I am doing some data logs on my car and it seems as if my knock sensor might be off...

Setup is 08 s2000
AEM EMS V2 version 02v2
Running Pump 93
SOS Novi 1200 with a 3.4" pulley

I am trying to get it fine tuned for 93 first and then tune it for E85 then interpolate the two.

I got a baseline reading of knock at 100 octane already and it showed 0 knock and knock voltage never went above 0.09v and remain constant as RPM went up.

Run the 100 octane clean off the tank and did a 93 run and it showed the same results. I dont think my 93 octane from Sunoco is that good to not show any knock at all...


Here is my 100oct run

and two of my 93 runs

 

to future reference of people with the same issue. It was my knock sensor. It was broken clean off.... probably from me pulling the tranny.

 

Yeah they break off pretty easy. Too bad they're so damn expensive

 

Have u ever had problems with ur boost controller using aemv2 ? I have an 08 and my temp gauge don't work neither lol. Sorry I thought I'd ask here instead of PM for further references also. Thanks if u can help

 

I'm using a SC setup so no boost controller. Maybe someone else can chime in to help you.

I also don't have a temp gauge since I'm using a aftermarket dash with a direct signal input. From what I gather the V2 is suppose to display your temp gauge correctly

 

I am using AEM V2 with MY07. Boost is controlled using a MAC solenoid. I don't think I had any issues with the temp sensor. I will chime in once I get back from tuning.

 

Please let me know! I'm tired of tryna figure it out lol. Does your VSA always show up? As far as I was told idle and low % percent are the ones that can't be fix with aemv2. I had my aemv2 looked at by aem and found "no issue." Maybe it has to do with my settings on my tune?
