I've been through the manuals and double checked all the build steps but I'm stuck at getting the engine speed to show in tunerstudio. Tunerstudio logs cam and crank signal during composite logging, but the tooth logger graph doesnt look like it should. Vehicle is a 1956 Ford F100 , engine is from a 2007 Chevy 6.0L LQ9 with the 24x reluctor (LS1). Being a complete newb, I had the most trouble with the ignition options during the megasquirt assembly. I did not install high-current ignition driver circuit, but instead installed the VR sensor circuit components utilizing MS3X outputs for logic spark, idle valve control. 160lb low-z injector drivers with a peak and hold box.
Im so close, but just dont know what else to try. any help would be greatly appreciated.

I think you have the crank signal connected to the cam input, and vice-versa.

That fixed the problem. Thanks for the help, I dont think I would have ever figured that out. It started on the 2nd crank after I swapped the wires.

Was the problem the red with white stripe jumper wire in the last pic ? I have the same exact setup but I don't have that jumpered, I am also having trouble trying to get a rpm signal.
