Sure can. There was no improvement. I only got 2 runs with and 2 runs without the ice. Neither of the runs with the ice were very good. I spun the tires on both launches and had slower 60' times. I was hoping to get some more test runs last Sunday, but they cancelled the test & tune due to rain. That was my last shot until spring
So I don't have a good feel yet for how much faster it'll run with the ice.
You'll notice the runs below are very inconsistent. I am not happy about that. One thing I am noticing is that the timing advance varies considerably and might be a big factor. On the faster 13.04 run the timing advance stayed pretty consistent around 17 degrees BTDC. On the slow 13.20 run it was bouncing around between 11 and 17 degrees. I see this inconsistency in a lot of my runs this summer. Can a tune help with this?
