It seems like direct fire its the way to go in the near future
Yep i will start with the datalogging and check if it works
For now i have a small readings from sensor 1 and baerly non from sensor 2 , but i will test it better later today
Thanks for your help again!!!

Nope it reads only sensor 1
And is a ecu problem i invert the pins and stills read only knock 1
I have sent the ECU 3 times to AEM to solve similar problems

I don't know if there have been any updates since then. What color is your ecu? and the serial number? The series II comes with a good base map. If you provide me with your current calibration I will convert it to the Series II file for you.

Mine is grey aluminun
Its the firts one , but they uptdate it probably 4 years ago
I found lots of problems with it , they solve (at AEM) moust of them but there is still some that i have notice along with my car getting build.
To be fair i can live without the VSS and the knock sensor 2 , but for sure i will update it in the near future for the series 2
Witch are the advantages of the new one?
Sorry for the silly question but does everything works on the series 2?

I had a very similar problem and contacted aem numerous times and we found that the knock 2 pin input pin location wasn't correct. I'm at work now but will check my notes when I get home to see if I wrote it down.

I've looked everywhere through all of my aem notes and couldn't find anything as to what the correct knock 2 pin is suppose to be. Unfortunately the car I did this on is 4 hours away and the owner isn't capable of tracking the wire down with a volt meter. However I'm confident that if you give aem a call and tell them the problem your having they can lead you In the correct direction. When I found this problem they actually told me they were in the process of correcting the pin out diagram as they spoke, and this was a couple years ago. Good luck

Thanks for the info guys. I finally received my Series 1 back from repair and had much better luck on the dyno.
The Knock 2 as specified in the documentation is definitely wrong. Someone at AEM is trying to determine the actual pin for me. Funny thing is even though we are getting a reading form Knock 1, it is very low and barely shows any activity. I know I am on E85 but the Power FC knock activity was very apparent.
Is there a average knock voltage that I may compare my knock activity to?

Yeah I was having the same problem with mine. Just like eb said you'll have to recalibrate that to fully utilize the knock control of the aem. On my own car I actually traded out the factory sensor for a 5 volt knock sensor from another car and have had a little better luck. When I set it up I had one factory knock sensor and one other and would do logs with both at the same time to find the comparisons for what knock noise was exceptable and what wasn't.
