Thread: Knock learn stuck at 0.11

    Knock learn stuck at 0.11

    What makes my knock learn stuck at .11? P59 6.0 Truck Norris setup. FYI I know OL WOT Fueling is dead on target I just removed the wideband prior to this pull. I have also lowered the 2-3 shift and timing some in the tune vs what the log shows. This truck is dialed in really well tho. But I was just curious why Knock Learn is where it is for future knowledge.

    Its my understanding that the knock learn factor is the indicator of which spark table its referencing from. IIRC, when using the high octane only the learn factor will be a 0. As it sees knock it can choose to blend in or completely use the low octane table. So, as the knock learn factor increases to 1.0 it is referencing the low octane completely. Anything inbetween is a blend of the two tables...

    Gen III is backwards from Gen IV. Gen III with a knock learn of 1.0 is on the High Octane table.

    You have this setup for a ton of advance. i'll bet it's in low octane mode becasue it has been knocking. despite it not showing any knock in the log.

    But you have 28 degrees at WOT. too much

    Not saying its pretty. It drives well. and the airmass that this engine runs in at WOT it starts at 20-21 and peaks at 25 now, the intake tubing IMO has limited its potential. Part throttle drives good. No surging.
