Setting up Knock control etc etc....
Hello, I was hoping I can get some insight on what I'm looking at on my laptop when I connect to the AEM EMS on my EVO. First thing I wannna look at is how knock control is set up. The knock control box is checked so I know its working.
What does this graph mean? To me it looks like the higher you go in RPM's the more likely you'll hit knock.... so on the y-axis, if there is knock, the line is the limit of how much knock is considered acceptable before fuel is added and timing is pulled for a safe measure... is my interpretation correct?
Secondly, what am I looking at here? I'm having a hard time making sense of the numbers in the box.
Lastly when the car is off, and w/o me toughing the gas pedal the throttle % reads like 1.00 or so when in actuality it should read 0%
when I floor the gas it goes up to 98.97% or so when in actuality it should read 100% WOT if the gas is floored. How do I correct/calibrate this? Will my tune be thrown off if I recalibrated this? How do I go about doing it?

EDIT:
Ok so I went outside got connected and followed the instructions. Now everything is perfect.
Me other question is I went to the igntion config menu right below and clicked on it to see what it was. I didnt make any changes though, I just hit the X to close the box. Am I ok? Did I change anything? On the bottom left hand corner of the screen it was blinking red and saying cal changed but I closed out of it w/o saving it. Am I ok?
Thanks for your help

^ no, you need to save the file as another name.
just call them for example: 001_91oct, then 002_91oct, etc.
go to your aem pro/setup/internal logging, bottom left, you'll see "rate", hit the up button till your logging the fastest @ 250/sec
tick "loop logging"
"load @ least": -10.0 psi
throttle @ least: ~75%
rpm @ least: ~1500
vss: 0
under "fast 1-7" i have engine speed, engine load, o2#1, ign timing, knock#1 volts, knock retard being logged.
as long as the car runs ok, i would put like ~2* of timing in the 10-30psi load points, yeah it will be slow, turn your boost down to ~15 psi
find a open stretch of road, put it in 3rd & floor it from 2k-till redline.
do this 2 or three times
stop the car & turn off the engine, turn the key on, go to ecu/download log data
once your promted o assign a name to the data, i recomend naming the same as the cal file, that way when you review the data, you know what cal file you had load without even trying.
export the rpm, knock#1 volts, plot it, take the higher side of the profile, multiply by 1.2 & there is YOUR knock sensor cal table.
pm me if you want me to produce your sensor table from your logged data.

thanks for the info....but logging is beyond me right now.....
but back to the original question i didnt do any harm right when I looked at the "set ignition" menu under configure as suggested in an earlier post?
if you can plug your ecu into your aem & drive your car = log. it's just that simple.
damn, email me your cal file to aby.smfr@gmail.com & I will set it up for you.

BTW BlueEvo8 the tables you asked about set the maximum amount of ignition to be pulled and maximum amount of fuel to be added by the aem. it sets up to pull 1.6 degrees of timing per volt of knock, and add 4% fuel per volt. The restore rate and the last line is how fast it goes back to the non-knock params and such.

when you say "take the higher side", what do you mean? You basically plot your voltage vs rpm, which gives you the normal engine noise. Then your allowing .2 for the knock I assume? Seems like a pretty methodical safe way

WOT I'll email ya my map......shortly.
Before I go out and srive the car hard again I will stop by my local AEM tuner (who's like 10 minutes away from my house) and have him look at my maps one more time to make sure I didnt screw anything up.
edit: WOT map sent
Ben send me your email addy
