I just installed the AEM Uego gauge in my car. The instructions show that if your datalogging it will go as low as 10.0 A/F. The gauge does have a 0-5v output on it.

Does the digital readout read below the led indicated range? Should read out to at least 10.0 huh?

 

just put in a uego single channel controller feeding 0-1 volt single to PowerPC. will this gain anything or confuse computer with semi linear signal of .5 to 1.0 volts versus narrow band .1 volt or 1.0 volt signal. Aim is to smooth mid range where engine runs on closed loop or does it confuss computer. Can datalogit (do not have yet) give access to AFR-voltage tables and can 5volt input hurt Poweer PC

 

I have issues with mine. I measure the voltage going into the datalogit box and its 3.8 rock solid with the O2 sensor unpluged(AEM says to calibrate this way) but when I log this, the voltage is fluctuating from 1.xx to 4.xx volts very rapidly?? Ive tried different poly's and with/without ground and checkd box??? why is my datalogit box making the signal fluctuate like this.
