Open Discussion - Front solid axle conversion

Dave are you sure QDII disables traction control differently that QTII?

If you're in 4 low with QDII and have your front diff open, Itll probably set a DTC for front diff clutch performance. ... but thats not really a big deal.

Which gives me another thought for the QTII guys. Adam do you have a place with loose dirt or gravel that you can drive circles on with your front locker engaged? ? Wondering how your traction control system will react when it doesnt see different wheel speeds while turning (ref steering rack issue)

I can probably find somewhere to test that out

Just tested it out. 4high with front end locked making figure 8's on gravel parking lot. The traction control was fine and never kicked in. I can definitely tell when the front end is locked. You can feel it in the steering wheel

Thats awesome. I was trying to think of how the programming logic would work and came up with a few scenarios where equal wheel speeds wouldn't activate traction control... basically a case of "divide by zero" where I would presume the programmers would default to no traction control necessary since its an impossible scenario based on design (until you throw a locker in)

... sounds like another +1 for QTI and QTII guys who want lockers! !
