It looks nice. I'm unsure though, what good is logging if you can not change a problem you do find? I'm with
wookwook, HPT interface is 299$, and will do worlds more in comparison. Then you have the option to change things if you buy the credits for the car. I have the P3 vent mounted gauge myself, it does not Log,
Trochoidal is correct, but it is nice for instantaneous data, such as AFR ect...
