What is your WGDC driving around & at idol & why?

Those of you who have MHD can easily monitor this %.

I have ProTool monitoring. Worth it to get MHD monitoring to see this?

Idk.... you get MHD for 3 reasons

1) get MHD if you have a non-tuned 335i w/ OEM turbos. Basically, use their OTS maps

2) get MHD to work w/ JB4 BEF

3) get MHD to work with a BEF custom tune

WGDCs are pretty important parameters to monitor and log. If ProTool can't, MHD may be a worth while investment. Their monitoring/logging license is about 85 bucks.

Because I've noticed you use this "alternate" spelling frequently:

i·dol
/ˈīdl/
noun
an image or representation of a god used as an object of worship.

i·dle
/ˈīdl/
verb
(of an engine) run slowly while disconnected from a load or out of gear.

I've got Protool and MHD and am pretty sure the monitoring gauges are basic and nowhere near as good as MHD monitoring/logging.

My % is 50 just driving around & Idle.

I'm already tuned, but the question is do I pay the $85 to get another monitoring service that may or may not be the same as what I have.
I'd need to check protool but if it doesn't have it, is seeing my WGDC worth $85? Maybe, if it catches an issue.
I heard someone say ppl with aftmkt inlets can over boost because the turbos spool too quickly. Can anyone weigh in? True? Guess I could log and see.

I have inlets & outlets & I do not over boost

Does Protool let you do a proper Log with WGDC, HPFP, LPFP, Fuel trims, Boost target, mean, psi, AFR, all 6 cylinder timings etc?

If it doesn't, then getting MHD with monitoring package is well worth it.

I would venture to say, probably not.

I think it does 90% of those. I've looked for WGDC once and couldn't find it in the list, but it does everything else. I could give a full list tm. I thought besides WGDC and oil pressure, it was the same. And it does have a very easy logging function+auto log.

MW what are you trying to ultimately figure out, if your wastegates are open during idle?

I'll find out tomorrow for you when I get on the road..

Note from Per Wedge just to have:
Wastegate Duty Cycle
- The more open (higher %) the WG is the more boost the system is trying to build. The greater the % the more vacuum reaches the WG Actuators keeping them shut which builds more boost.
- It's important to note that with the N54 the vacuum keeps the actuators shut which is opposite of many other manufacturers where vacuum is used to open the wastegate(s)
- A healthy WGDC around is around 48-55 during a 3rd year pull

Can you tell me how I can log using Protool, I have it but haven't got a clue hkw to log using it.

Idk I have never used protool to log data. They do have a Facebook page which might provide some answers.

Yes & No.

I'm trying to figure out if 50% is healthy?

[studio54]

I think it is. V9 goes even high than 60% on mine.

stop worrying about it and youll be fine

do a wide open log and post it, part throttle is always going to do funny stuff

That's fine.

I wouldn't worry about it.

Mines at around 50% on WOT, and I daily it on a Stage 1 93 octane.

As you go up to 1+/2/2+ wgdc will increase.

V9 has slightly higher boost and timing, according to MHD, so depending on what stage you're running that is expected.

[nicky dj]

@MD - V9.1 e30 it idles around 46-48%

There are tons of datalogs on here that you can open and click on WGDC bank1 or 2 to see how it relates to boost targets and rpms within that log.

Generally the higher the boost target, and the higher the rpms, the more duty cycle your boost solenoids will request in order to maintain that boost target.

A lot of the logs I see on here running 17-19 psi of boost hit a WGDC of over 70% by the time they are at 6K rpm.

At idle a 50% duty cycle seems to be common.....but it depends if you have chosen to use the wastegate rattle fix option or not. This will apply more vacuum to pull the flapper further away from the turbo housing, so in my case I have a 60% duty cycle at idle.

But as others have already stated.....a better indicator of turbo health is how well your actual boost follows boost targets. As turbos grow old the wastegate mechanism gets loose and won't seal tightly anymore...thus you will find that actual boost starts to lag behind targets.
