The boost taper is because if you shift in a auto it builds boost so if you run the same psi all the way to redline, you’ll be over the target on the next gear after shifting
Watched the video, but am still a bit confused. My WGDC in the log BEFORE going WOT is at about 98%. Once WOT, it goes shortly to 100% and falls down to 84-86% throughout the pull. What should all of that tell me!? Is 100% closed or how should that be interpreted!? I believe the interpretation of wgdc is not very clear from the video, focus is on troubleshooting instead.
What I am really saying is that without reference values for different setups and loads, the WGDC value is not particularly useful, except for comparison. But anyway - thanks for another informative video!
@@Y.D.43210 I can't even give that because it'll vary based on environmental conditions and setups. That's why I said you'd need to figure out the appropriate ones with your guner.
On my E82 N55 I am only making about half of boost target at WOT according to my MHD logs. The target is 10.9 and it is making 4.9 and the highest boost I have seen is about 6PSI The car has VRSF intercooler and charge pipes. It would seem to me that if I had a boost leak the WGDC would be near 100% but I am seeing about 45%. Am I over simplifying it or can you use WGDC as an indication of boost leak? .
My 340 on MhD stage 2, OTS E40 has the waste gate get up to 96-98% without hitting the Boost target…. Currently getting revisions from MHD, but I’m confused on what it could be, I’m steadily making 18-19PSI but I know the WGDC should be mid 80% with my setup, anything????
Yo what up Kern. Just wondering are we looking at the WGDC 1 (%) number? I have a pull in 3rd gear and that number is no lower than 78 and hits 100 for a bit but mostly around 90s. Would that tell me my turbo is working really hard and I need to upgrade the air flow? This is on a stage 2+ 91 map.
im running n55 GC+ and my WGDC is wide open wont shut. I took the dp off to check the turbo and everything is good. I smoked tested. No LEAKS... Changed out Boost selonoid. .. any tips

I love your videos because although you’re tailored towards the b58 platform. I can still apply the knowledge to any other engine modify. #n55
You earned a sub from me sir
Great video! Keep 'em coming

Not really
Hi Kern. I have bimmerlink. How do I see my wastegate duty cycle?

Guess you didnt watch 3:09 🤨
Must not gave watched 2:52 either 🫣

It can be a lot of things in your case. A smoke test will confirm if there's a boost leak

IATs, DA, Altitude, etc all have an effect

If you hit boost target, I'll say it's ok.

is the wastegate bad
Mines around 80% throughout wot, is that good?
Sounds typical but it just depends
