Details

We are proud to announce an early release of performance flash tune for the G20 M340i. Our reflash was designed and meticulously perfected by in-house experts to deliver impressive gains with minimal expenses. Extensive improvements were performed to the software in order to provide significantly improved performance, great efficiency and unparalleled reliability.

-Flashable over OBD2 port with no need of DME removal.**

-DME Tampering Shadow code disable

-Optimized Boost Control

-Optimized Valve Lift and Timing Control

-Extensively modified knock control to ensure reliability and safety

-Cold start and VMAX delete (Optional) 

-Burble

and much more

As with any modification that significantyly raises the output of the engine, we highly recommend having spark plugs properly gapped. Suggested gap for Stage 1 and Stage 2 flash is 0.025".

 

*M-Boot:  M-Boot was developed by Mission Performance as an additional solution for all of our 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, there is no additional chip/hardware needed to be added to the ECU. In addition of having the ability of  reflashing the computer without sending it into our offices, M-Boot offers great features as CVN and Calibration ID spoofing. 

 

** All Pre-July updated vehicles can be flashed over OBD2 port without a need to send the computer to us. If the vehicle is flashing with the Post-July update, then DME will have to be sent to us. DME will not be opened or cracked, but instead it will be flashed using mflasher on the bench.
