I wouldn't be concerned with blips to 3.5.
At 3.5 you are well with the ECM's ability to deal with impending knock.
If you were seeing 4-7 consistently then I would reload the 91 tune.
The ECM is always looking to advance up to the knock threshold then it will retard and start the process over. Especially not surprising because you've loaded a fresh tune.
You will never be KR free and if you are then your tune is probably leaving power on the table, at least in spots.
And then there's false knock.....I was getting a bunch of KR on wot downshifts only so I had Torrie soften them a tad and it went away. Your knock sensor is a microphone so changing things like shift pressures can induce noise into the freq range the sensor is looking for.
Personally I prefer the cyl 1 ignition advance pid. Same data but it shows finer detail and it shows advance as positive and retard as negative which seems more user friendly to my brain.
I think the KR pid was updated for that....I need to DL the updated file and clean up my pids.
EBSHO is right, there is something off with the requested boost number as LME doesn't run that high.
I would ask the folks at
scantool.net to swap your pos wifi for a bluetooth free of charge.
I just want to know how you are able to drive without WOT blasts, lol....
