Does livelink/SCT let you watch custom PIDs?  I'm trying to remember from my X3 I had previously but I don't believe you could.  If not you will need to pick up Forscan or use Torque (or something similar) to monitor it.

Not sure, I am new to sho tuning. Used a moates quarter horse and binary editor for my 93 mustang

Ok, no need to log this. The ecu must put the car in fwd when there is low tire pressure. I just got my new wheel today, got the tire swapped over. No more ridiculous spinning of the front wheels. Instantly went away. Can't believe nobody else ever had this issue.

Always a first time!  Good to know, and glad the "issue" is an issue no longer :thumb:

Diameter difference must've put it I safe mode. Actually makes sense.

Did the awd off notification pop up?

 

[f8tlSHO]

It was doing this before the donut was on, no it didn't pop up

Are u kidding me?...there was a donut on?....wow u should've put that in your first post...funny how good details sometimes come out later

The wonderful features of the remote start would of avoided this predicament. Z

 

[f8tlSHO]

Wasn't a donut right away, I filled the tire up daily until I got tired of doing that. I use remote start all the time, what does that have to do with it

The remote start feature is disabled if any of the tpms detects a low pressire tire and stores a code on the dashboard,great to hear you resolved your issue. Z

 

[f8tlSHO]

Dunno, I didn't have any codes and I start it remotely all the time.

It has not happened with stock tune yet. So the dealer will not be able to help. I think it's more sensor related than ptu because as soon as I changed the tune it went away

Were there any codes set? I know with mine I got a communication error code when it happened once where everything shut down including the AWD.

Dude you have an awd car that's supposedly blowing off the tires with a flashing dash light...it sounds like the dealer could help...sometimes there is way too much speculation on problems here....sometimes when I race I get a service advancetrac message..I think from brake boosting and launching hard...then I restart the car and it's gone

All very true, that said he cannot replicate with the stock tune. At least if there are any codes set it might point him in the right direction. It's a little hard to walk up to the manager at the dealer and say "dude I have a problem with my car, it roasts the tires off it when I have my tune file loaded. Can you help me?"

I get that occasionally also, only when I drag race, not on road courses.. on restart it goes away.

Rule #1. AWD cars must have all same diameter tires.

Must be a pretty low psi to cause the awd not to work. People have been airing down tires at the track without issue.
