Hello, trying to figure out how to get a tachometer signal straight from the ECM on a 2.4L LE5 Ecotec engine. Please let me know what I can do in order to get a tach signal without having to purchase a $100 tach driver! Thanks in advance!

Study the pinout for the main wiring harness. Tap into the wire for the crank signal going into the PCM for your trigger wire.
