You would prob spin more when both wheels turn and u have enough power to loose traction.
Can't fix going on power too early.

I guess thats assuming you are powering out of a corner as opposed to breaking too laaaaaaaate.

Nope, it was because without an LSD the car was a bit too unpredictable. It sort of squirms and wiggles at the back rather than being a nice progressive slide. Suddenly both wheels would have equal traction, both spin and bam facing the other way.

It's the last corner which is a hairpin, so I was powering out a bit too early Getting some nice slides the previous laps so I decided to give it a real go. Whoops

I've spun my 1er once now as well... these wheel bases are just too damn short... whereas the E92 was brilliant in the corners, very progressive when sliding out.

I'm pretty sure it's because your 1er also has about 3x the power of your E92. The 325i has barely enough to even get a decent slip angle.

325i still has plenty of power to get sideways especially in the wet... maybe the power was just easier to modulate.

Btw in peak hour driving I turn off my procede... I find with the procede the torque comes on too strong and it makes for a rather unpleasant drive... much smoother in stock mode lol

i think it just takes time for your to adjust your feet to module the power delivery better (with the procede)?

I used to be like that too.

I was always under the impression PROcede had a smoother power delivery compare to the JB, or so from what I read

But yes both tunes are good! No tuner wars please..

I always thought you little 1er's were pussies with fat cars

Seriously though I did go back and forth when deciding on a tune and in the end it was a coin flip! IMHO the V5 and JB4 are the two standouts to pick form the rest of you F**kers can go to hell

No seriously, seriously IMHO go the N54 FTW, those 55 chaps...... Aw shit i better stop

Were all winners

Complete and total crap.

The reason they use an open diff is the car does not tend to oversteer, it will understeer before the back end looses traction so the punter will lay off the gas or hit the brakes and the car will start going where they intend it to go.

The problem with oversteer vs understeer is over correction, get your butt onto a skin pan and see if you can do figure of 8's. If you can then oversteer is your friend and an LSD in order. Why do you think BMW Sydney has so many 'demo' m3's for sale all the time, over enthusiastic sales reps and customers coming un-cropped at roundabouts.

Most mug punters with an LSD get the back out a little, dial in far too much opposite lock, the next flick is bigger and so on and so forth until they hit a tree or telegraph pole.

LSD while helpful under the edge of traction is not your friend unless you learn what it does and practice the technique.

I can have traction issues all day if I wanted to even with LSD, AD08's, coilovers and M3 suspension bits. But my right foot has been trained such that they are only issues when I want them to be.

A kia can have traction issues if you don't modulate.

Thankyou for saying what I was thinking.. after all, if an LSD was the proven "safer" option over an open diff .. why would BMW take it out of all bar their M Cars? (ignoring cost for a moment of course!)
