Introduction

Ford has recently issued a TSB for select 2015-2016 Mustang EcoBoost and 2016 Focus ST vehicles. The TSB, titled 'TSB 15-0192 2.3L GASOLINE TURBOCHARGED DIRECT INJECTION (GTDI) - EXCESSIVE EXHAUST SMOKE AFTER EXTENDED IDLE', instructs the Ford dealer to perform a replacement of the crankcase vent oil separator. Ford also updates the car's engine control unit (ECU) with their latest calibration. 
We have added support for Ford's new ECU type being flashed to cars during this process. This includes new Accessport firmware, Accesstuner software, and off-the-shelf (OTS) maps (v210 or later).

Frequently Asked Questions (FAQ)

Which vehicles are part of Ford's Oil Smoke TSB?

• 2015-2016 Mustang EcoBoost applications
• 2016 Focus ST

Only cars within a specific production date range are included in this TSB. Cars built prior to 1/31/16 may need to have this service performed.

I've been running an Accessport with one of the above vehicles. Why is Ford's TSB important?

Any factory ECU tuning solution, including the Accessport, uses the factory's calibration and logic as a base and improves upon that. Depending on when and how the map was created, its base ECU may be one that is part of Ford's current TSB. While the modified tune in an Accessport map could potentially negate some or all of the original factory problem, given the potentially adverse effects of oil consumption, we are recommending that all our customers with the above vehicles upgrade to revised maps outside of the TSB range.

I've been running a COBB off-the-shelf (OTS) map with one of the above vehicles. What do I need to do?

If you are running one of our COBB OTS maps with one of these vehicles, we highly recommend that you update your car's ECU to the appropriate v401 or later OTS map, even if your specific vehicle is not subject to Ford's TSB. Some OTS map versions do NOT use a base ECU calibration that is part of Ford's TSB (such as the 2015 Mustang EcoBoost  v400). At this time, we are only supporting the TSB ROM files for the 2016 applications until a determination can be made on the effectiveness of the calibration on 2015 vehicles.

Where can I find an updated v401 or later OTS maps?

• Update your Accessport to the latest firmware version (version 1.7.2.0-13210 or later) using the Accessport Manager software. Once on the latest version, all the pre-loaded maps on the Accessport will be updated with the latest maps (v401 or later). If you need any OTS maps that have been deleted previously, you can restore the newest maps using the Tune → Restore OTS Maps option on the Accessport.  
  
  

I am running a custom tune from a COBB Protuner with one of the above vehicles. What do I need to do?

You will need to contact your Protuner so they can advise you on the map upgrade process for your specific scenario.

I own a 2015 Mustang EcoBoost, should I still update my Accessport maps and reflash my car?

Yes. Even though your ROM is not changing at the moment, we have several updates included in our v400 and v401 map files.

Now that I have an updated map, how do I install it?

• Update your Accessport to the latest firmware version (version 1.7.2.0-13210 or later) using the Accessport Manager software.
• With the Accessport connected to the car, use the Tune → Change Map function to install the appropriate upgraded map to your car's ECU.
  
  

I'm attempting to install an updated map but the map is grayed out when I go to select it. What is causing this?

Short of using the wrong map for your ECU, it is likely that you did not update your Accessport to the latest firmware version. This is required in order for the Accessport to recognize a map created in one of the new ECU revisions.

Is it possible to have the Ford dealer perform their TSB with my Accessport still installed?

No, the dealership will not be able to perform their ECU update when the Accessport is installed, even if you use the latest Accessport map that matches what they install. You will need to fully uninstall the Accessport by connecting to the car and selecting the Uninstall menu option and completing that process. WARNING: Changing maps to a "stage 0" stock mode map (or any other map) will NOT allow the dealership to perform the TSB update - you must use the Uninstall option only. Keep in mind the uninstall procedure places an OEM tune on the vehicle. If your car is mechanically modified, you may need to return the car to a mechanically stock configuration to drive safely on the factory tune.

If the Ford dealer performs the TSB on my car, do I still need an updated map when I re-install the Accessport?

Yes, you'll still need to update your Accessport firmware and reflash the car with a v210 or newer map file (or an updated custom tune from your Protuner) to avoid running an old map after the TSB.

Doesn't a custom tune override Ford's stock tune and therefore won't be subject to the oil smoke issue that Ford is addressing?

This is a bit of gray area. It depends on the exact changes made in the map and which map was used as a base. To play it safe, you will want to have your Protuner update your custom map(s).

If I install an Accessport map with the fix, do I still need to get the Ford TSB done?

You may still want to get the TSB done from Ford so there is a record that the TSB has been performed. Part of Ford's TSB is to replace the crankcase vent oil separator on the vehicle, which may alleviate smoking issues further than an ECU calibration can. Some states also require that all TSBs be satisfied before a vehicle's registration can be renewed.
