M-Tech kirjutas:
Lisaks avastasin, et "octane plug" oli 91 peal, mitte 95 peal ehk sai see ka õigeks tõstetud.
Ilmselt on asi psühholoogiline aga pill tundub veel mürgisem, kui varem, teravust oleks just kui juurde tulnud.
Samas oleks see loogiline, kuna 91 kütusega võiks nagu veidi malbemat süütekaarti kasutada, kui 95 puhul.
Aga kuna originaal ajusse ma ise sisse ei näe, siis ei tea, kas see reaalselt ka midagi muutis.
Tegelikult on see "octane plug" täitsa vahva asi ning sellega saab takisti maksumuse eest nipet-näpet mootorijuhtimises muuta.
Siin on kirjas võimalikud muudatused.
Samuti on Motronicu ECU-t tutvustavas brožüüris selline asi kirjas:
Octane coding
It is not possible to adjust the ignition timing on the Motronic 1.5 system. However, an octane coding plug is provided to
enable the ECU to adopt different characteristics to suit various operating conditions.
The ECU has been built with several different programs to cater for various circumstances, and selecting an alternative
Octane Plug or setting will trigger a different program. The most obvious change is from leaded to unleaded fuel - or vice
versa, when the ECU may alter the ignition timing and fuel map to cater for the changed conditions.
Simply turning the standard 95/98 Octane Plug to its alternative position will fulfill the alternative condition. Other conditions
may be fulfilled by fitting an alternative octane plugs - such as the 95/91. A number of other octane plugs are also available
and depending upon the Octane Plug chosen, will cause fuel enrichment during acceleration, overall fuel enrichment
throughout the engine speed range, timing retard or an increase in idle speed. However, fitting alternative plugs should be
approached with caution as the effects may be detrimental to good running and economy.Seega pole tegu ainult psühholoogilise efektiga.
