jcsbanks just found the min load for knock control or whatever it will be called. I think if we find out where in the process of knock control this table controls things we should be able to do the subtraction method without the large decay rate causing problems. I think that the table he has found will cause both knock, and decay to basically read "zero" and thus their would be no decay to build up.
At least, on my DSM, when I raise the min load for knock control, I have no issues with decay after I go above the min load for knock control.

yeah the decay variable definatley works.
<table name="KnockSum decay timer" category="NewMaps" address="1384" type="1D" scaling="uint16"/>
Should be a value of 160, I halved it and my knocksum decremented twice as fast.
I will look up some other ROMID's when I have time.
I am still thinking my knock-ignore patch will have some use - even when John has found the knock stuff. Because I doubt the stock code has the ability to target a specific RPM + LOAD point.

John's table will take care of all the phantom knock cases where the car is cruising and all of a sudden 36 knock counts. I've been doing it on DSM's for years and its a great feature. As the cars age this will be a necessary mod.

It definatley has a use. It would just be kinda nice to not have the decay variable in their. To be honest though, I am only going to use it on a stroker motor of a friends that needs 3-4 knock sums ignored throughout the whole RPM range. If/when the knock goes higher than this the decay pulling even more timing should just be a note to the driver "hey jacka2s lift, we got some knock going on here". My personal car, I don't need this stuff......yet.

If you getting 36 counts of knock at low boost you have issues. I can understand fixes for part throttle driving, or ignoring a couple counts at WOT due to extra motor noise. However pegging the knock sensor under slight load is typically a mechanical and/or electrical malfunction on the car, no code is going to fix that. You can't simply ignore 36 counts of knock.

Yes it is also knocking if I rev the motor up also, seeing about 9-12 counts.
any ideas? Maybe something sensor related?
