Logger shows 240 counts of knock?!

[zzzwilliams3200]

I was driving home today and my logger was alarming, when I checked it it was showing split second spurts of very high knock up to 240 counts! I thought the ecu could only read 43 counts I logged a few minutes of this and when I looked at it home I also noticed at other points (not at the same time when it knocks that high) my timing advance will go up to 243 degrees for a split second....weird. Is my datalogger on its way out or could it be my ecu? Thanks in advance, Zach

Which datalogger software are you using?

I'm using MMCd v1.71 on an m100. this morning I wasnt able to recreate the problem while logging. Maybe it is just a bug in the software?

I get the problem when my cable starts coming loose just run through and check all your connections.

I never had this problem before with my old Palm Vx but when I got my Sony Clie it did the exact same time the first night I had it. I was just from the cable coming loose. If you watch, most of your other parameters that you're logging will probably go to 0 when that happens. I just made sure all the connections were tight and it hasn't done it since then.

That was what I was thinking too. Sounds more like a comunications problem.
MMCd 1.7.1 Is Andrew Shinn's unofficial version, it's always possible it has a few bugs.

It's possible that it is a bug in Andrew's version since that's what I'm using, but after I saw it do it the first time I noticed it was happening whenever I moved the PDA so I'm pretty sure it was just a communication problem. It only happened the first night I had the PDA which was almost a week ago. I unplugged everything, plugged it back in and ever since then it hasn't done it one time yet.

Also, I was using the same version of MMCd on my Palm Vx, which never showed the problem.

Hope that helps.
