Wondering if i caoulld get someones map to start out with. I just got the AEM with uego built in. I only have a 3 inch turbo back exhaust no cat for mods. I was also wondering how the aem knock sensor and timing retard work due to knock? I know the aem has individual cylinder timing retard to control knock. Does anyone use this or does it require more sensors? I dont see why using someone elses map would be bad if it had this function. It would be like using an xede right? every customer gets the same map?

 

the ems comes with a base calibration that should run the car good enough to get it tuned.

 

Using the same map kinda gets you in the ballpark, but you will still want to tune it to your car. Ideally you start with a CAL file from a car with very similar mods to yours, but you won't know if they tuned it right either.

I think your best bet is to find an EMS tuning specialist in your area and have them set it all up. Then you can fine-tune it from there. It is a lot to learn all at once if you are doing it all yourself from scratch.

To answer your question specifically, the EMS by default has per cylinder knock control. You first need to establish the knock noise threshold for your engine, and then the EMS will consider any noise over that limit to be real knock and then retard the timing and/or dump fuel or whatever you want it to do at that point. You can see which cylinder is knocking at that moment by looking at the Parameter called Knock #1 Tooth, and of course by logging that parameter along with your other parameters. It does all this with just the stock knock sensor and it works well.

When you get it set up, go to the AEM EMS forums and there is lots of info there about how to set up the knock noise threshold table, and what all the knock options do and so on.
