tuning avant rs ?

[thespaz]

I have been trying to tune my audi avant for awhile now, I have it down pretty good but it still spins tire when I drag people. What should my tunes be set as for dragging?

Dude, if you mean an RS6 firstly it has 800bhp when fully tuned so its very hard to not spin any wheels, even though it is a 4WD, but i suggest you do a 30/70 F/R split and just tap the throttle until it hooks up and ****s **** up

A 50/50 torque split will work better to reduce wheelspin.
Also lower LSD initial and accel help reduce wheelspin, of course that has to be balanced against the impact those lower values have on acceleration when drag racing.

i find that you get front wheelspin when you have 50/50 torque split

If your getting just front wheel spin then you need to adjust the LSDs. Lower the front initial and acceleration, raise the rear initial and acceleration. Keep adjusting both by very small amounts, 1-2 points, until either neither front or rear spin or else both spin at same time. If neither front or rear spin try raising both LSDs until both spin then reduce to just below that value. If both the front and rear spin try reducing both LSDs until you find a point that you don't get wheel spin (may not be possible so find a point with minimal wheelspin that still gives solid acceleration once tires catch traction and in higher gears.)

He's talking about drag racing so that doesn't apply. Usually LSD is set 10/60/60 front and rear.
Also 50/50 torque split is not ideal. You want a little wheel spin so the the car doesn't bog with the long first gear needed for drag racing. 40/60 would be a good place to start.

Please explain why in drag racing a 50/50 torque split would not be good. You should be able to transmit more power to the road with less wheelspin thus getting a better launch. The only advantage a 4wd has in a drag race is getting the faster launch so anything that allows you to transfer the most power with the least wheelspin should be better. When you start reducing front torque in favor of rear your losing some of your advantage. Using the LSD to help limit the front wheelspin should see more rewards as once the front gains enough traction it will lock up allowing for that extra power to be transfered extending your strong initial launch, and in higher gears it won't factor in as you should have little to no wheelspin by then.

My point was you want some degree of wheelspin. Some tuners believe that the LSD has an effect on drag racing but the vast majority say locking it up is the best bet to lay the power down equally to the wheels. And remember the LSD only has an effect when the wheels are moving at different speeds,hence why it is so valuable in grip tuning and not really important in drag racing.

Well, I went and tried your set up and I got front wheelspin and I don't like front wheelspin on AWD cars, you have more grip when the rear is pressed down and it's also easier to get the optimal launch with 10% wheelspin, use 40/60 front rear I think .
