Hi,

Here's how I enable it:

Data Acquisition Version="0" // Version of vehicle data to write out
Data Acquisition Rate="10" // rates 1, 2 ,5, *10*, 20, 50, 100
Data Acquisition In Race="1"
Data Acquisition EXE="C:\Program Files (x86)\MoTeC\i2\1.0\MoTeC.exe"
Data Acquisition File="data.spt"
MoTeC LogFolder="MoTeC\Logged Data"
MoTeC Minimum Time="20" // minimum MoTeC recording time (sec)
MoTeC Multiple Logs="1" // generate unique filename for each new log

Note that you will need older Motec version, I use: mi2_pro_1.0.21.0030

IIRC You also need to complete a lap, and logs will be in game root under "Motec/Logged data" Good luck
