O2 sensor signal - does this look ok? Does the O2-sensor signal in the logfile look ok for a cold start and then going in to closed loop?

Looks reasonable. Log commanded A/F also. In open loop if the commanded is richer than stoich they will be above 450mv. Once it enters closed loop they will oscillate both above and below 450mv. The low point they oscillate to looks pretty good. The high point they oscillate to could be a little higher in the 850-900mv range
