Borg warner turbine speed sensor?

Hello, just wondering if this will work with S300 to datalog, The speed sensor is powered by a +5V supply and the return signal is a variable frequency square wave that has maximum amplitude of 5V and has a 50% duty cycle.

No, the turbo speed output is a variable frequency square wave and the S300 analog input is analog, so it won't work. Normally the turbo speed gauge has an analog output you can use.
