i use datacat to log the analog output of my aem uego wideband (i only have 1 sensor in my drivers side exh)
i plug it into the air conditioning press sensor.
datacat will then convert that to afr (it has an option you turn on). Obviously you cant use a/c when doing it this way.
Other options to display afr include thru oil press and oil temp sensor.
It displays afr alongside rpm, tps, map, spark advance, etc

Hey dizwiz, thanks for the reply, did you ever try the same thing using Tunerpro and the Autoprom to add the AFR data to the Autoprom data stream?

i used To use tunerpro for tuning but not data logging
i used to use tts datamaster v351 for datalogging, and would ‘hand calculate’ the wideband afr off the ac pressure (i had figured out a linear regression formula off it). This was a PITA when on the dyno bc it took time to do and time is $$.
i stopped using datamaster when datamaster stopped supporting it.
datacat is nice bc theyve already done the conversion and give you 2 other options as well for additional wideband sensors (oil preasure and oil temp)
