Calibration Strategy Information
See our Octane Adjust Ratio technical article for additional information regarding some of the strategies we utilize in these calibrations!

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 vehicle 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 vehicle fall outside of OTS configurations.
Top Tier gasoline should be used where available. Use of lower quality fuels can result in catastrophic engine damage.

Burnout Mode, Launch Control, and Flat-Foot-Shift (LC/FFS) are abusive to the engine, clutch, transmission, axles, and differential. The user accepts all risks and responsibilities when using these features.

Performance calibrations not designed for use when towing.

Revision History:

Version	Notes:
v506	Maps have been updated to eliminate unnecessary DTC suppression.
v505	Added support for 2019 model year; updated revision # for parity for all other Fiesta ST maps.
v504	Updated revision # for maintenance parity with other AP3-FOR-001 Focus ST applications (no calibration changes).
v503	Bug fix for Map Switching Slot Notifier. Anti-Theft calibration fix. Map Switching Notifier improvement.
v501	"Enable Gear Shift Hang" toggle checked based on customer feedback.
v500	All Fiesta ST maps are now v500 and have the new naming convention for Staged maps. "Enable Gear Shift Hang" toggle unchecked. Realtime capable tables (assortment varies) All of these maps are now "Simple SD" capable. New Traction Control default values. (feature is still disabled on OTS, can be enabled using the Accessport)
v400	Improved CCF core logic and user interfaces. Added COBB Traction Control* and 5-Way Torque Maximum Table Selection features. Synchronized platform features (see custom feature documentation).
v221	Fixed a bug that could allow the map switching menu to activate during cruise control and resume activities.
v220	Synchronized platform features (see custom feature documentation). Adjusted ignition correction strategies to allow faster torque delivery in optimal conditions. Adjusted octane learning strategy to enhance post-installation experience. Adjusted LSPI strategy for increased safety margins. Eliminated "Economy Mode" map by incorporating into Slot2 of all Performance Calibrations. Added Burnout Mode Feature (5000rpm). Added Advanced Launch Control functionality. 2500rpm Fuel Cut, 4000rpm Throttle Cut. Added and adjusted 3D Power Demand Fuel and Optimum Power VCT tables.
v202	Adjusted ECT based rev limiter on MY14 Fiesta ST Valet Mode map to prevent FSC from occurring.
v201	Adjusted high load closed loop fueling for part throttle conditions.
v200	Added 5-Way map switching* features as described above. Map slot 1 = Performance – This is the standard OTS map with full performance. Map slot 2 = Pseudo-Economy – This mode disables the wastegate and adjusts WOT fueling for efficiency. This can be used to quickly lower power for times when performance is not needed but is not as thorough as the true Economy Mode calibration. For full economy enhancements please use the Economy Mode calibration.
v104	Adjusted shift assist logic. Adjusted wastegate to prevent boost oscillation on Stage 3 maps.
v103	Added On-the-Fly Launch Control Modes and Flat-Foot-Shift features for Stage 1 Adjusted rev limiter strategy for Stage 1 Original release calibration for Stage 2 and 3 Adjusted fuel, ignition timing, boost control (including overboost), camshaft phasing (Ti-VCT), throttle ramping, 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. Includes On-the-Fly Launch Control Modes and Flat-Foot-Shift features.
v102	Adjusted closed loop fueling targets to ensure all I/M readiness monitor tests were capable of running. Set Launch Control RPM to match Primary Rev Limit to allow full sweep testing on 2WD dynamometers. Adjusted torque targets in all gears at WOT for increased performance.
v101	Added custom volumetric efficiency estimation monitors to the ECU. Adjusted torque limits to prevent rare limp mode conditions. Optimized fuel, wastegate, and timing strategies for overall efficiency and consistency.
v100	Original release calibration. Adjusted fuel, ignition timing, boost control (including overboost), camshaft phasing (Ti-VCT), throttle ramping, 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

*5-Way map switching and COBB Traction Control settings can only be configured with Accesstuner software.
