Here you go. Its all color coded only one error and that is it's "Spark A" comes out of pin 36 on the DB37. You'll set up for GM7x, "no" cam signal, Rising edge, going low(normal) and waste spark under tachinput/ignition settings. Then you'll set your timing to fixed 10 degrees trigger angle/offset(deg) and use a timing light. For example my car wants -6.20.

If you want you OEM Tacometer on your dash to work and can split the VR feed from the crankshaft position sensor. You also might have noise issues with the trigger so you will have to adjust R52 and R56 pots to clean up the signal.

You're all done now on to tuning...
