if i see a drop in knock voltages and a decrease in my CAPS time, ill know why.

on purpose...the submissions need to be screened.

I know it's not very impressive considering an "aggressive" K04 program.

Still got some issues to work out.

Namely my craptacular intake setup and an exhaust leak.

ok, ill definately remember to post it it when i can.

dude, I just did a 2.99 caps, with NOS, and no exhaust... how come it wasn't allowed?

lol, yeah i did a 1.78 CAPS down hill backwards...

finds nearest big hill...

wait a I minute florida is flat... farking a

or make the numbers up. uhh, why am i suggesting this, lol!

Is looking for spikes, or quick changes in the voltage. Obviously since the motor is making much more noise at 6000rpm than it is at idle, the signal will be different. But when the ECU sees the knock voltage spike suddenly, that is a result of detonation. It then retards timing accordingly.

So two cars can have two totally different knock profiles but similar CF readings, simply due to the fact that the motors are making different noises, but only truly getting detonation (voltage spike) in certain areas.

IMO, logging block 020 is MUCH more useful than trying to decipher knock voltages.

seems to be something with cyl 2. on all my logs its much higher than everything else.
