Accessport V3 — TCM Flashing Update
Overview
Already own a COBB Accessport for your F-150 EcoBoost 3.5L? This update unlocks TCM (transmission control module) flashing on your existing Accessport — adding Off The Shelf transmission tunes that adjust shift points, shift firmness, skip-shift behavior and torque limits to fit your preferred driving style.
The Accessport remains the world’s best-selling, most flexible and easiest-to-use ECU upgrade for your Ford F-150. This part upgrades an AP3-FOR-006 to AP3-FOR-006-TCM for the 2017–2019 F-150 EcoBoost 3.5L — select this part number only if you already own an Accessport for that vehicle.

2017–2019 Ford F-150 EcoBoost 3.5L — for owners who already have a COBB Accessport (AP3-FOR-006) for this vehicle.
This is an upgrade applied to an Accessport you already own — it is not a standalone Accessport.
FFP knows the EcoBoost Mustang.
COBB is the standard for EcoBoost Mustang performance.
The S550 EcoBoost responds hard to the right parts — and COBB has spent more time on this platform than anyone. From the Accessport ecosystem to bolt-on intakes, exhaust, and suspension, it is proven, repeatable hardware. That is why we stock it.
Want the work done by techs who build EcoBoost Mustangs every week? Drop the car in Thousand Oaks. Prefer to install it yourself? Every COBB part ships with clear instructions and direct-fit hardware.
