Corrupted datalogs, but engine runs fine.

[Nigep]

I have a very odd issue.

I`m datalogging to a laptop,. Using Tunerstudio, via Serial lead to 9-pin socket on the laptop.

The car was running fine, no misfires or other problems, however, when looking back at the datalogs, it`s peppered with 1,000`s of `MARK 18817 - Manual - Sat Mar 07 11:33:08 GMT 2015` comments, but obviously the time / date changes.

Any idea what is causing it ? how do I fix it ?

I`ve attached a typical datalog (had to .zip it due to it being over 1,000k)

Should this be in the Megalogviewer section ?

A manual mark usually means you've hit the space bar.

It could be some vibration causing the spacebar to activate ? But there are over 18,000 Mark`s in that log, many between a single sample. !
