What is CmrHisto?

This version of CmrHisto is based off of CoolVanilla's version of CMRHisto at It is a utility that will allow you to easily look at a log from your DiabloSport Trinity, inTune or Predator that you have exported to a csv file using File > Export to CSV.

How does it work?

CmrHisto reads a comma delimeted file and processes the data and displays it in an easy to view format. To view your log in CmrHisto, open the log in DiabloSport DataViewer, and go to File > Export to CSV. For CmrHisto to open the file, you must log RPM.
