Fuel Requirements:
Each map lists the minimum required octane. A higher octane fuel can be used safely on a map
designed for lower octane. DO NOT use maps designed for higher octane with lower octane
fuels. Top Tier gasoline should be used where available.

Peak Gains are measured as the absolute maximum value between the highest points of two plots.
Max. Gains are measured as the average maximum value between the highest and lowest point of two plots.
Results may vary. Power as tested on 2013 Focus ST vehicles using these identical calibrations. Generally speaking,
the 87 octane calibrations run slightly lower boost, the 87 and 91 octane calibrations have a richer fuel curve, and a less
aggressive ignition advance map to help compensate for lower octane fuel blends such as those found in Arizona, California,
and Nevada; and/or less than ideal atmospheric conditions. The maps designed for 93 octane are the most aggressive.
*87 octane results are compared against a baseline of 87 octane fuel. 91 and 93 octane results are compared against a 93
octane fuel baseline. Your 91 octane results may be higher than listed above; as a baseline of 91 octane fuel may read lower
than our 93 octane baseline.

Closing Warnings and Precautions:

Use of inappropriate calibration/modification combinations will promote engine damage.

Seek the help of a professional COBB Accesstuner Professional should your Focus ST fall outside of OTS
configurations.

COBB OTS mapping is NOT designed to be used with upgraded aftermarket boost actuators or solenoids.
Doing so may result in much higher than desired boost and potential engine damage. Seek the help of a
COBB Accesstuner Professional should your Focus ST fall outside of OTS configurations.

Top Tier gasoline should be used where available. Use of lower quality fuels can result in catastrophic
engine damage.
Revision Notes:
Stage1

v106 – Minor Update
o

Resolved customer reported issues regarding overboost, limp mode, and bypass valve recycling at partial
throttle.
v105 – Strategy Update
o Remapped throttle translations to improve low pedal position response. Adjusted wastegate settings to improve
spool and boost ramp-up under all conditions. Removed LT maps and replaced non-LT with this strategy update.

v104 / v104 LT – Strategy Update
o Adjusted part-throttle fueling transitions to enhance rare high load conditions.

v103 / v103 LT – Strategy Update
o

v102 / v102 LT – Strategy Update
o

Adjusted fuel, ignition timing, boost control, and grill shutter strategies to optimize vehicle performance.
v101 – Original Release Calibration
o

Adjusted part-throttle fuel, boost control, load and airflow limits, load modeling, and requested torque to improve
the driving experience. Enhanced OEM bypass valve performance and compatibility with aftermarket valves.
Adjusted fuel, ignition timing, boost control (including overboost), camshaft phasing (Ti-VCT), throttle
translations, EcoMode shift indicators, cooling fans, and base programming logic. Reduced compensations for
more consistent power delivery. Adjusted torque, gear, load, boost, airflow, temperature, speed, and rev limits.
v101 LT – Original Release Calibration
o
All settings the same as the standard v101 calibration except for additional throttle mapping. The pedal will feel
more linear in nature when being ramped in. Power levels at WOT are identical, but the car will have additional
power during part throttle conditions.
