EFI connections tried the 24x reluctor wheel on a dampner and they had too much noise on the hall effect for it to work properly. But I have used a 7x that I made and it was bolted on the outside of the dampner. I didnt have any noise issues, but that's a fairly low resolution compared to the 24x.
GM says they placed the reluctor on the LSx engines towards the back of the block because this is the "quiet" zone. If GM went through this kind of trouble, I imagine there was a good reason.

But at the same time, EFI connections 24x and 58x kits for the LT1/4 engines use the reluctor behind the timing cover. Their system seems to work, even if it's in the "noises" zone.

Thanks guys for all the info on the LT5 ignition. It's always good to see how it was done differently.
