Datalogging

Logging the engine data while tuning is very important.

With RomRaider you can log individual engine items like fuel injector pulsewidth, temperature sensors, ignition timing, knock, airflow, etc. When you make changes to your map, you should compare datalogs from before and after.

You can also read the adjustments the ECU learns like fuel trims and knock retard. This can help you get a quick snapshot of how your car is running.
