Usually for people running larger turbos. Not needed for stock turbos.

You're not over boosting on the shift here? The shift reduction is used when you have the EWG connector, and then a default value of 60, reduces WGDC during shifts, to prevent over boosting in the next gear.

You can change it to 60, yes. It's not a setting that is generally relevant unless you're running a really aggressive boost profile and are over boosting post shift. Are you? If you are not then don't worry about it. If you are then post a log of that and I can help you refine the setting.

Use boost 20-22 psi.

update 12 version, tests.

Adaptations?
The car is inadequate.
B48

Version 12.

The first log is 6 map, target is null.
The second log - 3 map, 100% pedal - kick and sharp brake (after which I let go of the pedal).

Update: map1 - error (check engine), attachment.

If I activate WMI on all maps, will it use the additive set point or function as simple on/off according to window/rpm and boost activation set points? I'm considering using map 5 with WMI, but I'm not sure if additive amount is active in such an application. Please let me know... Thanks.

I have run Map 5 with WMI by setting Trigger mode to 1 and it felt pretty good. I think meth additive is only active on map 7, and Map 5 is a fixed +6 additive? The additional meth fueling helps that map though if your octane sucks.
Someone from BMS can confirm for sure but it does work.

Why are you considering switching to 5? You had such great results on 7...

It's getting to 100+ again and DME starts wabbling. I never tried just Map 5 and WMI. When I did it the other day, the car was much better and consistent. I'm anxiously waiting for final BEF+JB4 maps to be worked out. I'll go that way as soon as they are. This is just an interim fix. Lol.
