![]() HDFX – High Degree of Freedom Executive.MAP – Manifold Absolute Pressure (Post-Throttle).ECU – Engine Control Unit (also known as PCM).DC – Duty Cycle (used with various solenoids).Care should be taken to adjust these temperatures with the appropriate sensors in place to ensure optimal power delivery and engine safety are achieved. This will result in poor performance and use excessive fuel. During this mode, additional fuel is injected in an attempt to cool the car down and bring conditions back to normal. Over-temp Conditions – There are numerous watchdogs in the ECU that can put the car into an over-temp mode. The axes are generally index based and may require manipulation to both the index and/or the data to properly display graphs or to utilize greater breakpoint resolution. On tables that would require it, we have broken these out for editing in separate folders. In these tables both the X and Y axis have "paired" data. "5D" 3D Tables – The Ford ECU uses a new style of 2D axes in select 3D tables. To see a good example of an effective timing strategy, compare and contrast a few of our various OTS maps. All of these must be touched to produce desired results. There are up to 16 primary tables for each method, along with accompanying compensations. ![]() The ECU also allows full dynamic advance and retard based on octane learning and knock sensor feedback. It consists of four primary methods to control spark: MBT, Borderline, Cylinder Pressure, and Pre-Ignition. Ignition Control – The Ford ECU has an incredibly complex timing strategy. Engine torque is calculated based on numerous variables such as: pedal position, air flow, boost and RPM. While certain tables are marked as "Open Loop", they are labeled as such to distinguish the difference between stoichiometric operation and air fuel targets during power enrichment (such as wide open throttle).īoost Control – These vehicles do not directly target boost in stock form but rather engine torque. See our OTS maps for effective examples.įuel Control – Ecoboost engines operate in a constant closed-loop state, constantly utilizing the A/F values in its tables and making adjustments via its equipped wide-band O2 sensor. ![]() We recommend adjusting these limits higher to take full control of the throttle. There are two main offenders that will result in throttle closures: Load and Boost. The factory tune allows the throttle to close to less than 20% (of the 82% max) which can result in extremely consistent torque delivery, but neutered performance. Throttle Closures – The primary method of controlling torque on these cars is done with the assistance of the drive-by-wire throttle system (factory tune). While some Ecoboost vehicles do have a MAF sensor in place, it is not used for airflow calculations. MAP Based – These vehicles use a MAP based airflow system. Please contact COBB Support if you have any questions.Here we will go over a few of the basic details and terminologies that are specific to Ford before we begin tuning on a COBB Accessport equipped Ford Ecoboost vehicle. Warning! Installation of this Accessport over anything other than OEM or COBB software may result in ECU/TCU failure. With 165% more surface area over stock, the intake produces more air-flow and a more audible turbo sound when building boost at low RPM. With 165% more surface area over stock, the intake produces more air-flow and a more audible turbo sound when building boost at low RPM.Īlso, we combined the improved airbox design with a high flow, dual inlet, tapered-oval filter. Also, we combined the improved airbox design with a high flow, dual inlet, tapered-oval filter. Powder coated tubing, composite material, and a COBB nameplate transform the engine bay to look as sharp as the iconic exterior. The injection molded - fiber reinforced airbox lid incorporates a closed-cell foam gasket to seal the filter from mud, dirt, and debris. The factory piping from the air-box is replaced with dual 3" mandrel bent aluminum tubing to maximize airflow while custom silicone couplers ensure perfect OEM-like fitment. And what's looks without brains? More processing power, memory, and storage to flash faster while saving all of your maps and logs. Fully customizable from the look (multiple bezel colors), layout (set up race, street, or dyno gauge clusters), and mounting options (choose from 1,000s of standard vehicle mounts). Simple ECU flashing with gauge package! The new in-cabin mountable Accessport V3 has a large, full color, higher resolution screen which allows you to monitor up to six parameters in real time.
