Has anyone ever added a knock sensor successfully to their bike?
I just picked up a very nice supercharged VMAX, ground up restoration and refit of EVERYTHING....complete bike rebuild has 50 miles on it. Should be running around 14 pounds of boost in the 170-180HP range. I'd hate to blow it up due to running lean and/or detonation/pre-ignition/knocking/pinging.
I just got a dynojet wideband commander setup for real time monitoring/logging air fuel ratios. That takes care of the running lean scare.
Now I need to safeguard against detonation/preignition.
What I see thus far, my options are....
1)
Knocklite...varying reviews...decent price $200

2)
Phormula Knock analyzer...bit pricier $400, has some videos to see how it works...no reviews that I've found... video uses a soundtrack to demonstrate the effectiveness of the analyzer, but knock is so painfully obvious in that soundtrack, its ridiculous.....DOnt need an analyzer for knock that obvious!!

3)
J&S Safeguard knock controllers $500
Integrated knock detection with adjustable individual cylinder retard and allows retard for boosted engines at varying rpms and boost levels... Lots of adjustability and can actually aid in tuning the engine better as opposed to one way signal like the others... Closed loop knock detection and ignition control.
