Hi, I just recently purchased an autometer A/F ratio gauge and was wondering where the best place to splice into for the rear o2 sensor. Does anyone maybe have the pin diagram for the s2k's ecu? Or is there a better/easier place.

Thanks in advance,

Jerome

 

You want this.

It has the pin outs and descriptions of each pin. I used it when I installed my gauge.

 

thanks man i see you are running more boost (via your sig) what do you have turbo or s/c and how many psi are you running

 

Comptech Sc currently at 8psi. Moving to 9 and AEM EMS shortly.

 

what are you using to boost at 8psi?
like? what kind of fuel management, injectors? etc?

 

E-manage with 440cc injectors and SARD FPR. The E-manage overdrives the injectors to add fuel with boost.

 

how much did that set up cost you? minus the supercharger and aftercooler?

 

One thing you might want to note, especially since you're moving to the AEM EMS, is that the Autometer gauges aren't wideband gauges, and as such won't give you a really accurate AFR reading unless you're right at 14.7.

If you really want to know what your AFR is (which you definately want to with the AEM), you'll want a real wideband setup. I've owned the FJO wideband and it was nice. I've also heard good things about the AEM one and the Motec one.

Blownjrock - Couldn't tell you what the set up cost me. I didi it in stages, mostly with second hand parts and do the labour myself.

Palsor - Not sure if that was to me, but I'm not using the Autometer gauge. I'll use a true wideband.

 

Oops, sorry, confused the guy at the top of the thread and you.... Just out of curiosity, which wideband are you gonna use? I want to hear some feedback about the AEM WB gauge thing that goes with their sensor.
