The AccessPORT is the industry leading OEM ECU flashing, managing and monitoring assistant. Unlock power hidden within the ECU by replacing conservative factory settings with more aggressive calibrations. The result is impressive gains in torque and horsepower while maintaining a high degree of safety. The AccessPORT comes with pre-installed maps that are optimized for common performance modifications.

Flashing the factory ECU for more power is just the start of what the AccessPORT is capable of. The AccessPORT's full-color screen, intuitive interface and extensive features allow you to easily interact with your car in ways you never thought possible.

Results may vary. Power as tested on 2013 Focus ST vehicles using these identical calibrations. Generally speaking, the 87 and 91 calibrations run slightly lower boost, 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.
*Legal only for racing vehicles which may never be used, or registered, or licensed for use upon a highway.


Anyone can install the AccessPORT. No computers, wire cutting/splicing or tools of any kind are required. The AccessPORT is one of the easiest modifications you can make to your high performance vehicle. No tools are needed and no computer connection is required. Just plug the AccessPORT into the car's OBD-II port and follow the simple step-by-step on-screen instructions. In just a few minutes you will have a new performance map loaded on your ECU and be ready to experience the additional power and improved driveability of a proper tune tailored to your vehicle's modifications.

The AccessPORT comes preloaded with several performance maps for common modifications and includes access to a free online database of additional Off-The-Shelf maps.


Store up to 100 maps in the AccessPORT. Change maps whenever you want and be ready for any situation. 

The AccessPORT can store up to 100 maps so you can be ready for any situation. Use the Change Map function to browse the maps stored on the AccessPORT and select the map most appropriate for what you want to do:

Running down the drag strip to beat your last ET? Change over to your high boost map.
Heading out on a long boring highway drive? Perfect time for that fuel economy map.
Parking your car overnight in a risky area? Load the Anti-Theft map to prevent start-up. 
(for some applications)
Handing your pride and joy over to a valet for dinner?  Switch to the Valet map to limit performance.

It's like an MP3 player for your engine. The "songs" are maps and the "volume" is the throttle!


Want Gauges? No problem. The V3 now supports up to 6 fully customizable gauges with 1/1000 resolution. Monitor all the parameters you want to see and customize each layout for street, strip or track.


Monitor OEM sensor data on-the-fly. Use the AccessPORT as an additional set of gauges to monitor data directly from the ECU. 

Gauges allow you to view sensor data and calculated values in real-time right on the AccessPORT. There is no need for a clunky PC to ride shotgun with you in the passenger seat. Just plug the AccessPORT into the OBD-II port, select Live Data from the menu and choose a monitor to view. Any monitor that can be data logged can also be viewed in real time using this feature. Live Data can function as auxiliary gauges to supplement the stock gauge cluster, or it can be used to help in fine tuning custom calibrations.

Unlike dedicated auxiliary gauges that can clutter up your dashboard, the AccessPORT functions as soft gauges, allowing you to decide what gauges to display. Some examples of gauges are:

  • Throttle Position
  • Boost Pressure
  • Ignition Advance
  • Wastegate Duty Cycle
  • Mass Air Flow
  • Intake Temperature
  • Air/Fuel Ratio
  • Calculated Load
  • Vehicle Speed
  • Bypass Valve Mode
  • Coolant Temperature
  • and many more...

As you can see from this sampling, some of these monitors would be impossible to duplicate with a traditional auxiliary gauge.


Record multiple data channels simultaneously for in-depth evaluation of engine performance. Stores up to 10 hours. The AccessPORT functions as a hand-held data logging device. There is no need to drag your laptop computer out to the car. Just plug the AccessPORT into the OBD-II port, select Data Logging from the menu and choose which monitors you wish to data log. Choose as few or as many monitors as you like. Hit enter and data logging begins. Once the data gathering is complete, hit the enter button again. The data is stored as a data log file within the AccessPORT. The AccessPORT can store up to 10 hours of data logging.

The data logs are stored on the AccessPORT for as long as you want them there. Just unplug the AccessPORT and put it in your pocket, back-pack or briefcase. To analyze the data, simply plug the AccessPORT into any PC or Mac and download the data logs to view in your favorite spreadsheet or graphing software.


