The S58 motor, even early in its production life, is known as an immensely capable engine delivering power well beyond its advertised levels. This is typical of most modern-day BMW M platforms. What is not typical however is the copious amounts of headroom left on the table for entities like Dinan to take advantage of. Approaching, and/or exceeding, maximum gains of 100 WHP/TQ with pump gas and no additional modifications for an inline-6 is a dream that has become a reality. 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 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 S58 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 137 WHP / 149 lb-ft of torque over stock on Competition models with E85. 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, 104 & E85).
  • 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.
  • Improved 0-60 and 1/4 mile times.

Dinan Stage 1 Performance Charts

Engine & OctaneSelect Graph Type

Looking for non-competition data? In its base configuration the ONLY calibration difference from the competition models is an artificial reduction of power of ~20 WHP from ~5500 RPM and above. As such you can use the competition data above almost entirely but reduce the stock curves from 5500 RPM and above that amount. The result is larger gains over stock at the extreme top end of the power curve for base S58 owners (albeit the same end result).

Calibration Quick Reference

All info supplied in the table below is 'at the crank' for consistency when comparing data with BMW advertised numbers which are always reported at the crank. For data 'at the wheels' please refer to the appropriate chart from the dropdowns above.


Table also represents all possible ECU software options currently available for the selected platform. Some stages / variants may require additional hard parts to achieve advertised numbers. Please consult the appropriate stages product page for details.

DME UNLOCK & FLASH NOTICE / HOW TO PURCHASE


2020 MY (specifically up to a 06/2020 build date) S58 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. Weโ€™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.


  1. Purchase the tune by contacting Dinan via phone at 1-800-341-5480.
  2. Fill out the unlock form and select BMW under the unlock type.
  3. 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.


CODE CLEARING: Customers doing the DME removal/install process themselves should be aware that in the case a fault code occurs, having the ability to read and erase fault codes is crucial. Failure to be able to perform this task may result in a vehicle that is inoperable. Dinan will not cover any expenses related to not being able to clear codes (towing, equipment rental, etc.).

COMPATIBILITY NOTICE


BOX CODES: The S58 engine and its multitude of variants account for numerous unique box codes across various platforms. While Dinan has created files for many of these permutations, there is a chance you may have a box code that we have not seen. If this happens to be the case we will need to create a file for your vehicle. This process could add up to 7 days to the bench flash process although in most cases it will be turned around within 2 business days.
