Trying to datalog the knock sensor and need advice if its normal. Im getting a voltage reading anywhere from 9,887.000V to 65,535.000V these numbers dont seem to make sense. Theres no SAE pid for knock sensor, just Ford Pid for knock. it seems to be maxing out at 65,535.000V under WOT but still seems to be following MBT and not pulling timing nor any audible knock

sounds like your logging the ad counts input with no equation
might want to shoot in a ticket to get it looked at
Thanks decipha, so I would assume if true that 65,535.000 would be 655 ad count?
no
65535 / 64 == 1023 ad cnts
Well wouldn't that mean its registering knock if it equals 1023 ad count or 5v. If that's the case there's no auditable knock. Even with stock tune I logged those numbers
whos to say its logging knock? again send a ticket in to get it looked at.
I'll get one in, I havent heard any knock so I'll just leave it as is till they get it ironed out, thanks for the help