Welcome to your own performance evaluation suite! Measure 0-60mph time, 60 foot and 1/4 mile ET's, and Trap Speed. 

Every AccessPORT has built in Performance Monitors. These are great for showing the performance of your vehicle in the current state of tune with the modifications you have installed as well as helping to quantify performance gains when you make additional modifications. These are also great tools to help you improve your skills at the drag strip. It's like printing off your own time slip any time you want!

The following Performance Monitors are available:

  • 60' Time:¬†Elapsed time to 60' distance. Indicates how well your car is hooking up off the line.
  • 330' Time:¬†Elapsed time to 330' distance
  • 0-60 mph:¬†See where your car stacks up against the 0-60mph times published in the major car magazines.
  • 1/8 Mile:¬†Elapsed time and vehicle speed at 1/8 mile distance (660').
  • 1000' Time:¬†Elapsed time to 1000' distance.1/4 Mile: Elapsed time and¬†vehicle speed at 1/4 mile distance.


The screen of the AccessPORT will flash brightly to warn you when the engine has exceeded the limit you set. Perfect for use as a shift light! As an added bonus, the AccessPORT screen also functions as a Rev Warning Light. Simply enter the RPM you want the Rev Warning Light to activate at. The screen will brightly flash red and white to alert you when that RPM has been reached, while simultaneously showing any Live Data monitor!


Read engine trouble codes to diagnose issues. Clear them when resolved. Prevent expensive trips to the dealership. 

The AccessPORT allows you to read engine codes to help troubleshoot issues and potentially save you from an expensive trip to the dealership. A brief description of the trouble code is also provided, which is handy when you don't happen to have a shop manual in your pocket.

The AccessPORT will read any trouble code reported by the ECU. In most cases, this equates to hundreds of trouble codes and descriptions to help diagnose issues where ever you may be. Once the issue is resolved, the AccessPORT can be used to clear the codes to turn off the check engine light.


Restore your vehicle's ECU to its original factory configuration simply by performing the Uninstall operation. In the event that the car must be returned to the stock configuration, the AccessPORT can be completely removed and the ECU restored to its factory condition. Once the AccessPORT is uninstalled, it can be installed on any vehicle the AccessPORT part number supports. Since the AccessPORT can be uninstalled, combined with the ability to update the AccessPORT firmware via the internet, it retains a high resale value.

Makes your ST the way it should have always been!

This is truly a five-star experience. The item arrived FAST and the instructions are simple and easy to follow. When you hook this up to your car, it takes a while (ten minutes, approximately) for it to download your current ECU mappings. Then you can flash any of a number of mappings depending on your situation. That only takes a few minutes to flash and then you're up and running. The difference in my 2015 Focus ST3 was pretty dramatic. The most noticeable change is the added torque -- when you accelerate, it feels like the car is unleashed, and it really moves! I purchased the FSWERKS tune, so the added 75 foot-pounds of torque is quite substantial. The car operates altogether more smoothly, as well. Shifting and idling are improved. I commute 35 miles each way every day, and I don't normally drive it hard, so my gas mileage actually improved by at least 1 mpg. There is really no downside to the accessport, and you can return to your stock mappings at the touch of a few buttons. As always, it's a pleasure to deal with FSWERKS. They are always very helpful and patient, and they always take their time to discuss things and answer all of your questions.

Thanks very much for the great feedback Stephen :-)



With all the added extras I have installed on this ST, Cat Back, Down Pipe, Cold Air Induction, the Cobb put it all together. Can't wait to purchase the intercooler kit from FSWERKS. Running Stage 3 right now, what a difference in performance and raw power. Thanks FSWERKS

Thank you Bill :-)


Good, but spend the $50 extra for the FSWERKS tune.

Well I got this, and works great... love all the details it provides. I later saw the additional FSWERKS tune for $50.. I purchased it and it is MUCH better! Wow, This is a must if you have a Focus ST. Buy the flasher WITH the tune, save yourself $50 since they give you a $50 gift card... My loss, didn't know. So 4 stars for this unit, 5 stars with the FSWERKS tune... great stuff guys, keep up the great work!
