Merlins Ralliart and EvoX TUNING GUIDE Version K.pdf - EvoScan

MERLINS RALLIART & EVOLUTION-X TUNING GUIDEPower & Torque:Allows you to select whatever units you want the graph to use. While the kW/ Nm selection works correctly, the actual graph will have a large difference in plotsize with the SI units. A graph with imperial units fills the whole plot area.Smoothing Factor:Sets the degree of artificial smoothing of the data to even out the lumps inthe trace. The lumps and bumps are caused by small errors in the time samplingand corresponding RPM data. Longer times between data points yields naturallysmoother graphs, without having to use a high smoothing factor. Don’t use 2-byteRPM in the logs, it gives rise to more errors due to mismatch of the data. RMPshould be either the first or second item in your log, so that it is closely alignedwith the LogEntrySeconds time stamp.Custom Column Names in Logs:Time, allows you to enter an alternate log column name for time stamp.RPM, allows you to enter an alternate log column name for revolutions.AFR, allows you to enter an alternate log column name for air fuel ratio.TPS, allows you to enter an alternate log column name for throttle.Boost, allows you to enter an alternate log column name for boost.The ability to manipulate the column names facilitates importing log files fromsources other than EvoScan. For example, Autronic log or Hondata logs can beaccommodated and graphed.In addition, you can graph some alternate data in the AFR and Boost graph. Anexample of this would be to graph Load in the AFR tab and spark advance in theBoost tab. The application automatically adjusts the scaling to suite butunfortunately the graph label remains unchanged. Still, a very useful feature.REV: 0.K merlin@three.com.au Page 115 of 134
