Hey Mark,
Been a busy weekend. Got a couple logs to check out if you want.
I have not gone over the "tobowl" log, but I do remember the knock counts being higher than what I expected, (about 25 or so).
The "tohome" log was not too bad with a total of 8.
I'm probably hung up on the knock counts, but I think it's because I am still confused by how the counts are being reported.
If I understand correctly, everytime there is a knock via the knock sensor, the accumulator increases by one. When the accumulator makes it to 256 counts, then 1 count is reported from the ecm to TunerPro.
Is that correct? If that is, then wouldn't 255x8 = 2040 total knocks be bad? I don't recall hearing that many, if I remember any at all.
Also, I see that quite a few of the knocks occur during the 3-4, or TCC lock up when the monitor shows the RPM's dropping from about 2700 rpm down to 1500 or so. I think it's one of two things. Either the TCC lockup is set too late or I am having tranny problems with the 3-4 area of the tranny.
I think it's the tranny and am waiting for pricing on some parts.
