Hey guys, i logged my wgdc and it is always at 50% while cruising… and if i go wot it goes high to 60% and after 3k rpm it goes to 20-35% until redline, boost target fully reached. but why is it this high while cruising?
i just did it with stage 0, normally i drive 1 or 1+

the problem is that i dont have exhaust burble for example at 3k rpms, its so quite… when im at 1.5rpm i hear them rlly good

it's normal, I did a bunch of logs on stock map (& probably the same for most maps) for MOT/emission test reason and at cruising or idle (low load), it stays around 50%/60%. On low load it's a not a problem to have 60%, the throttle plate (throttle position on logs) is barely open.

They keep it on this position for fast reaction (be on boost rapidly).

Throttle position is barely open when you are cruising, then when you WOT, throttle position wide open (81 is the max value), and DME sets WGDC targets during spool (up to 70 on your log) then once boost/load target is reached, it sets WGDC needed to keep boost on target through RPM. On stage 0 it's normal to have low WDGC, it only asks for 7 psi.

To reply your question, WGDC are high (50-60) while cruising to have them always a bit spooled and let them react fast when you need them. However, for stage 0, the WGDC decreases as throttle position opens. Imagine if it kepts WGDC at 50 and you will overboost very quickly.

50-60 during WOT is more like for Stage 2+.

ok thank u ! now i understand but why my car doesnt burble anymore at 2500-4000rpms? and is 70wgdc on stage 0 high? it is just for a second but really high for me

No it's normal to be high on WOT (70-80-90 and even sometimes 100 depending on tune) just during spool (from 0 psi to reach target). It's just the DME trying to reach boost target as quick as possible, once reached it settles to a maintaining value.

Concerning burbles, I don't know, you mean your doesn't burble anymore between 2500 to 4000 with the burble option ticked on stage 0 ? but works on stage 1/1+ ?
