Product Information

Dinan Stage 1 Performance Engine Software - BMW B46 Engine

Engine software on a turbocharged platform is far and away the most cost-effective upgrade to improving engine performance. Through optimization of control strategies and taking full advantage of the engine's capabilities, substantial power can be extracted without any additional modifications. For G chassis BMW's equipped with the B46 motor this translates into nearly 50 WHP & 50 lb-ft of torque on pump gas with the capability of even more when running higher octane race fuels.  With a 14-30% bump in power, depending on octane, the results are unmistakable… and enjoyable.  

While increases in power via ECU upgrades in the marketplace can come at a cost to the engine's durability, this is typically due to improper calibrations that are simply after one goal regardless of engine health - maximum power. Dinan's calibrations are safe and reliable without sacrificing long-term reliability or performance. Dinan performance engine software is so much more than just turning up the turbo boost after all. It is a fully re-tuned engine management program that maximizes power while keeping all the BMW factory safeguards in place. In most cases Dinan software engineers also implement their own additional safety precautions in order to guarantee flawless performance that may not have been needed with factory power levels/programming. Protecting your BMW, while giving the most performance, is the definition of "Performance Without Sacrifice". To do just that, drivetrain and engine components are analyzed for strength, and then the calibration is tested on the dyno and in the real world for durability and drivability. This process has been a cornerstone of Dinan software development for decades and a major reason why Dinan performance tunes are often labeled as being the smoothest, factory-like solution in the marketplace. 

 

Dinan's ECU upgrades are offered in numerous configurations depending on your specific needs, desires or limitations. Whether you are limited to 91 pump gas, want to experience maximum performance with 104 octane, or something in between, chances are Dinan has an option for you. At its core Dinan offers 2 base options; Stage 1 and Dinan +. The Dinan Stage 1 Performance Engine Software is designed for the B46 engine to yield maximum power (for a variety of different octanes), improve drivability, and remove the factory speed governor for unadulterated entertainment. The Dinan + variant of software offers these same features (albeit limited to 91/93 octane) but also carries the signature Dinan 4yr / 50k, factory matching new car warranty that the brand is synonymous with.

 

Features:

  • More Power: Max gains of 44 WHP / 47 lb-ft of torque over stock on 93 octane with more on tap when using race fuels. Consult the performance charts for additional octanes and data.
  • Dinan Stage 1 performance software includes a limited lifetime warranty against defects in the software and provides free updates and reflashes as they become available. Labor or shipping charges are not included in the warranty.
  • Choice of numerous octane calibrations depending on your needs (91, 93, 100 and 104).
  • No required parts. Install on a stock car and receive the full power gains.
  • Full map rescaling for drivability from idle to wide open throttle and everywhere in between.
  • Optimized boost control, cam phasing, lamda targeting, fueling, airflow and temperature controls for maximum power output that is also safe and reliable.
  • Retains all BMW factory engine safeguards and adds numerous additional safety protections.
  • Top speed governor (VMAX) removed.
  • Torque by gear strategies implemented for maximum power output and traction.
  • Sport mode cooling that targets lower coolant temperatures added for optimum track effectiveness.
  • Pedal feel improved to naturally align with the increased torque output.
  • Sport gauges rescaled to reflect higher than stock power output.
  • Sport mode exhaust flaps that default to open.
  • “der Schubblubbern” (AKA Thrust Bubbles or Pops & Bangs) timer extended in Sport mode for additional audible satisfaction.
  • Remote start functionality (if equipped) completely retained. Digital key presence not required.

DME UNLOCK & FLASH NOTICE / HOW TO PURCHASE

 

2020 MY and prior (specifically up to a 06/2020 build date) B46 DME's must be unlocked and bench flashed by Dinan. 2021 MY vehicles are not supported at this time. While dealer / retail unlock and flashing tools are in development and will be available in the future, at present, two options are available:

 

OPTION 1: Visit a Dinan Dealer and purchase the Dinan Flash Software . They will remove and mail the DME to Dinan. We'll unlock the DME, flash the software and ship it back. They'll reinstall the DME.

 

OPTION 2: Purchase the tune. Send us your DME. We’ll unlock it, install Dinan software, and ship it back. The unlock process is free. Ground shipping to the continental USA is free. Follow the steps below if this is the course you wish to pursue.

 

Purchase the tune by contacting Dinan via phone at 1-800-341-5480.

Fill out the unlock form and select BMW under the unlock type.

Mail your DME to Dinan, 4800 U.S. Hwy 280 W, Opelika, AL 36801, USA, and include the last 7 of your VIN on the outside of the box along with a copy of the unlock form inside the box.

 

At no time during the unlocking process is the DME opened or physically modified. Once unlocked the DME can be flashed through normal dealer tools. If the DME is flashed back to stock, it will need to be unlocked again. Also, vehicle manufacturers issue many DME part numbers and revisions throughout their vehicle lineup. As such, some DMEs may be temporarily unavailable as new parts and/or revisions are released.
