Wed, 27 November 2002 13:15 Yep massive difference between 7mge and 7mgte fuel and ignition maps. Fuel is also determined off RPM and TPS. You put your foot down and if the TPS changes over a certain amount in less than the preset time then a "Pump" situation is registered which gives a decent percentage of extra fuel to aid response. A/F tune is also different, the target a/f ratios on the gte are richer to starve off detonation by putting in more fuel to stop hotter pockets igniting before they are meant to. The richer a/f ratios and density in the exhaust gases also help turbo spool because they have a greater force on the exhaust turbine. Lots of other reasons why they run different ratios, that's just two. With the ge they run leaner a/f ratios because cylinder pressures are lower and less likely to detonate also. As for the CAS,I think it may be optical(fairly sure), with teeth cut out of the disc. The ecu recognises these cut outs and the disc has one extra notch to denote TDC. I might be getting this mixed up with another CAS.Ill have to think about it for a bit. [Report message to a moderator]
