The second log looks a bit better, AFR isn't tanking and trims aren't maxed out, fp_h is where it should be.

Boost is still quite a bit under target, the fact it starts dropping after 4.4k rpm makes me think there's still a leak somewhere, maybe a loose coupler.

Just to confirm you are running the JB4 single turbo firmware AND The single turbo tune that you flash through MHD, right?

You need to go into the settings on the JB4 and change the TMAP setting to 3.5bar, otherwise it won't work. This is separate from setting what map the JB4 is running.

Given the age of the car I'd highly consider replacing the HPFP and perhaps the injectors. BMW did put out a recall for both, you might be able to get the dealer to replace them for free.

Great, I'm glad the leak was located.

Do you have a page that looks like below? TMAP setting should be in the User Adjustment section.

What manifold did you use, was is built, and curious to see were the wastegate is placed. Torgus isn’t correct on all his statements. Fix those hardware issues!

Make sure 3.5 bar map sensor is ONLY selected on JB4 and NOT on MHD!

im 99% sure that doesn’t matter. If you look at the BEF map Terry already has it set up as if you did click that. At least last time I looked on the e85 BEF it was like that.

It will not hurt to ensure it is set up like this, when I ran the JB4 it was a topic of discussion and both BMS and MHD said it should not be selected in MHD but only through the JB4 since it is the last element in the control loop.
