Hello everyone,

I'm trying to use the 158U to add computer automation to an engine dyno and I
have a couple questions.

First let me say that the ultimate serial has been wonderful to work with. I was
able to quickly review the samples and get my VS2008 project up and working.

Does the ultimate serial have any sample frequency limits like windaq lite?

Should I poll with a timer or use events to retrieve samples?

I need to get engine RPM. I built a little hall sensor circuit and have tested
it at my desk. Do you think I will be able to read RPM up to 7000-8000 Rpm using
ultimate serial?

I'm a programmer by trade but I'm a little rusty on my electronics.

Thanks for any help with this project.
