The full breakdown.
Accessport V3
Overview
Simple ECU flashing with a full gauge package. The new in-cabin mountable Accessport V3 has a large, full-color, higher-resolution screen that monitors up to six parameters in real time — fully customizable in look (multiple bezel colors), layout (race, street or dyno gauge clusters) and mounting (thousands of standard vehicle mounts). More processing power, memory and storage flash faster while saving all of your maps and logs. This is your new Accessport.
The Accessport is the world’s best-selling, most flexible and easiest-to-use ECU upgrade solution for your Ford. Unlock power hidden within the vehicle by replacing conservative factory settings with more aggressive calibrations — follow COBB’s staged upgrade path with pre-loaded Off The Shelf (OTS) maps, or run custom mapping for any modification level. It’s the last engine management solution you’ll ever need.
COBB Stage Power Gains
The Accessport delivers power through COBB’s staged Off The Shelf calibrations. Published gains for the 2015–2017 Mustang EcoBoost:
| COBB Map | Peak Gains | Maximum Gains |
|---|---|---|
| Stage 1 — 91 octane | +3% HP / +19% TQ | +20% HP / +22% TQ |
| Stage 1 — 93 octane | +4% HP / +21% TQ | +22% HP / +24% TQ |
| Stage 2 — 91 octane | +18% HP / +24% TQ | +21% HP / +28% TQ |
| Stage 2 — 93 octane | +20% HP / +26% TQ | +23% HP / +30% TQ |
Maximum gains, 93-octane maps. Figures from COBB’s published Map Notes for the 2015–2017 Mustang EcoBoost, tested on top-tier fuel; 2018–2023 models run their own model-specific COBB calibrations. Results may vary.
The Staged Upgrade Path
Each COBB stage layers proven hardware onto the Accessport and its matching calibration. Start at Stage 1 and build up — every stage is fully reversible.
Every OTS map ships with COBB’s 5-way map switching — Max Performance, Mid-High, Mid-Low, Low, and an Economy mode that adjusts fueling and timing for efficiency — selectable on the fly without re-flashing the ECU.
