could go on...but for now (please):

Stock hp/tq?

Stock hp/tq with overboost?

Vehicle is still in development:

1. Flashing works

2. Software works

3. Firmware and software will work back and forth with calibrations to test stability, find parameters and ensure flashing is solid, then it will go to QA to test.


Will have more information as tests are passed. Completion should be within 2 weeks.

Surely is... I love it and at 25k, sounds like a good value. If only it had AWD... With all that power and FWD, it will probably be like mazdaspeed3, very hard to launch on day to day driving...

Please let us know your feedback if you drive it... I would also recommend to try it on a sunny day And on a rainy day...

Stock run data below 87 Octane. Note how Engine coolant temperature plays a massive role in end power output once you get to real world temperatures. Also note that Cat over temp is also to blame for the upper RPM power reduction.


Runfile 012 @ 145 degrees ECT

Runfile 013 @ 185 degrees ECT

Runfile 014 @ 196 degrees ECT


As temperatures increase COT kicks in and timing decreases.
