Signal spike

I posted this on Psychobike....figured I'd try here too. Here is my issue..

I'm trying to log using a WEGO...but no matter where I try to pull an RPM signal I get these weird spikes. I thought it was just the wego maybe..but today I watched the live view on my PC3 and saw the same thing. The wego is pulling from the coil...and the PC3 from the injector signal right?

I've tried moving power and ground....re routed wires away from harnesses and other wires. I don't know what else to do at this point since the problem shows up on both devices. Any ideas..
