Scan runs "slow"

[DaddySS]

No, running the scan only.

I appreciate the help. Any other ideas, thoughts????

I'll try it again today and see what I can find.

Further info, it scans fine but when it starts logging it runs behind worse and worse as the log progresses?

Just went back over this thread and noticed that the laptop spec is not listed.

I have a 2Ghz dual core with 2GB RAM and obviously have no problems.

It was working fine up until a few months ago

I think I know why the log runs slow. I recently added all the spark PID's starting 'EST-'.

This took the total from 29 to 44. On the F9 tab, at the bottom left, scan mode is Dynamic for the 29 PID's & General for the 44 PID's.

If the PID's go above 29 with my config, the scan mode changes from Dynamic to General. Under 'Edit/Properties/Logging/Scan Mode', the option Stream Fast is selected. The info box here probably explains in full the relevance of channels etc., but it's been a long day & I'm knackered.

Sliding the bar towards 'Faster' under 'Edit/Properties/Playback' does speed up the playback.

What is odd is that I only noticed the slow logging today, when the same PID selection was used yesterday for both monitoring & log recording.

Oh well!

Yes pids should be kept low for max fps.
It will scan them with more, but it can miss data and as seen go slow.
I learnt that early on. Didnt think about that one.
When logging spark pids, you wont be able to log much else. In fact you may even need to not log all the spark pids to fit them in.

Just to the right of the number of PID's is a number of channels. For the fast datalogging, you want to keep the number of channels at 24 or less.

Under scan mode is at general, I can change to dynamic but not stream fast?
