Anybody know?
I've got quite a few dyno logs and just now noticed that at 6375rpm it quits measuring rpm.
Is the "creator" of datamaster still hanging out here?

Its an 8-bit field, with 25rpm per bit.

255 x 25 = 6375

No, I'm not the creator of DM.

Dan,

There is a new version of Datamaster out that will display up to 10,000 RPM. This data comes from the DRP (distributer Pulse Rate) and has no upper limit. The data item is called "RPM16"

There is a beta copy of this available for download at http://www.ttspowersystems.com/ . Scroll to the bottom of the downloads page, that is where all the Beta software versions are.

HTH,

Gary
