I know some LS engines have crank sensor issues as well. Might pay to go external wheel/sensor or key the damper and buy a cheap MSD flying magnet setup.
its the right sensor. i never lose signal but the frequency distorts on the system log. which tells me interference is pulling on the signal as rpm increases. as its a 4800-5000rpm(most common rpms) and above error.
im about to cap off half the plugs and try that. if its rmi this should cure it with the quickness. as 4 plug wires vs 8 per side. this should make a massive difference in that. as it cuts half of the electrical energy radiating per side. also hunting for local stock valve covers to mount in stock locstion as well.
