Dinan Performance Engine Software Flash

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, immense power can be extracted without any additional modifications. The newest BMW’s powered by the latest B58 powerplant is no exception to this. In fact, supporting factory systems make the latest variant much more capable from the start compared to the engines previous iteration. 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 labelled 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 on E85, 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 B58 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.

Benefits of the Dinan Performance Engine Software for the BMW B58(O1) Engine:

  • More Power.
    – Dinan Stage 1: Max gains of 116 WHP / 136 lb-ft of torque over stock on E85. Consult the product page for performance charts for additional octanes.
    – Dinan +: Max gains of  43 WHP / 62 lb-ft of torque over stock on 91 octane.
  • Warranty options to fit individualized need. Visit the Dinan website for full warranty details on either option.
    – 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.
    – Dinan + performance software matches the factory new car warranty (4year / 50,000 mi) and is the warranty protection commonly associated with the Dinan brand.
  • Access to numerous octane calibrations (91, 93, 100, 104 and E85) depending on your needs and/or variant of tune (Stage 1 or +). Switching between mappings would require a reflash at a Dinan authorized dealer.
  • 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, lambda 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.

DME UNLOCK & FLASH:  2020 MY and prior (specifically up to a 06/2020 build date) B58(O1) DME’s must be unlocked and bench flashed by Dinan. 2021 MY vehicles are not supported at this time. You have the option to either send in your DME to Dinan directly or to have your local dealer perform the DME removal and send in to Dinan. Details for both processes can be found on Dinan’s website.
