12200411 - A Few General Questions

[ezobens]

Below is screen shot of the EFI Live '0411 speedometer calibrations. ETC is Electronic Throttle Control. 8K pulses seems like a calibration challenge.

Since I have never played with these PCMs before, I still have a lot to learn.
I know that GM had 2K and 4K pulse VSS but what does that equate to in the table you provided above?
Is that 2K or 4K per revolution or per KM or?
Again, I apologize for the dumb question(s) but I do want to learn about all this stuff.
Thank you for your patience!

40 pulses per drive shaft revolution for PCM's .... 2K / 4K for ECM's
