Default Flash Tune B58 Logs - 08-22-2018, 08:52 AM
Hello, I have the Stage 2 Mission Performance flash on my 340i.

Im having quick hesitations around 5.5k rpm, so I took some logs which are attached.

I believe Run1 captured the issue, but I am far from fully understanding all of this so it would be great if someone would take a look

Any one have any ideas of what could be the issue? I am on my second flash from them. Initial flash was way worse, as this revision map feels much better, but not perfect. Thanks!!

Mods in sig... running 10 gal of 93 + 2.5 gal of e85.

Nice to see some flash logs, curious what the experts have to say!

Besides the hesitation, how Does the car feel? Did you have a jb4 before the flash?

These are not jb4 logs, but I can view them on my iPhone.

Is that 21-22 psi? No problems with fuel?

No they arent jb4 logs. They dont have to be for support do they?

Yes that is the boost pressure that the logs show, but not sure if fueling or what is my issue. The whole fueling cap in the software thing is gone though, as this much boost would be impossible without meth.

Not going to get any advice around here unless they are JB4 logs.
