05 f150 ignition timing issues

[mxguy1286]

Hello all,

I am having a issue with a 05 5.4 engine f150. The ignition timing that is logged is no where near commanded timing and I can not figure out why. Even after all the subractors for iat, coolant, and lambda it does not add up at all. I should have at least 15 degrees of timing more but I dont. Any help would be greatly appreciated. I have attached two logs, one I did not have knock sensor logged. The knock sensor readings are odd from what I am use to seeing as well.

How are you telling its knock retard? Im curious as all the log shows is a knock sensor value that mean nothing to me without knowing a threshold on what value is high or low. Its not like a gm where is says knock retard or anything. Thanks for any info!

I guess by looking at second o2 sensor that is 50mv when wot.
