Read And Write Times

Device	512k Read	1mb Read	96kb Calibration Write	512k Write	1mb write
ObdLink SX	30:00	?:??	4:30	expect over an hour
ObdLink LX	14:00	?:??	1:12	expect 35-40 minutes	14:50
AllPro	15:00 (was 8:00)	25:00 [1]	4:08 [2]	18:20
AVT	?:??	?:??	?:??	???
Xpro, Bluetooth	?:??	5:17	0:37	?:??
XPro, USB	3:00 [3]	4:25	1:00 [4]	?:??	6:12

All times are MM:SS. And they're approximate. And some of them are from my memory, which might be faulty.

Note that 1mb chips have the calibration spread across two blocks, so if you only change one of them, that will cut the calibration write time roughly in half.

?:?? means that I haven't tried it (I don't own an AVT) or I didn't take notes (AllPro).

[1] This should be closer to 2x the 512kb read speed, so it will probably improve with more tuning of timeouts in the app.

[2] This was originally 2:30, then become 3:30 (further evidence that timeouts need to be re-adjusted). CRC now takes 15 seconds.

[3] This was 2:30 at one point, I think CRC checks have gotten slower as the CRC step took almost a full minute.

[4] Was 0:32 previously, again CRC may be the problem.
