M settings on bumpy roads

swiss_cornholio · 07-14-2008, 06:58 AM

I have set my M button to EDC=Sport and TC=MDM. On smooth roads these settings work perfectly but on bumpy roads the car kind of jumps around and the TC cuts off power.
Now which setting should I change? EDC=Normal/Comfort or TC=off or both?

On public roads, which are falling apart in Boston, I use MDM and EDC Normal. If the road is really bad, then I'll switch to EDC Comfort until I clear it. That seems to work well for me.

Just temporarily set your EDC to Comfort until you clear those bumps.

Is the softer EDC setting helping the traction? Or does TC=off (and a little wheel spin) give maximum acceleration?

Not sure why you want maximum acceleration on a bumpy public street? I just try to ride out the bumps to get to even surface. In a 0-60 contest on a flat road, comfort is supposed to give you optimal traction I think.

Some mountain roads are quite bumpy and I like to have optimal acceleration out of corners...

So far I have been careful with the traction control cause I don't wanna do a 180 spin on a public road...

Something tells me accelerating through a turn on a bumpy road might not be a great idea safety wise.

Yeah, I wouldn't turn TC completely off in those circumstances. EDC = Normal should be fine. If it's bumpier thant that allows, you need to go Comfort.

OMG - I just hit some bumpy road at well over 100 mph- even the cofort setting didnt help. does EDC go to full stiff over 100 mph or something?
