Very nice! That has to be one of the wierdest looking dyno print-outs I have seen. Some waviness, ok, but a loopty loop!?

I'm wondering the same. Is his A/F good?

Yeah, that loop is bizarre. It is on the baseline run they did. It only shows up in the power and torque at about 3.5 grand and not the AFR.

It looks like they briefly got off the throttle at 6.5 grand. You have to remember that the x axis is RPM and not time so if you increase RPM then decrease RPM you can get that loop look. If you display the graph with time as the x axis you don't see any loops. I attached a graph with time as the X Axis. It is really nice to have the raw files and the WinPEP 7 viewer as I can view any parameters in the file I want.

It is interesting viewing the file with time as the X value. It shows that it took much longer to reach max on the Baseline run than it did on the final run.
