1 pointLooking at your fault codes looks like your chai has jumped, consequently putting your cam timing out of range of your cam sensor. Could also be a stretched chain or a malfunctioning chain tensioner. Try looking at the condition of your tensioners for signs of low tensioning pressure, as it could be enough to put your VVT out of range.
1 pointVery cool! I'll try it out. Thanks for doing this!
1 pointI found it hard to believe as well, until i dug a little deeper. Turns out, theres this option for something LIKE a LSD... on cars with the stability management option, apparently the computer already has alot of control over the brakes. so what it can do is take constant measurements of both rear wheels, and apply a tweak of brake to the spinning one. on a conventional open differential, this makes more torque goto the other wheel. it does this so fast and so well, if you dump the clutch (with PSM off) it will leave two black marks... if you have one wheel off in the sand and the other on the road, you wont get stuck, etc... but heres the nicer part.. at higher speeds, (45mph according to Lorens post above) it doesnt do it.. so you can get the excelent high speed cornering of an open diff, while still being able to snap the back around with the throttle when autocrossing... just like a LSD. add to that, the open diff weighs less..(and its rotating mass) and the system adds no weight, as the hardware already must exist for the ABS... it becomes a software-only upgrade at that point. its a very cool little feature.
