PP2000 does log data, but I too have struggled to make it work as expected and log at a decent frequency (which is the most important bit!)
OBD can log, but you need software to do that. I use PCM Scan (paid for as it's so good imo)
I think Scan XL might be cheaper and less functional, not sure if you can log or just do real-time readouts... I can't remember now.
What sensors exactly do you want to log? Remember OBD and PP2000 don't log everything. OBD does quite a lot, PP2000 even more, but there are still sensor readouts missing in PP2000, ie, no raw values from many sensors, but it will show you calculated internal values.
Ie, I still have a multi-meter with RS232 serial output so I can log the multi-meter output to CSV and then convert the values in Excel to real values and correlate them with logged data from OBD etc.
Ie, log rpm on OBD > CSV via PCMScan and then log rail sensor via multi-meter.
