2021+ BMW M3/M4 Competition Gets Power Boost Almost As Big As Its Grill!

The new BMW G80 M3/G84 M4 has definitely disrupted the car enthusiast community with its updated front design, increasing the size of the grill as many of us expected. Whether you love it or hate it, the newer power numbers, technology, and styling are here to stay. Since the G80 is such a new car, the race to being the first in the aftermarket G80 industry has begun…and quick. While companies are researching and developing new parts to increase horsepower, torque and enhance throttle response there’s one major problem, warranties. 

Most people are riding the tough decision to satisfy their desire to modify their brand new M Performance cars or to keep the warranty in case anything goes wrong. No one wants to void a warranty with a mod, then have something major go wrong with their brand new car and be denied warranty work at the dealer. With this being said, there are not many performance mods that are available to you. Unless of course, you’re willing to risk it. Although, what if there was an easy performance mod that you could gain some extra horsepower and torque without ever voiding any warranties? 

Most people would think of tuning, as there isn’t much physical evidence of a tune being installed without a serious dive into the car. You’re on the right track, however, manufacturers are making it increasingly difficult to tune an ECU without evidence of tampering. They do this by blocking tuning being done via the ODBII port. “Why can’t I just remove the ECU and tune it on a bench?” While you can, these ECUs are sometimes in boxes that have specialized seals, making them difficult to remove without leaving clear evidence of tampering. Once at the dealer, they can deny you service upon seeing the damaged seals. Of course, this doesn’t go for all makes and models, but what if it does for YOUR ECU?

We have spent extensive time thinking about this issue, and how we can resolve it. We’re proud to say that we have come up with a solution that ticks all the important boxes. Our ECU Tuning Box Kit V2 for the BMW M3/M4 Competition is the all-in-one solution to this problem. It acts as a middle man between the air system and the ECU. It tricks the ECU into sending more boost than the engine actually needs, therefore providing more power and torque. Of course, this is an oversimplified explanation but you get the point. The ECU Tuning Box Kit V2 for the BMW M3/M4 Competition is a complete plug-and-play system. This makes the box so easy to install, that all you have to do is connect a wiring harness (included with your purchase), and stick it anywhere inside your engine bay. The tuning box internals are enclosed in a water-tight casing, making sure that it won’t get damaged due to any stress you put it through.

Now of course, in order to protect the engine from overdoing itself, we have included safety measures to ensure nothing goes south. Our biggest safety measure is a togglable temperature system that will only apply the performance tune when the engine hits operating temperatures. You can adjust and configure the temperature settings via the optional mobile app. Speaking of the mobile app, we also have an additional option to control the tuning box straight from your IOS or Android devices. Installing this app on your device makes the box completely hands-free, giving you the ability to even change modes on the fly. Did we forget to mention the performance modes? The box comes preinstalled with seven different power levels for you to choose from that will dictate just how much extra power you want at any given time.  You can easily switch between modes via the app mentioned above, or by using the + and – buttons directly on the tuning box. Don’t like the box, or need to have some servicing done? Simply unplug the box from your vehicle, connect the old wiring and there’s no evidence of any tampering ever happening.

Finally, let’s talk power numbers. We ran a stock G80 M3 on our Mustang Dyno here at Vivid HQ and found that we got 503bhp, with 479ft/lbs of torque stock on 93 Octane fuel. We installed the tuning box, ran it again, and got 640bhp with 559ft/lbs of torque. That’s an insanely easy increase of 137bhp and 80ft/lbs of torque with JUST the ECU Tuning Box Kit V2 for the BMW M3/M4 Competition! With such an easy install, easy power gain, and all without voiding the warranty we can’t really see why anyone wouldn’t want one of these VR Tuned Performance boxes. Not only do we offer ECU Tuning Box Kits for the BMW G80/G84s, but many many more platforms as well.
