Dinan + Performance Engine Software - BMW S63 (TU4) Engine
Product Details
Some of the world's most potent sedans and SUVs to begin with, the F90 M5 and F95 X5M now have the ability to go beyond formidable and to levels of outright domination in their respective classes. With max gains on pump gas nearing +115 WHP and +160 lb-ft of torque courtesy of Dinan + software the battle for runner-up in each respective class is the only question. Those are garish gains on their own but considering that those figures are with no additional modifications or alterations to the catalysts, it's an even more impressive feat. Going one step beyond simply power and including a factory matching new car 4yr/50k warranty you get a performance value proposition that is hard to fathom. While increases in power at this scale typically 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.

Features:

  • More Power: Max gains ranging from 96-104 WHP / 148-157 lb-ft of torque over stock with 91 octane. Consult the performance charts for detailed data on specific vehicle variants.
  • Dinan + performance software matches the factory new car warranty (4year / 50,000 mi) and is the warranty protection commonly associated with the Dinan brand.
  • 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.
  • Remote start functionality (if equipped) completely retained. Digital key presence not required.

Compatability limited to 2020 MY and prior (specifically up to a 06/2020 build date). 2021+ MY not supported at this time. See DME unlock and compatibility notices at the bottom of the product page for information on additional potential installation/compatibility limitations.

DME UNLOCK & FLASH NOTICE / HOW TO PURCHASE

2020 MY and prior (specifically up to a 06/2020 build date) S63(TU4) 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, at present, we must remove your ECU and send it to Dinan. Please contact us for more details.

At no time during the unlocking process are the DME's opened or physically modified. Once unlocked the DME's can be flashed through normal dealer tools. If the DME's are 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 S63 engine accounts 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.
