V3 autocross map
Just reading about the new features on V3.1 and the ability to adjust and personalize alot of the tuning parameters.
I was curious to know what kind of setting would help in an autocross custom map.

Also, if you are trying to win I'd skip the chip, stay stock and get the widest R compound tires your class and bodywork allows |

If you do have to do the whole chip thing, I would say put as much power in the midrange is possible. Remember, you'll be in second gear the whole time so tune it to keep traction and top end power won't help you AT ALL. At autocrosses I'd say I probably spend most of my time in the 3-5k rev range. The only time you hit the top end is when you're speeding past the timing gate. I'm consistently in the top ten at BMWCCA autocrosses (no classes locally) with no chip, non-stock street tires, and sway bars. No chip required

Dave,
I'm not suggesting the OEM tires are the 'it' tires, I'm merely suggesting that I find my 328i with these RE050A II tires appears to have similar cornering ability to my old WRX with similarly sized Falken RT615 tires. Also, I just recently found out that the 335i comes with RE050A tires and the 328 comes with RE050A II tires. Supposely, (according to nasioc.com and I can't find the thread now) there is a non trivial difference in traction between those two compounds (the 'II' compound is grippier, and the 'pole position' compound is grippier still). I suspect this explains the differences in our experience with the OE tires |

How much cash do you stand to win when you win the autocross? I'd say, if the purse is less than $300, just run bypass plugs for the autox.
The real answer... Whatever gives you the most predictable power delivery. If power comes on in an unexpected fashion, you'll be doing damage control instead of driving. Predictable usually = flat like Fu Mingxia torque curve. ________ Pattaya property Last edited by satakal; 08-16-2011 at 05:59 PM.. |

So on a random note, it looks like I am going through 1/32" of tread every month (~1250mi of driving/month) .. I guess the OEM isn't kidding about the 140 tread wear rating Let me know how those Dunlop tires work out, since it looks like I'll be in the market for rubber soon too OP.. I doubt you are going to get rid of the chip, so just get max powA! |

if you're all stock besides the tune... bypass plugs so that you can see how you fare vs the other 6 cyl stock guys. The car has more than enough power to make managing it a challenge. IMO, take one variable out of the equation and focus on the rest. That one variable being "rediculous torque".
