Your VGT% at Hot Idle?

So, what does your VGT% show at hot idle? And what determines the VGT%?

I have been told my VGT% is too high at hot Idle. Mine still, even after new turbo, pegs at 85% at hot idle.

Also, which sensors are used to determine the VGT%?

My EBP at hot idle is 16.8.

Any other sensors I need to be checking that effects VGT%?

Sean mine does the same thing. Originally thought it was because the veins were sticking, but even after cleaning the turbo it still sits right there at the max. Haven't noticed any ill effects from it either. I had read before that you should never see 85, but I dunno. Reading is taken off Scan Gauge.

hot idle iirc should be 85%

well the Operating Value calls 73% at Hot Idel

VGTDC # 0 73 43 0 - 100 PERCENT Turbo Duty Cycle

IIRC mines right in that 68-73%

I will go for a ride here in a Minute and check and cast my Vote Sean

Does it Idel Bad or Just the Number seams Off???

I remember going threw this awhile Back seemed like folks was hiting in 60s-80s IIRC

MAF & BARO & MAP

Im shure your checkkiing at KOEO

But also need to watch as you drive to for erratic readings and stuff like that

At Hot Idel ECT 190*+ VGT% was 60% and 15% when Veins Sweep

Hot Idel In Gear but stopped VGT% was 60%

I didnt see 60% VGT so I couldnt vote Sean it was out of my range to

Also 60% VGT was Steady at Idel AS long as the veins didnt sweep

Okay, I'll bite.

On mine, at about 195*F at idle in PARK, EBP_A reads between 16.8 and 17.0 psi. MGP reads between 0.36 to 0.39 psi. My VGT duty cycle remains steady at 68 %. Since the range of duty cycles you posted, is out of my range, I couldn't vote.

Does this information help?

Mike can you tell me/us about MGP or Manifold Gauge Pressure

Is it the same as Boost psi or MAP Minus Baro pressure reading???

What is it I tried to research it alittle the other day and didnt find a answer

The real reason I wanted to know what MGP is was because I was going to try and see if James D (He is the Guy at ScanGauge Company that writes the Codes we Need/want to monitor the PID) Could give us a Code to monitor it with our ScanGaugeII Units

Thanks again Mike

Yes sir!!! You are correct!!! MGP is the actual boost pressure.

Mine runs around 55% or so.

If everyone else is reading 75-85%, that could be a HYOOGE explanation of why mine won't get out of it's own way trying to come out of a stoplight.

The only time mine is at anything over 75% is at cold startup, and only stays there for a couple of minutes.

It's normal operating range is anywhere from 45% to 65% normally.

-------------

Since it's counter-intuitive, here's a little explanation here of how the VGT% works; it's a number that represents the duty cycle of the VGT solenoid. 85% duty cycle equates to the solenoid being fully extended, which closes down the vanes to their tightest configuration. Conversely, 15% duty cycle on the solenoid opens the vanes fully, allowing maximum gas flow towards the turbine wheel.

Keeping the vanes closed (or nearly so) at idle and low engine speeds mimics a tiny turbo that spools quickly and provides little lag. Opening the vanes as engine speed and load rises allows the turbo to act as a larger unit, which is able to produce larger boost flow as the engine requirements increase, without overspeeding a smaller unit, which would result in both overboost and turbine explosive failure over time.

(Also, in the emissions world, closing the vanes down under certain operating conditions provides the back pressure necessary to force exhaust gas through the EGR cooler and into the positive-pressure intake manifold.)

Benny, KOEO readings. MFv is MAF volts.

I think this is getting interesting. Where would the best VGT% be then? Ford says normal is 73% low hot idle.

As Frankenbiker shared, the way the vanes work, the higher the VGT%, the better off the line? And lower would make the truck work more to get moving. So, what would be the answer to getting the VGT% to the best spot. Ford's 73%?

__________________________________________________ ________________________

Here are some videos I took on the drive home tonight. The first 2 are doing 60 mph pretty level ground, cruise set. MFV is MAF volts. See anything odd in these? Let me know.

Xgauge reading - YouTube

Gauges - YouTube

The 3rd one is coming to a stop, then taking off. I didn't get a good full screen shot, but the 2 gauges on the right are: top right EBP, bottom right MFv.

Xgauge again - YouTube
