The Quick and Dirty (Features and Benefits):

  • More Power: Stage 1: Max gains ranging from 122-130 WHP / 190-198 lb-ft of torque over stock with 93 octane. Consult the performance charts for additional octanes and/or detailed data on specific vehicle variants. Dinan +: 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.
  • Warranty: 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.
  • Stage 1 affords access to numerous octane calibrations depending on your needs (91, 93, 100 and 104). Switching between mappings would require a reflash at a Dinan authorized dealer. Dinan + is limited to a single map (91).
  • 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.

The Story:

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 +130 WHP and +200 lb-ft of torque courtesy of Dinan Stage 1 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. One that will be sure to result in a very enthusiastic grin. Utilize race gas and the gains jump yet another factor of fun with the Stage 1 calibration or opt for peace of mind with a factory matching 4yr/50k new car warranty with Dinan +. Both offer performance value propositions that are 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.

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 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 S63TU4 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 octane) but also carries the signature Dinan 4yr / 50k, factory matching new car warranty that the brand is synonymous with.
