mbFAST BMW 640i F06 ECU tuning + bubbling 55 hp more!

Thanks for your help.

This time we received a request for ECU tuning and bubbling for a BMW F06 640i!

Stock specs are 3L turbo 320hp. This 640i has 130,000 km and is a little bit over-marketed, so we reduced the power a little bit and increased it by about 55 hp with our mbFAST ECU Tuning. The customer was able to feel the difference. Also, since there is a metal catalyst in the car, we have installed a strong bubbling system.

I can write from OBD, but I had to use a different tool than usual and it takes a long time, so I accessed the ECU directly. In case you're wondering, OBD takes 40 minutes, ECU direct takes about two minutes. Well, the ECU has to reach out to see it, so it takes longer there, lol.

How would you like to try it? If you would like to try it, please contact us! Best regards.
