Has anyone on this forum been able to use the A/D input on the Moates APU-1 for recording WBO2 data along with the PCM stream of data? Or, is it more appropriate to attach WBO2 0 - 5 vdc output into an A/D channel within the PCM that is to say into the Linear EGR analog input? Which is the easier or which is the more robust or appropriate? Hopefully the seasoned TunerPro guys will answer these questions. Please advise. Thanks.
