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.

This is a CUSTOM TUNE and NOT an Off The Shelf (OTS) map. NO REFUNDS will be given due to length of time of the tuning process (OR FOR ANY OTHER REASON) and there shall be NO expectations of how many revisions will be needed to finish the custom tune.

Ethanol Maps Require 0.22 Spark plug gap we usually use NGK 97506

TUNING METHODS:

OBD Tune

OBD tunes allow customers to simply plug and upgrade their ECU. We will ship you a ECM Tuner cable and email you instructions on how to install it, it must be returned after the tune flash is complete.

Bench Flash

Requires ECU to be mailed in. This upgrade requires you to send us your ECU for re-programming. Includes are free obd2 unlock if you plan to flash with bm3 and use our custom map.

Frequently Asked Questions:

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.
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%.
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%.
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.
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. However, Bootmod3 and MHD licenses are extremely valuable for data logging purposes to fine-tune your vehicle's performance.
Do you offer a Burble Tune for the 2021 BMW F90 M5? Certainly, upon request, we provide the sought-after Burbles or "Pop & Bang" settings. Typically, burble tunes are designed for Stage 2 vehicles equipped with modifications.
Is Flex Fuel compatibility available for the 2021 BMW M5 Tune? Regrettably, genuine Flex Fuel integration is not attainable for V8 BMW engines. Nonetheless, our tunes are meticulously calibrated to accommodate a range of ethanol content between 15% and 20%, and we possess the capability to calibrate for various ethanol levels, excluding Flex Fuel.
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.
