I have a Maxisys Elite, fully updated. Datalogging 03 Ford Explorer V8 in Ford enhanced mode, and looking at only the two front O2 sensors, this tool (and others as well) is so slow that the O2 sweeps are useless for diagnostics. Logs for about 2 seconds, then freezes for about 4 seconds. The entire scrolling divisions just stop for several seconds, then resume for 2 seconds, then repeat. Pretty sure it does it on my OTC Nemisys tool too.

Yet the same Maxisys Elite tool in generic OBD2 mode reads the O2 sweeps just fine without stuttering. Any suggestions?
