J12 has to be cut for datalog to work probably?

also my alternator output is kinda high, battery will be from 14.6-15v while the car running, i dont know if that affects anything?

im using the oem spark plugs, and it does it even when the usb cable is not connected to the laptop.
i made a run with on board datalog on, then i hooked up my laptop and i check datalog and it only datalogged for 5 seconds, it froze between 3000 rpms and 6000 rpms after that it started working ...

so everytime my s300 starts datalogging it freezes all the time now, it used to never do that, i have my on board datalog to start at 3000 rpm, and when it starts it freezes around 3500 rpm- 4000 rpms and then it works again, its really annoying since i cant tune the engine very well since this ...
