Here at COBB we are constantly looking for ways to improve our product and in turn help you guys make more power and improve the way your cars drive. Earlier this week we pushed out an update to Accesstuner and Accessport firmware that includes some exciting updates as well as a couple of minor maintenance items.


Volumetric Efficiency (VE) Tuning
As Focus ST and Fiesta ST tuning exceed typical bolt-on hardware into aftermarket turbos and camshafts, the factory VE calibration becomes inaccurate. The mysteries of VE tuning and how to interpret the vast amounts of "Speed Density" tables have been simplified in the March release. New data monitors have been added to help tuners review the system changes and perfect their tunes. Additionally, the COBB Ford engineers have developed a VE worksheet (here) to guide users through the refinement process.

Advanced Wastegate Control for Fiesta ST
Additional discovery work shows the vast complexity of boost control through an advanced wastegate PID Controller. A comprehensive table and monitor list update allows tuners to fine tune the entire wastegate control system.

OTS Map Updates
v101 Fiesta ST maps updates:
Estimated VE and Advanced Wastegate Control Monitors.
Improved Launch Control Logic.
Increased torque limits to prevent rare limp mode conditions.
Optimized power demand fuel settings for better overall efficiency.
Optimized ignition timing strategy for more consistent results.
Adjusted wastegate tables to prevent rare cases of overboosting.

v202 Focus ST map updates:
Estimated VE Monitors
Stage1 87 Octane map support
Aftermarket Bypass Valve Support

Focus ST1 - Clock / Date Fix
Fixed bugs associated with Reset ECU to address ST1 clock and date setting issues. Any user encountering the clock / date settings bug can simply run "Reset ECU" from the Accessport to reset the control panel.

Additional Table and Monitor Updates
More useful tables and monitors!

Added Tables:
Lowside FP Duty Cycle (Min)
Lowside FP Duty Cycle (Max)
Lowside FP Voltage (Min)
Lowside FP Voltage (Feed Foward)
LSPI Load Limit Blend Modifier (OAR)
LSPI Load Limit Blend Modifier (PI)

Lowside FP Input Voltage​

Do you have an idea or a suggestion that could make more power or enhance the driving experience? Chances are we can make it happen! Submit your ideas and suggestions to [email protected] and we’ll do our best to incorporate them in future updates.

I have had my access port for a few weeks now, i am experiencing a bit of an initial on throttle delay or lag, (this was in both the 91 (100 and 101 map). it would be great if this could be eliminated. The stock map did not have that delay, so i am sure it could be programed out.

second question, do you guys have access to the electric steering? it would be great if you could make the curve have 10-20% more resistance.

I believe it's only with ATR. That was a main reason I bought ATR. Even in neutral clutch out it still enables launch control. But I'll be mad if they put in on the OTS maps as I spent 150$ on the ATR. Lol

So we do have LC now?? Also COBB, can you do something in the tune that allows for brake-boosting? It seems now once you make ~15-18psi it'll just dump the boost.

I think it's in spark timing or fuel or something along the lines. It's in one of the folders toward the bottom. I know one of the folders say launch control. It was to find I thought. You set your rpm you want to launch at. Then you put the mph you want it disengage. So example. You have it 4mph. After 4mph you can redline it on a rev.

Once it's in the tune, it's active, and you have to go over 4mph (or whatever) to disable it.

No no. You just load whatever map your using into ATR. Then you go to launch control and set your Rpms and what mph it disengages. Then save the map. Then go to the accesport software and load the map so it installs to your maps on the v3 then go plug it into your car. Flash the map with LC to the car. Then start her up. Put your foot the floor and it'll work. Lol. There's no buttons or anything. It's always there.

ATR is the additional race software right?
Yes. It allows you to do a whole lot of moe tuning to the car. That is if you know what your doing. Or if your gonna get a tune done by a local tuner you need this software.
