Introduction

Nissan issued a technical service bulletin (TSB) for select 2009, 2010, and 2011 USDM GT-R models. The TSB, titled 'NTB10-127', instructs the Nissan dealer to perform a ECM update for vehicles encountering DTC P0133 AND / OR P0153.  We have added support for Nissan's new ECU type being flashed to cars during this process. This includes new Accessport firmware, Accesstuner software, and off-the-shelf (OTS) maps (v701 or later).

We've compiled the following information to help you transition your customers to new updated maps. Please read the end-user FAQ at the following link first. This contains basic information about Nissan's TSB and the Cobb updates.

Frequently Asked Questions (FAQ)

Which vehicles need updated maps?

  • 2009 Nissan GT-R USDM
  • 2010 Nissan GT-R USDM
  • 2011 Nissan GT-R USDM

Customer car is one of the above vehicles, but is not part of the TSB. Do they still need an updated map?

Yes, in most cases. More detail below.


How do I update customer maps?

The updated Accesstuner software (version 1.9.1.0-12808 or later) allows you to convert your maps. See How do I transfer a "Pre-TSB 1" tune to the "TSB 1" ECU?:

2009 Nissan GT-R USDM:

  • "(Pre-TSB 1)" - This is the original ECU that existed in the prior software and is based on the ECU subject to the TSB issue. 
     
  • "TSB 1" - This is the newest ECU that Nissan is installing as part of the TSB. This includes changes and logic updates from Nissan to address the DTC P0133 AND / OR P0153 issue.  Due to ECU differences, old maps cannot be opened in this ECU. We suggest you update all your 2009 GT-R USDM customers to this new ECU.

2010-2011 Nissan GT-R USDM:

The updated Accesstuner software (version 1.9.1.0-13050 or later) allows you to convert your maps. See How do I apply the TSB fix to an older calibration file?:

  • "2010 Nissan GT-R USDM" / "2010 Nissan GT-R USDM Speed Density" - These ECU definition files contain updated patches to address the DTC P0133 AND / OR P0153 issue.  

  • "2011 Nissan GT-R USDM" / "2011 Nissan GT-R USDM Speed Density" - These ECU definition files contain updated patches to address the DTC P0133 AND / OR P0153 issue.
     

My customer is receiving an "outdated ROM" message on their Accessport when they go to install or uninstall. What does this mean? 

Newer Accessport firmware will present this message (see full message text below) when attempting to install or uninstall the Accessport.  This is to let the Accessport user know that an optional ROM update is available to support a Nissan ROM TSB.  If you choose to use the updated stock ROM, v701+ OTS maps (or an updated custom tune from your Protuner) will be presented to you during install.  Alternatively if you are uninstalling, the latest stock ROM from Nissan will be flashed back to the ECU.

2009 Nissan GT-R USDM: I've sent my customer an updated map but the map is grayed out when they go to select it. What is causing this?

Short of sending them the wrong map for their ECU, it is likely that your customer did not update their 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.

With this initial release, you will need to manually copy your tune from the old ECU You can use the "Compare to Accessport Map" Feature to update Pre-TSB tunes to the new ECU as follows:

  • Open two instances of the latest Accesstuner software (simply run Accesstuner twice from the same shortcut). 
  • In the first instance, open the old ECU and open your existing map. 
  • In the second instance, open the new ECU and make sure you do not have a previous map loaded. 
  • Copy and paste each table axis by selecting all the values in a given axis in the old ECU and selecting Ctrl-C to copy the values to the clipboard. Select the same table (and axis) in the new ECU and select Ctrl-V to paste the values to the new ECU. Repeat for the additional axes, if applicable. 
  • In the new ECU, the modified table will appear in a bold font. When you've finished copying, double check all these tables to make sure the calibration looks good.
    • You can also copy table data to a spreadsheet and copy the values from the spreadsheet to Accesstuner as an alternate method
