This is a solution online for a tach hookup for an LS swap, it is still a 12v signal. Should this be sufficient?
12V source -> 10K 1/2w resistor -> Analog input.
Can the Analog input be configured to read 12v?
Thanks

Re: LS1 RPM Signal from Crank Trigger
Thanks for this information. I have tried wiring in the crank signal, but it is 12v instead of 5V so unlikely to be suitable. What resistor will I need to use after the tach signal as a pull up?

Re: LS1 RPM Signal from Crank Trigger
I am using the standard 2002 ECU, I think it is called a P01 and its a few years before CAN.

LS1 RPM Signal from Crank Trigger
I am using the analog inputs on my LS1 to set up my turbo lamik, and I'm trying to find out settings for the crank trigger. Has anyone done this before using the factory ECU? I have already set up brake pedal, TPS and MAP sensor settings so once I set up the RPM I am ready for first startup ...
