In the past i did something similar to read tach signal with PIC. The target project was an TachProbe for remote starter installer (like i was). It was reading Tach source and convert it into Cylinder reading. It's still on use and on *market* now. For this i just read the input frequency by using two Pulsin command to get the period of the input signal. With a simple formula i convert period in a cylinder reading.

maybe this can be use for your project too.

First off, I'd like to thank everyone for giving me some input to this starter project.

Mister_e, I went and purchased several LM2917 Freq to Voltage converters. I also picked up the 3914's LED drivers. I saw the tech application note 162 that showed how to make an automotive tach. That was nice but I want to go the route of using a 16877 PIC, since that is what came with my ME Lab kit (X1). Do you have any code that demonstrates what you did above?

Thanks for in advance everyone!
Cheers!
