So my problem is that everything works good until a minute and then x-sim pops up with "Error writing on serial port"
I think it happens because sometimes my cpu usage is at 100.5%
But I really don't know, please help, me people! Thanks in advance!

I'm going to change the shift light so, I can determine the rpm at which the led turns on, but as long as I don't get this problem fixed I'm not really gonna be doing much else.
Thanks in advance!
