Happy New Year!
I posted this question on the other site too - see post 29 in this old thread of Louie's. Note that I could only get into the other site from my phone by using a DuckDuckGo browser:
https://rennlist.com/forums/928-forum/3 ... ion-2.html
So, in a discussion about tuning my motor, and specifically about individual cylinder knock sensing and corresponding ignition retard, I was once told that the best approach was to retrofit 87+ computers to my 86.5, retrofit both knock sensors (done), add a Hall sensor, change my flywheel, and do some rewiring in the CE panel. I prefer to avoid most of that if possible and see what I can do with my stock computers running the 6.5L Stroker motor.
I am willing to go through the pain of tuning my 86.5 (stroked) motor's stock computers (LH2.2 + EZ-F) using my sharktuner, but I would also like the safety of knock sensing and corresponding retard. In the above thread, Louie Ott recommended the J&S Safeguard Vampire model:

for the 928 which seems to be able to provide per cylinder knock detection and corresponding per cylinder ignition retard.
Has anyone installed this on an 85-86.5? How does it provide the per cylinder feature? It looks to me like it just counts ignition events and knows how many occur per 2 engine revolutions? Will this work without having a Hall sensor to track cam rotation (which is what I think the Hall sensor does)?
Thank you, in advance!
