wideband reads full lean on start up. Help!!!
setup is my05 s2000 with science of speed aem infinity PnP kit with supplied lsu4.2 wideband sensor. everything was connected correctly and base calibration from SOS was loaded onto ems. I'm using a gauge art can gauge as display. afr would display at 14.7 upon start up and then creep up to full lean on both the aemtuner and on the can gauge. thinking i was sent a faulty sensor i replaced it with one that i know works and yet the same thing happens. the entire setup was purchased from science of speed and was completely plug and play which i triple checked for installation errors. has anyone else had this problem with the sos kit? or just had this problem? any suggestions?
