Wheelspin Datalogs needed

OpenFlash · 02-24-2010, 05:41 PM

EDIT: We have enough data. Thanks for all the response guys.

Hi guys,
I've been working on a little pet project that is almost done. Before I finish the final calibration, I just need some datalogs from v4 users NOT running aftermarket LSDs (which is probably most of you).

What I need is logs of wheelspin in 1st and 2nd gear. Basically, turn your traction control fully OFF (press and hold DTC button for 5 seconds) and take off gently from a rolling start. Once you're moving along at 10mph, stomp on the gas and let the wheels light up until you hit redline. Of course, only do this on a closed course and NOT on a public road.

Please note that I'm looking for logs that show a progressive loss of traction. Not a burnout.

Please capture:
Roadspeed (important!)
CAN dbw throttle
Throttle
CAN actual ignition advance
Boost set point
Boost Control DC%

Please keep the logs short (under 10 seconds) and email them to me at shiv@vishnutuning.com. Please put "V-diff data" in the subject line

omg sounds like fun... do you mind if its on slightly wet roads or are you looking for traction loss on dry roads?

Either wet or dry surface is fine. All I need to see is the transition from traction to no traction.

Just double checking; wheel speed is road speed when data logging right?
