KRALH (Klopfregeladaption Lasthysterese, knock control adaption load hysteresis). This adjusts how quickly
timing will be restored as load changes. Value 3%.
KRANH. (Klopfregeladaption Lasthysterese, knock control adaption engine speed hysteresis). This adjusts
how quickly timing will be restored as RPM changes. Value 120 RPM.
KRFKLN (Spätverstellung pro Klopfereignis bei Langsamer Frühverstellung, Ignition retard per knock event
in slow early adjustment). Value is –3 °crank at all engine speeds.
NLLM. Idle RPM.
NMAX. RPM limiter
KFNWEGM (Wiedereinsetzdrehzahlkennfeld, reset speed map). Function of engine temperature and gear;
prohibits the gear-dependent overrun fuel cut by raising the reset speed.
VAVMX/VMAX. Speed limiter
5.7. Section Conclusions: Tuning Strategy
Figure 5.2 summarizes the basic functional areas and modules that a tuner might review when developing a
tuning strategy as discussed in this section. To recap: the objectives of the article were to examine some of
the key maps involved in Motronic operation that might concern a professional tuner and that’s what I’ve tried
to provide here, even if it now seems to occupy the uneasy no-man’s land between a story and a reference
work you would dip into occasionally to check something.
