B58 flash tuning details in the next few days! - N54Tech.com - Your Source for International Turbo BMW Racing Discussion

This is extremely good news. This is the same ECU our B9's use and there's already been flashes rolled out to the BMW's... only a matter of time.

That is good news, but based on initial results with the JB4 there wont be anything major on the S5 without some hardware changes. The JB4 is thermally maxed at 2-3psi boost increase.

interesting that's the first news I've heard about the jb4 on the b9 v6 turbo. I've been waiting patiently to find out the potential... care to share anything more?

​​​​​​I have a build thread where I'll post updates. Haven't gotten to do any test sessions due to busy work schedule. It's been working great though and the car is strong with it at +3psi

I want to go back to that original linked thread and ask "how long is a few days, exactly", but I'm not going to register just to ask for an update. Seems like there was about to be some big announcement, and then "poof".
