2012-2014 VW Passat 2.0L TDI FlashZilla Tune File

Speed up engine-warm up with a 1,100 RPM (or another RPM of your choice) idle. The idle will return to stock state (approximately 830RPM) by 70C (158F) coolant temperature. Results may vary. Example Idle RPM vs. coolant temperature progress chart below: Most factory ECUs actually already has Dynamic Idle, especially at higher elevation or very cold temperatures. We typically do not set a higher idle RPM etc. than the maximum that's set by the factory. An engine that gets warmer sooner means that you get interior heat sooner (more comfort during cold weather) and reach optimal efficiency (fuel economy) sooner. If you want a permanently raised idle (e.g. 950-1000 RPM) to reduce vibrations, especially with a stiffer aftermarket engine mount, then we also can do that.

Increases glow plug strength and duration if it's cold enough. Improves cold starting performance (reduced chance of startup smoke and reduced engine stumbling).

This tune option is for people who want an aggressive Rev Limiter either in neutral or at the top of the rev range in Drive or Sport for DSG's and any gear for manuals while driving. It is mechanically hard on the vehicle and can be set to any custom RPM you prefer - We do not recommend exceeding 4600RPM - *We do not offer refunds for this tuning feature!*

Reflash your transmission using factory software after swapping to a manual transmission. ECU will need to be recoded separately using VCDS to complete the process, make note of the current transmission coding before you flash the ECU.

Pick the calibration that matches your fuel pump upgrade. Only one can be used. Only required if you swap to a CP3 fuel pump . This requires custom tuning work for best results. We will not add this to other brand tunes.

Every TuneZilla tune is flashed with the FlashZilla Pro and a Windows 10/11 laptop. Skip this if you already own one.
