Well... Tried a known working ECU. Analog input voltage still all over the place. I'm going to borrow another wideband kit next and test that. If the O2 analog output from that wideband has an inconsistent voltage, then I know it is a problem with wiring/grounding on the vehicle. I would REALLY like to have serial logging functioning by the time I hit the dyno in a couple weekends. Calvin?

Im having a similar serial logging problem with an AEM UEGO. Same 10.0 AFR but voltage changes when serial logging. I also had erratic voltage swings when analog was wired to d14(02). I changed the analog to d10(ELD) and the voltage is actually very stable now and its 0-5v. I also had to remove 2 capacitors to do so...pretty sure they were R136 and R138 but DONT quote me on it. Give it a try and hopefully there is some sort of response to how to appropriately get Serial logging working with setups other than Innovative.
