Mission Performance: New to forums, not new to the industry

You guys might not have heard much about us in the past due to the fact that we have never been active on forums but its time for us to join in and provide BMW world with much needed tuning/reflash support. We have spent many years in BMW industry behind the scenes, building many unique and fun projects. Our involvement with BMWs has began with E39 chassis for which we built a twin-screw supercharger setup for the 540i. Since than we have progressed to building few S62 E39 tourings (once of those was featured at recent BimmerFest). Since then, we have moved on to Fxx chassis and performed word's first successful conversion of RWD 328D F31 touring and currently entertaining an idea of building a S55 (or even N63tu) powered F31.

Well, enough of past projects and time to say why we are here now. While working on the projects in the past, we noticed that BMW performance tuning world is dominated by few old-timer companies delivering very similar product. Those companies for sure have earned your trust since they have been around for a long time, but because of their long-term involvement in this industry, they don't have desire nor need to building new solutions and ideas. This is where we come into play. Making extra power on the new Fxx platform is no brainier and even an amateur tuner can get some gains, but what sets us apart from everyone is a concern for longevity, safety and innovation.

We have seen impressive power gains on S63 and S55 platforms in the past using custom software re-flashes and tuning boxes. Being around high powered engines for a while has taught us one thing: A proper engine calibration software is the only option when it comes to reliability. Since Fxx chassis is a relatively easy platform to make decent power on, few companies decided to do what Japanese imports have been doing for many years, and that is using tuning boxes to trick signals to the ECU. Tricking a computer of $60k+ car using a $300 tuning box just doesn't seem right to us. Companies can state that the tuning boxes are 100% safe, but that is just not true. What is true is that for optimal reliability and drive-ability, a proper designed software calibration is the only right choice and no one can deny that. Since this is a given fact, then why do a lot of high powered Fxx still use tuning boxes? Well the answer is really simple: most tuners are satisfied with their profits and just do not feel the need to spend time and money into further research and development. This leaves tuning support half finished for general public and completely unacceptable for those individuals that push their engines to the limits.

Tuning boxes have 2 advantages over a software re-flashes: A) ability to use higher rated MAP sensors B) Ability to implement meth injection. MAP sensor limits have shown to be a huge issues when it comes to proper calibration and we have seen that with quite a few cars tuned by few USA and abroad companies. We have witnessed medium powered S63s and N63tus hitting the MAP limits at 4-5K rpm. And then what? How can you build and sell a performance tune that is already maxing out your sensor at mid-rpms. Well, in our opinion you can't do that and this is why we have never offered for sale our software re-flashes until we figured out the solution to this problem. Our solution is a custom software calibration for a 3 and 3.5 bar MAP sensors paired with a plug and play sensor that we are rolling out within next month. This makes us the only tuner in the industry (until the point when others copy our re-flash) to be able to safely pass the 2.5 and 3bar limits and offer a reliable and well calibrated software for all of our customers that go with stage 2+ packages.

We believe that when a customer purchases a re-flash for their cars, every function should work as intended. At this moment, no other tuner has been able to properly re-flash S63 or N63tu, calibrating the Sports Display to show the actual torque and HP numbers. It might seem like a small deal to some, but to us this is a major concern. Sport display receives the proper data from internal torque model. If the sport display is saying you are making a "stock" amount of torque while dyno is showing 15% increase, well then we know something is wrong with a tune and torque model. In addition to this, quite few computer functions depend on this torque model (including AC and charging system) and proper calibration is a Key to a long lasting platform. Yes it takes a lot of time and resources to properly build a tune, but this is what sets us apart. We do not rush development and release generic software but instead perfect everything and only then make it public.


Future plans for all of you high powered customers: We know that a lot of you chose tuning boxes as they allow you to run integrated methanol injection. Well, this is all about to end as we are starting development for factory-integrated methanol injection using a plug and play harness for BMW factory ECU. That means that we are building complete calibration and program from scratch for pretty much all Fxx vehicles that will allow us to do just this. This is something that has not been attempted before as the R&D costs are phenomenal but having in-house engineers makes it all possible for us.


OBD/End User Flashing: There has been a lot of talk over the last year of OBD flashing release, but no actual release date. That is because such support will not be possible anytime soon. Back in E90/E60 day, tuners got very lucky as their cars had backdoors to flashing function of processor that allowed for un-authorized software to be loaded onto a car. That has all changed with late production TC1796 and introduction of TC1797 processors. Since BMW switched to this new processor line, the backdoor has been closed and only factory signed software can be used on the vehicle. After many months of research of this system, we have been successful of flashing partial data over OBD. The partial data is better then nothing, but in the end of the day it is still not something that we can use. The only way to properly flash Fxx over OBD is to have the master RSA key for the bootloader. Its not possible to brute force crack this key (its possible but would take a very very long time) and it can not be extracted as computer only has public key, not the private "master" one. So at this point on, do not count on having OBD support any time soon. It might happen, but probably not any time soon. Without the backdoor, the only way this will happen is if someone wants to spend good money (and by that I mean very good money) and obtain the mater RSA key for boot loader encryption.

Due to this dilemma, we have been forced to abandon OBD flashing research and instead built our own M-Boot option. M-Boot was developed by Mission Peformance as an additional solution for all of our returning customers that either want to upgrade performance stage or "temporary" go back to stock for a dealer visit. Since M-Boot is a custom written bootloader for the Fxx chassis, there is no additional chip/hardware needed to be added to the ECU. In addition of having the ability of re-flashing the computer without sending it into our offices, M-Boot offers one very unique feature that no other company can offer at this point. After installation of M-Boot, your engine computer will never need to be updated at the dealer. That means that to the dealership, your engine computer will always show as up-to-date, factory original and in most cases, your tuned computer will not get reflashed to factory state. If for some reason dealership over-writes our M-Boot, we will reinstall the previous calibration for free.

On-Site flashing for Group Buys: We understand that to many customers, sending in your computer might not be an ideal solution. For those individuals, we are doing something that no other companies are offering as well. We can set up group buys of 10+ customers and I can personally fly out and flash your computers. Of course a working environment has to be setup for this to happen, but interested parties can contact us directly to set this up.



As a bonus, we are offering performance hardware ,such as downpipes, for many Fxx vehicles. Over time we will be adding more product to our website but if you have some special requests, just shoot us an email at sales@missiontuning.com


And questions or requests? Just send us an email or post it here. We are always open to suggestions and requests.
