This really sucks we are getting awesome snow right now and I can't go have fun in my awd car because of this lame ass nanny system. Anyone know if there's an after market flash or controller I can buy to disable this crap?

I find this odd because i had zero issues getting my 5spd to slide.
Mind you it wasnt entirely intentional but i would give it a little throttle, rear end started sliding out, let off throttle and the car straightened back out. So you guys are saying if it bury the gas pedal in the snow im not going to be able to slide through turns? Just trying to get a grasp on the issue. |

Now with my 2012 Impreza, I don't even both messing with it after the first 5 minutes. This is unfortunate, because I had a great time with two older non-ESC Subarus. One of those cars was a 1993 Legacy wagon 5 speed. I had 4 studded snow tires and driving that thing sideways in the winter made me so giddy I could barely stay in the seat. |

Yeah I don't think that button is very useful, seems to allow more wheel slip and that's it. My dealer said the only time you'd use it is if you were stuck in a ditch or something. I also wish for the CVT you could manually set the front/rear power split at 50/50 for snow driving. |

i thought i read the cvt had a 50/50 split most of the time. only went to 60/40 in some instances.

I thought it was a 60/40 split normally.

I dont think anyone knows that the CVT power split is, probably something closer to 90/10. The manual is the one with the 50/50 split

My dealer said it was 80/20 under normal driving conditions, but could not verify that from any other source I could find online.
And my understanding from what I could find is that it can send up to 50% to the back when needed, but no more. Sometimes I think I can feel/hear it kick in when I am powering into a turn from a stop. |

in order to get the MPG im guessing they messed with it a little.
i havent even tried the vehicle without traction control yet but i am a little interested. If i find a vacant parking lot ill do a little test for you guys in my 5mt Last edited by auskip07; 05-09-2012 at 12:12 PM. |

Oh geez, I'm tempted to just call SOA and ask them.

everything I've read says 90/10 cvt and 50/50 for the MT because it has a viscous locking center differential. Meaning if one end or the other's rotational speed starts to vary from the other end it hydraulicly locks. So it's always 50/50 with a minor amount of slippage just to power the locking mechanism.
The CVT cars have an electronically controlled clutch that the computer controls. So it's mostly front wheel until they start to slip, then the compter engages the clutch to the rear wheels. Next time I'm out and about in my 5 speed 2.0i I'll unplug the ABS unit and see what happens. |

IMHO (as a mech engineer) for the CVT equiped cars it wouldn't be all that difficult for someone to engineer/design some sort of controller box that would allow the user to adjust that center lock up. Either it's on/off or 0-5v signal or something like that. Would just have to do some work to figure out what kinds of signals that the electronic clutch can receive. But that won't change the VDC issue... That is purely software related, but again once the code gets cracked and is tuneable it can probably just be set within the computer. It all just depends on the demand and if its worth "mass producing" electronic gadgets that fix this. (OR a dedicated and skilled group of DYI folks who engineer and open source fix). |

I submitted a question on Subaru's website asking for the range of possible torque split for the CVT. They responded pretty quickly, but here's what they said:
We do not state a normal torque split for the AWD System equipped on our 2012 Impreza models with CVT. That is because the torque distribution in continually changing due to changing conditions. |

Yeah but when you just take off at 20% throttle in fair weather conditions, nothing is slipping or will be slipping. The car isn't trying to continuously adjust torque split to keep that 20% throttle under control. It has to have a default it runs at until something happens (full throttle application, wheel slip, turn rate/yaw sensor mismatch...) Making constant adjustments for no reason would just cause premature wear.

of course, i have no clue if that is really the case, and also since this is my first AWD, i really am just speculating because i like to as a scientist (which i am for my profession...just not an ME or auto industry scientist! ) |
