Your duty cycle settings are messed up. Its preventing your wastegate from closing enough to build boost.

Set your WG duty cycle setting to 50 across the board and re log.

how can I set into map 2/5?
I only have jb4 mobile apply

Go into settings. Go to advanced. Go into the user adjustment menu. Set all the duty bias values to 50. Press save.

ok thanks, i will try it next time

user adjustment it's not only for map6?

The boost settings in the user adjustment menu is for map 6 only, but everything else is carried across all maps.

I try as you tell me with 50 on duty bias on map 5
the last 4 run I put 60 since 5000tr

Looks like.your hitting boost a little better. Id raise your FF up to 80 to speed up the wg learning and you should be good.

What fuel are you running?

Looks like traction or clutch/trans is an issue for you?

hi everyone

I have do some run on map 6 just for fun can someone tell me if everything it's ok and help me for the setting

Steve @ BMS/Fuel-It! 06-01-2021 11:06 AM

You're maxing out your turbo...not much more you can get out of it. Timing is a bit wonky, I'd recommend updating your firmware and sticking with one of the standard maps unless you have a particular reason to run map 6 as it looks to me like you have entered unrealistic boost targets.
