The chart scale is logorithmic on the y-axis ... so between 1 and 10, the divisions are 1,2,3,4,5,6,7,8,9, and 10, between 10 and 100, the divisions are 10, 20, 30, 40, 50, 60, 70, 80, 90 and then 100, from 100 to 1000, the pattern is the same.
When I get the RPM's hooked up, there will be another section, 1000, 2000, 3000, 4000 etc between 1000 and 10,000.
The temps are in F, AAT and FIT in C.
The logger stores data in hexidecimal format (memory savings) and the calcs tab in the spreadsheet makes the conversions through formulas derived from the circuit I designed. I calibrated the system with a pot of boiling water and I'm only off 1.5 F at 212 F (100 C) when the pot is boiling.
I'm off to do another run now !
