Common Mistakes to Avoid
Common failures come from choosing a tool whose workflow model does not match ECU control needs, measurement repeatability needs, or the available instrumentation pipeline.
Buying for editing when the real need is log analytics
EFI Analytics provides the run-to-run overlay comparisons and session-filtered diagnostics that map changes to AFR and behavior trends.
