The same concepts apply, but not exactly. On the B58 the larger issue is the moving DME BT due to internal fuel limiters, so it's not practical to fully nail down boost targeting via duty bias tuning. Just get it in the ball park.

Thanks,

EWG applications are "integrated" boost control, meaning the DME is still doing the majority of the control with the JB4 only adding or subtracting from that slightly to keep boost on target. As such the logs will look nothing like the PWG ISO logs you see in the thread.

Duty bias tuning can still be done on EWG vehicles but generally only to set the proper shape of the profile. In most EWG cases the default 50 across the board settings are suggested.
