Acceleration Runs
Here are the 3 recent acceleration runs. RPM is included.
Overlaying the three, you see the initial 2 second behavior is identical:
With RPM pulled from the video (looking at the tachometer) I can also compare AFR verses RPM for the three runs, even though they occurred over different time frames:
This shows a change in AFR at a particular RPM. This has always been in the data, but now, with RPM, and two different gears, I believe I am seeing the effect of an Emulsion Tube hole being uncovered and the corresponding rise in AFR at 3700-3900 rpm. The engine does not care about gear selection or the speed in which you pass through 3700-3900 rpm. it only knows the vacuum pulling air and fuel into the engine.
On a separate note, look how the time to rpm decreases as the engine gets closer to redline. This engine really pulls hard above 5000 rpm. This is The Reason for carbs.
