hello

yesterday i connected the white wire on my aem WB to the S300 analog input connection on the S300 board, so i could view/datalog afrs,

then i went to the smanager analog inputs and in the convertion table i choose aem 30-4100. changes the units to AFR, uploaded the cal started the car and all i can see is volts, not actual AFR's
how can i fix this?

thanks

 

I would suggest using the ecu's actual inputs for under closed loop advanced like D10 (eld) for your primary wideband input to make things easier :-)

 

does that datalog afrs with the d10 input? thats how i have mine wired up and it reads it foe closed loop but i dodnt think it dataloged it.. i may have missed it..

 

i need it just for dataloging, i assumed it will be easier, thanks mtber

 

i lookd back at a few data logs and saw the top graph and switched through the graphs tabs.. under closed loop it appears it dataloged afr volts... so that helps. but not an afr number. i saved a afr/volts conversion chart to compare

 

I not gonna pretend I know alot about tuning, but I ran D14 then entered the AEM specs in the voltage, then set my offset to what my guage was reading, by the way it was an analog gauge
