It was just for the sample. It was changed for the recalls. Before that it was changed at 500 miles and then at 1,500 for a track day.
And I just wanted a baseline since I've had the Arrow unit from the start. Not planning on changing until 3k miles or the next track day.
To add to that.... if my car doesn't show signs of debris that has caused other cars to spin bearings, it should make the case better for the Arrow PCM not causing engine failure!
