Review: Motordyne E370

Here are the same runs plotted in their respective groups and a little more clearly.

These are the spark timing and A/F tuned baseline runs. They are inconsistent and lumpy which indicates it was tuned to the power limit and running on the edge of ping.

These are the A/F only tuned Shockwave))) post dyno runs. A near perfect overlay. They are very smooth and repeatable. If these runs were tuned in the same manner as the baseline runs, it would have made additional power.
This is actually a perfect tune. Although more power could be made by advancing the spark timing, you don't really want to push it beyond what you see here. The engine is very happy with this tune.

Here are both sets of runs overlaid. This shows the relative difference in set to set repeatability.

The pre and post dyno runs were in different states of tune.
