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.

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.
