I'm working with a viewer for Cipher data logs, but I can't determine what units of measure Cipher tracks events with. I logged about 15 minutes of time in Cipher and I got "Time" data from 10 to 883950. If I subtract 10 from 883950, that leaves 883940 of some kind of time units to represent the roughly 15 minutes of time.

Here's the first part of the Cipher data in Excel. You can see that the difference betweet data points (cells) is not always constant.


Here's the end of Cipher's data, again in Excel. You can see that there are over 10,000 time records in this Cipher data log..


Help...

 

I don't know the answer (I'm sure Uprev would know). Until they answer, maybe you can do a test by logging for an exact amount of time, like 60 seconds. Then see what the units are, and your answer is

samples per second = (# of units) / (# of seconds logged)


From your numbers,
15 mins * 60 seconds/min = 900 seconds

883940 / 900 = 982.155556

Almost 1000 samples per second. But I assume your "15 minutes" isn't exact, so you should measure to be more certain.

 

This is a John question. He'll be in on Monday and I'll ask him.

 

Thanks, Rich.

 

Find out anything, Rich?

 

Sorry, half brain dead.

Milliseconds. Thats why it's non-sequential. Also you'll see the difference between two number vary as the RPMs change. As the ECU becomes busier, the less time it will devote to giving you back data.

 

Thanks, Rich.

That helps a lot.
