The BMW X4 M40i ECU flash is the best modification you can do to this performance SUV. With the 3.0L turbocharged engine, there is tons of room for more horsepower and torque while still being efficient.  Coming stock with 360PS (355hp), our Stage 2 horsepower gain takes you over 415 horsepower! Huge power is lying in wake and VR Tuned can help open that up! Tuning the vehicles fuel, timing, and boost pressures are just some of the ways we make reliable and efficient horsepower.

What are the benefits of VR Tuned?

• #1 priority is our customer service to you!
• Our tuning is used worldwide. We have powered vehicles of all types.
• All ECU tunes can be reverted back to stock if necessary.
• With the VR Tuned ECU Flash, basic bolt-on performance parts will not require a retune of your ECU.
• Adding parts such as an exhaust, intake, plenum, pulley, will all adjust with the tune.
• If you add higher octane fuel, the ECU will adjust accordingly.
• We can tune cars worldwide including JDM, EU, Australian, and USA cars for different types of octane or environments.
• Other custom enhancements are available if requested and applicable.
• We test and dyno tune on our own cars to make sure what you get is safe, reliable, and gives you the results you want!

How to Flash Your ECU?

• Use the Alientech Powergate 3+ handheld device. This device is a touchscreen module that lets you store your original and tuned files to easily flash between them. See Instructions Here.
• We can bench flash the ECU. To bench flash the ECU, you must remove it from your vehicle and send it to us. Once we receive the ECU, we will prepare the tune file and then send it back to you for reinstallation.
• Bring your vehicle to our facility where we can use our Master Cable to flash your vehicle.

Options:

• You can select to get both Stages of our Tune.  The Stage 2 is usually for those looking to maximize the performance of their vehicle.  Though not required unless stated, this is usually for those running a performance exhaust and at least 91-93 octane fuel. Can only be done if OBDII flashing is available.
• For this ECU Flash, we also offer the following features that are optional and can be selected:
• Pops and Bang Burble Tune
• Cold Start Delete
• Speed Limiter Raised - VMax
• Sports Display Enhanced - We increase the HP and NM or TQ number on the BMW Sports Display. For example if your car says 350HP Max, we can change this to 400HP.
• Some features not listed can be requested during the File Upload process

For reference this ECU is a Bosch DME__860.
