Spark angle spikes

I'm getting a spikes when watching the spark angle in megatune. They appear to be random, and only the spark angle changes. RPM and MAP are constant. I have set it to msns mode in megatune, selected D14 as spark output but have not wired the VB921 in yet. The spike also goes below the lowest value in the loaded spark table.

The MS is a V3 with 029Q2.. I didn't build it, i am setting it up for someone else. It is set up to use a hall effect sensor. Everything else checks out ok on the stim.

Any help would be appriciated..

It appears to be something wrong with the msq. I reflashed and didn't get the spikes with the standard msq. Loaded mine back up and they were there again. So reflashed and have entered some settings and loaded up my spark map and it seems ok.. I'll finish copyina all the settings over and hopefully it will be ok still..
