i just got a brand new AEM UEGO for free and about to install it into my car.... there are calibration or like adjustments behind the guage to change the voltage.... now i'm replacing my o2 sensor with it for the time being and i need to conect one of the wire to the ecu. its probably going to be coming out at 0-5 unles i adjust it back to something like 0-1. question is... if i adjust to to 0-1, will my guage be off or not reading correctly like another number instead of 14.7 or like if i kept it on 0-5 volts, will that throw off my ecu and make it put more/less fuel in.... i'm alil confused and just doin a lil research be4 i put it in...
