Car 10 is a user defined vehicle constant (data/vehicel options/last page) it is used here only for the orientation of the DL1/DL2 in the car, relative to the steering wheel pot. So since I have no easy way to measure if the DL1's orientation is a few degrees from perpendicular to the longitudinal ...

RT (IF(VAR_07<50,0,SIGN(VAR_04)*( (CAR_5*VAR_04/SQR(VAR_07)) -CAR_10*((VAR_32/90)*1.571)))/1.571)*90 With Var07=Speed, Var04=Lat G and Var_32=Steering in degrees and the Oversteer units is deg. Setup Car5 as wheelbase in Meters and smooth over .2 sec. RT does not have the Stat_mean function so Car1...

Simple download Motec and open the maths module Motec smooth(choose('Corr Speed'[km/h] < 50, 0,sgn('G Force Lat'[m/s/s])*( ( 'Vehicle Wheelbase'[m] * 'G Force Lat'[m/s/s]/ sqr('Corr Speed'[m/s])) - sgn(stat_mean('Steered Angle'[rad] * 'G Force Lat'[m/s/s]))*'Steered Angle'[rad])), 0.2) RT (IF(VAR_07...

Well it can read them for me, but on occasion there seem to be things it does not like and no error message appears. Have a close look at variable names and units at the top of the file. In the first pass that is what LapSim is parsing so you can assign channel-names to input variables. As mentione...

Where can I find the preset calibration?

Change in Heading is an interesting channel to export since it effectively is the Yaw rate. Make sure you have it as deg/s Lapsim does not seem to like rad/s.

No trick, just works... assuming you have version 2006.3 and make sure you have "time" as the first column and don't export more then 1 lap. After selecting the file be patient takes a while to load the data, then have a car setup prepared to load with the data. Great tool to analyse your ...

Not sure what you are trying to calculate, I use rpm/wheel speed. This gives a trace that steps through a different level for all gears. Yes there can be a bit of noise that you could filter/smooth but from looking at the trace you can see what gear you are in. The exact gear ratios you don't really...

Or a software feature to correct the offset....

Been thinking about that, although it may be a matter of definition. From a steady state point of view it is both slip angles, from a dynamic pooint of view, we are measuring the input into the system, it is initially the slip we introduce to the front tyres and over time some of it will transfer to...

Molstly works, did some track mapping 6 month ago and the position accuracy is still acceptable, porbably about 1-2 metre off . So would be nice to set an offset manually on a "map" layer.....

Good old Alt+PrtScrn (that seldom used key at the top right corner...) captures the current window, so maximize your graph or track. Then use paste in Windows Paint and save to JPG (if you have a recent version of windows..)

Well this is almost what I just did. We have a sterring wheel input and the DL1 calculates the instant radius, (I assume from Speed and G-Force). Assuming the required steering angle is the Radius divided by the Wheelbase of the car, (sounds too simple but confirmed by Milken&Milken) the slip an...
