Ok went out to test A/F logging feature (external)
- read PCM


My external voltage readings, w/o any signal being sent starts off at 3.5V. When I send a signal from my wideband, the A/F values and Voltage values are all over the place and they bear no resemblance to the A/F values showing on my Blitz EBC which has been confirmed to be accurate on the dyno...What could be causing this and how do I fix it? Should I be getting a pretty constant rating vs. a reading that continues to cycle from high to low?

:( :( :( :(
