SUPRAGTE Forums Junkie Location: North Sydney Registered: May 2002	Re: How does the 7m-gte boost retard ?? Wed, 27 November 2002 04:22 The factory 7mgte ecu doesn't care if the engine is on boost or vaccuum. It means nothing to the ecu. It only meters how much air and its density is flowing through the Air flow meter and puts the corresponding amount of fuel with it depending on load which is set through the TPS and RPM from the crank angle sensor. Ignition timing is set through a pre-determined look up table on the eeprom for anything but "cruise" conditions(eg freeway light cruising conditions). It doesn't use the knock sensors for this contrary to many ppl's beliefs. The knock sensor is only used in cruise conditions. No engines listen to the knock sensor under load as a sensor failure would kill the engine in a matter of minutes. Also there is too much interference noise emitted from valves and harmonics in higher RPM for it to be able to detect real knocking. The ignition is retarded on according to the voltage output of the AFM, TPS output, water temp and of course RPM. [Report message to a moderator]
