And shutdown logging?

[Gjkrisa]

Hi does any one know what I can log to see what causes the AWD to shut off during sliding in the snow.
This is all I have for the first and only time it shutdown today. After this I just kept the rpms a little lower I was targeting third gear mostly in this but after targeted 2nd gear and didn't have the AWD shut down.

Here is what I had for the AWD not shutting down maybe with temps higher also helped.

I am interested as well.
My Flex goes all front wheel drive after a long drive.

Is your temp reading in F or C?

Some info on ptu heat and awd shutting down for you:

All my temps are f as far as I know

Perhaps "Torque Source"?

I found this on the SVT Performance forum. Perhaps AJP Turbo can comment on the accuracy of these for other Fords. 4 matches up with a rev limiter issue I was having, so maybe it's the same for all Fords??

TQ_SOURCE Identifies the source of the torque reduction requestor

0 No Torque Reduction Requested (Torque Control Off)
1 Torque truncation, transmission
2 Traction Control
3 Vehicle Speed Limiter
4 Engine Speed Limiter
5 Tip-in shock Control
6 Tip-out Decel Control
7 Torque Shift Modulation, transmission
8 Engine Oil Temperature Control
9 Fail Safe Cooling Control
11 Turbo Charger
12 Passive Anti Theft system (PATS)
13 Tip in Torque Control

TQ_SOURCE Source of torque reduction:

0 Driver Demand
1 Transmission torque truncation
2 Traction Control
3 Vehicle Speed Limiting
4 Engine Speed Limiting
5 Tipin rate limiting
6 Tipout torque
7 Transmission Shift Modulation
8 Engine Oil Over temperature
9 Target N
10 Not Used
11 ETC FMEM - RPM Guard
12 PATS
13 OSCMOD

You can also find that list in the tools tab in livelink.

I dont have a sct programmer yet is there a way to view torque source in torque?

I'm not a Torque user, so hopefully someone else can advise.

Sweet, thanks! I had no idea! I'll have to see what other goodies are listed in there.

For anyone that does use Torque...

Back when I was experimenting with PIDs I was able to find one related to Torque "Source" reduction.  The PID I believe was 2203AF on my 2011 but I never really did anything with it so I don't honestly know if it is valid or not.  I would speculate the formula would be the standard...

Equation: (256*A)+B

You would need to create a custom PID and see if you get the values as listed above and if they roughly corresponded.  Alternatively you could break out FORSCAN and use that to see if they have it readily available and already decoded.

Interesting I've got this from forscan

Well whaddya know!  Interesting list.

 

[Gjkrisa]

So now how do I find out what pid they used ... I'm able to graph it and save  graph I didn't do anything except drive home and make the card slid some tried to rack the speed to 100 but as soon as car made it to 30mph car said no. Damn smart cars .

My phone let me put the logs in

 

[Gjkrisa]

Geee the car is lame I go to log it shutting down and no madder how hard I push it never does but not logging and it happens so quickly...

I put some heat into the ptu

Just curious, but is it happening at a shift point and/or high RPM?

Brad hopped me up so much over stock on a 91 tune that I ended up hitting the rev limiter with my stock shift points and had big drop in power and what sounded like free spinning engine. I thought I blew my trans, but he just needed to pull up the stock shift points a touch to prevent hitting the rev limits.

I could see if you were spinning in snow that you might rev up a lot faster than just charging along on dry pavement, so maybe it's hitting some sort of rev limit? My "Torque Source" read 4 at the time of my events, which indicates "Engine Speed Limiter".

 

[derfdog15]

If you are hitting the rev limiter, or bouncing off it is to speak, as MiWiAu said, you should hear a babababa noise. I got my car to bounce of the rev limiter the other day when roads where wet, and traction control was one (was an accident) so I have no doubt it could be happening in the snow.

 

[Gjkrisa]

I'm keeping the revs with in 2nd gear I don't have a tune to allow bouncing off the rev limit if I hit limit to much it will shift I'm waiting to get home to share what I got from tourque and find a way to read the log I saved from forscan I thought i could load it on my phone

But I think there is just enough resistance in the snow that keeps the torque happy to not shutoff awd. Have to wait for my spot to get icy to test that theory out.
