S63TU JB4 + backend flash
 

Hi everyone. I have a 14' M6 runing a stage 2 BM3 tune and had a great experience running JB4 on previous cars. Love the features the JB4 gives and the ability to data log and have the monitors so easily. So i was wondering if anybody here is running it with a backend flash and how do they like it (compared to BM3 or other tunes)? If so who's done the backend flash for you?

Thank you for any ideas!

The JB4 is a great fine tuning tool for flashed cars, useful for on the fly boost changes, boost by gear, easy logging to your phone, addl safety systems, etc.

Yes, that's why I love it and my experience with it on the N54 platform was amazing. I just wanna know more about the backend flashes as you don't offer that for the S63tu like the N54. Who should I go for to get the backend flash? I know from a few guys that jb4 alone on the s63tu tends to max out the trims quick because of the fuel system.

Any advice?

JB4 works well with stock or flashed ecu.
DME, MHD, BM3, SMS, etc ...

Oh ok. I guess its not like the N54 where you had to have a backend flash to run the JB4 too..
