M5V8 337 Report post Posted March 15, 2012 Not exactly a BMW but I thought due to time constraints I might need some other ideas. this is for my R32 GTR racecar. I have an event on sunday so this needs to be sorted tomorrow. The car is fitted with a 2WD switch in the cabin very similar to this: http://www.skylinesaustralia.com/forums/to...itch-to-an-r32/ Randomly the car has started turning itself into 2wd. It does this when the car is at low rpm. And seems worse the more i drive it. Of course I can just flick the switch & stop and it will go back to 4wd. My thoughts are: dry wield broken wield dirty or damaged switch Anyone have any thing else I should consider? Has anyone heard of this happening to a GTR ? did they have a switch installed?

gadgetman 0 Report post Posted March 15, 2012 Seen as you are open circuiting a supply line to the 4WD & ABS controller your thoughts are correct. The other possiblity is the controller itself. You would have to remove the switch mod to confirm this though. Quote Share this post Link to post Share on other sites

Other than thinking I'd remove that switch to be well sure of no 2wd moments up Mt.Vic on Sunday. Quote Share this post Link to post Share on other sites

It's happened before. And it's not a road to toy with.Yeah I'm thinking now to take out the switch see if the problem occurs then re-wield it back in. It's too much fun to leave out.

hybrid 1042 Report post Posted March 15, 2012 Chat to Ollie (Hi-Tek), they changed over to a digital hicas sensor away from the stock analogue one. Also I was under the impression GTR's are 2wd all the way up till you break traction? ps I aint no GTR expert Quote Share this post Link to post Share on other sites
M5V8 337 Report post Posted March 15, 2012 (edited) Fixed the commets aboveah hahahaha..... yes very trueAlso I was under the impression GTR's are 2wd all the way up till you break traction? - yes correct. Any slip angle or wheelspin engages the 4wd to drag you out of trouble. So they need to be driven like a Rwd from the back. Which is giggle inducing fun Edited March 15, 2012 by M5V8 Quote Share this post Link to post Share on other sites
Hi-Tek 3 Report post Posted March 16, 2012 Sorry Darren, No idea mate. I'd post on Skylines Austraila though, there are some smart chaps on those forums. See you on Sunday. Quote Share this post Link to post Share on other sites

M5V8 337 Report post Posted March 17, 2012 (edited) Found it. Loose block connector. Don't know why I used it. Two snap connectors later. Problem solved! Cheers to those whom chipped in. Roll on Sunday Edited March 17, 2012 by M5V8 Quote Share this post Link to post Share on other sites
