To increase stability the extra bank option may be enabled which by default is
disabled. For most vehicles the additional required processor resources will not
negatively affect overall performance. If the shift light appears to randomly
respond to various engine speeds the DSP sensitivity may be increased slightly.
If the gap between the LEDs is noticeably uneven or inconsistent the DSP
sensitivity may be slightly decreased.
