AEM 1g AEM EMS & 2g knock sensor, knock settings?

[slowgsr]

Hey.. Im using a 1g ems on a 1g but with a 2g knock sensor, which is recommended in the aem forums.

I seen only 1 person post up what voltage levels they consider 'safe knock'.

They claim anything up to 1.5 volts is safe for stock piston/rod motor, but they have tuned as high as 2.0volts.

Right now im seeing just 0.8volts on 25.5psi on 94 and meth, just wondering if anyone has any insight before I push the stock motor more. Im trying to get a good low 11 on pump and stock motor before the built one goes in, and just trying to get my feet wet here.


Whats the best advice, should I turn up the boost 3-4lbs, or do some more tuning with the timing at my current level? I would think, up the boost to as much as I want to run, than tune the timing values?...

AFR's are around 11.3-11.4 I may lean them out to 11.5-11.6. The car has gone 11.7 @ 123mph with a 2.0 60ft, so there's more room. Im also having boost recovery issues.. not spool problems, only when shifting. My meth isn't controlled progressively so im wondering if maybe its causing a quenching effect.

Thanks.

I called AEM before and they told me:

Anything below 2.5V it is not considered knock. No one mentioned for stock piston and rod motor. The highest I seen on mine is 1.3V.

With low boost, log your knock values up to your redline to see your knock noise level. Once you have that data, make your knock graph slightly above your noise level. Are you using "full boostcomp" mode or "hybridcomp"?
