I have recently bought OBDlink SX & OBDwiz to run diagnostics on a 1999 Toyota 4runner 4WD 3.4L gas 5VZ-EF. I installed recent OBDWiz software from the web-site and usb drivers from CD on a windows XP laptop; everything seems to work fine.
After connecting to the car via "auto-detect connection", program shows connection "ISO 141-2 @ 10.4KBaud", lower right corner of the OBDWiz window shows between 6 and 10 PIDs/sec.
I would like to look at O2 sensor(s) voltage at real-time, but it seems that data sampling rate is not fast enough.
Assuming I can use the whole bandwidth for reading only one parameter,
I have selected only one parameter (O2 sensor) on a chart , but it still samples O2 voltage once in 0.6-1 seconds.
Enabling/disabling 'Fast Polling' does not change the situation. O2 sensor priority is set to 1 (highest?).
Could you please tell me if there a way to sample one sensor several times per second?
I guess if transfer rate is 6-10 points per second, it should be good enough to sample an O2 sensor sine-wave with ~1 sec repetition rate.
Is it typical to have 6-10 PID/second sampling rate in my setup or is it an indication that something is not quite right?
On screen-shots from OBDWiz help files, numbers are something like 60PID/sec.
Thank you in advance,
