Dyno Setup Q's - Tie downs, Tach Pickup, DCT Gear Selection
I'm renting some time at a dyno shop this weekend for a few hours to tune another car (not M3) for a friend and I figured while I'm there I should get my E92 M3 on as well. I was wondering where is the best place to tie down the M3 on the front and rear. Also where is the normal place to pickup the tach signal? My car has the DCT and I've read conflicting answers but I figured I'd ask again, which gear is best to run in? 4th or 5th?
