afr question? - SRT Forums

if im mistaken correct me if im wrong but im assumeing that all we need to make the afr work on the aeroforce guage is the wireing harness & afr sensor for the afr to work all we would need would be this right? if we wired it to connect to the the guage

This is what u need to do dude, Im pretty sure it will work with any other wideband brand as lond it has 0.5 V output.

I hooked up my AEM UEGO to the SRT-4 Interceptor gauge today.
This was very easy, the output from the wideband is the white 0.5 V wire and the Interceptor has a green and a white one, the white one is Input 1 so this is the one I used (could use either one ), then this is what Todd told me to do.
Turn the gauge on and scroll through the menu and select the appropriate analog input which I used Input 1 . You'll go to a new screen which will allow you to enter the conversion (slope = 002.0, intercept = 010.0) for this AEM unit (voltage * 2 +10 = A/F ratio) and it worked perfectly. I can't wait to record my A/F Ratios, I'll let u know how everything worked out later on .

yea but that just cost to much im gonna find a way to have afr without payin over 120$

thats what you will need to do unless you want a narrow-band reading....which is already in the gauge.

the interceptor isn't going to control a wideband o2 sensor; it will only read from the controller.

ok so i might have found a cheap solution for afr on the scan guage i was just messing around on the net and found on this website you can buy a bosch o2 sensor, wireing harness and bung all seperate from them but i was wondering if it would work with the guage

does any one know if that stuff i linked to above would work with our guage or not

^^^ Believe thats the answer to your question. I also thought I could just buy a wideband sensor and wire it into the scan gauge, but it makes sense that you need a wideband controller and then the interceptor reads from the controller.

forcefedjunkie · 05-29-2006, 04:05 PM

This is correct, you need the linear output of a controller to send to the Interceptor gauge. The gauge acts as a datalogger for the 5v output, not a signal conditioner for the raw wide band signal.

thx thats all i needed to know

so this gauge can't necessary take place of the AEM uego gauge itself? because I got the interceptor today and just began to install it, but it rained. but on the AEM gauge i noticed there are two plugs, so this was when i figured that the AEM gauge can not be taken out and interceptor in place of it. is this true?

qwiksilvertrav · 06-03-2006, 02:43 AM

Well if you have the uego controller (which obviously you do), it has a 0 - 5v output that's made for dataloggers which is what the scan gauge is...so there ya go, should be able to take place of the actual aem gauge after you set the parameters into scangauge (slope etc).
But basically just use the AEM uego analog output and input it into one of the scan gauges inputs, configure the parameters and you're set.

so just splice one wire(output) on the aem uego and solder it with the one of the input wires of the interceptor? will this read and show live data? or just datalog? because i don't want to know after the fact once the engine is blown.

qwiksilvertrav · 06-03-2006, 02:14 PM

I *believe* that's the way you hook it up and that it will show live data once you set in your parameters. You're probably better off listening to the advice of the vendor rather then me though, I'm going off what I've read and don't actually have my gauge yet to go off concrete experience.

purekoryo · 06-03-2006, 06:21 PM

i installed the gauge today, and you can not replace the AEM gauge. the AEM gauge has to still be hooked up. however, you can still splice into analog output of the AEM gauge with one of the analog input wires from the interceptor and still read live data, but you will just show two a/f. good thing about this is that you can datalog your a/f.
