Default Help me Read

On the rpm, it flattens out at about 4700 for about .4 before accelerating again.
Is that my converter flash point?
Is 4 tenths normal?

Thanks

Are you running on a 4700 rpm chip ? The next point up, where it crosses the green line looks like the stall speed .

If I see it correctly that is the flash of your converter.

It might be helpful to see the driveshaft rpm graph with the engine rpm gragh.

I'm in the process of machining the yoke so I can read DS rpm, but I don't have it for this graph.

Yep, flashing at 4,700.

During the 0.4 sec, the output of the converter is "catching up" witht the input of the converter. Once you have driveshaft rpm as well, it will be more clear.

I know the ramp from staging to flash is very slow compared to a car that two-steps.

And it's neat to see AFR going down the track. I think that may be more valueable than flash point and etc.
