Engine tuning (DME/ECU/ECM Tuning) for the BMW F90 M5 typically involves modifying the engine management software, also known as "flashing" the ECU. This process can increase horsepower and torque, improve throttle response, and also change the shift points of the transmission. Some popular engine tuning options include: Software remaps: A remap of the engine management software can increase the power output of the engine by adjusting the fuel and ignition maps. This can result in significant gains in horsepower and torque. Downpipes and catless exhaust systems: These modifications can improve exhaust flow and reduce backpressure, which can result in additional horsepower and torque gains. They also give the car a more sporty exhaust note. Cold air intake systems: Replacing the factory air intake with a high-flow aftermarket system can increase the amount of air that the engine can take in, resulting in more power. Intercoolers: Upgrading the intercooler can help to reduce the temperature of the incoming air charge, which can result in more power and improved consistency. It is important to note that any engine modifications should be done by a professional and it's also important to make sure that the tuning is done correctly as it can cause damage to the engine if not done correctly. Additionally, some modifications may void the factory warranty, so it is always important to consult with a professional before making any changes to the vehicle.

The performance enhancement for your 2021 BMW M5 is remarkable, generating an increase of up to 150 WHP compared to the stock configuration, all while utilizing the factory engine.

Furthermore, our BMW M5 Tune boasts the potential for a substantial power surge of up to 300 WHP beyond the stock levels, particularly when employed with a forged engine.

Our tuning solutions have undergone rigorous testing across diverse locales, encompassing dyno assessments, real-world road scenarios, and even track trials on a global scale.

Thanks to our meticulous software development process, our tunes are universally regarded as entirely secure, provided that the appropriate octane rating is utilized, irrespective of geographical location.

These fully functional and meticulously crafted tunes mirror the OEM characteristics and can be customized upon request. To address common queries, we've compiled a list of frequently asked questions:

Frequently Asked Questions:

  1. Is it possible to tune a 2021 M5? Yes, tuning options are indeed available for the BMW M5. The lineup offers several choices for tuning enhancements.

  2. Can a 2021 BMW M5 operate on E30 fuel? Absolutely, our Stage 1 and Stage 2 tunes for the 2021 BMW M5 are engineered to operate safely on E30 fuel, with a maximum ethanol content of 30%.

  3. Can a 2021 BMW M5 utilize E85 fuel? Indeed, our Stage 2 E85 tune for the 2021 BMW M5 is meticulously calibrated for ethanol content ranging from 60% to 85%.

  4. What is the typical horsepower output of the 2021 BMW M5 F90? Ordinarily, an unmodified BMW M5 F90 records around 550 WHP on a dynojet. Our tuning can often propel this figure to a substantial 700 WHP.

  5. Is a Bootmod3 or MHD License necessary for the 2021 BMW M5 Tune? No, our 2021 BMW M5 Tune installation doesn't necessitate a Bootmod3 or MHD License. All pertinent files can be seamlessly exchanged via our dedicated support portal.

  8. Is it advisable to apply a tune to the 2021 BMW M5? Absolutely. While some concerns regarding risks might exist, it's important to acknowledge that BMW often conservatively tunes their vehicles, leaving substantial untapped power. Our calibration engineering team has invested extensive effort to develop entirely secure and stress-free calibrations, allowing access to a portion or the entirety of this latent power. Remember, in the realm of ensuring safety, a conservative approach is often the wisest choice.

Fastest car I’ve ever had

I tuned my BMW M8 with ECM and let me tell you it’s the fastest car I’ve ever had, I have been tuned for a while and not a single issue.

Hands down the wildest Tune for F90

Heard about ECM tuner from another client that had a very fast F90 M5, his car was putting 9.8 seconds 1/4 mile all day long. I am happy to say i switched from my previous tuner and not myself run 9.9. Thank you ECM
