Yes that makes sense, and actually this is what I remember from the original setup I did on that aircraft. But somehow I don't think it worked in terms of correctly approximating low end performance. We can try though with a 0.4 or whatever BOOST multiplier. The thing I'm wondering though is if the wastegate is working, why was the output 164 inHG at full throttle? It seems as though this used to work. Are the wastegate units inches of mercury? Thanks, Jim P.S. Any chance someone good with nasal could write me a quick script for changing the BOOST value to 1.0 at 20,000FT ASL and then back to 0.4 at 19,999.99FT? I'd try and figure it out, but my time is very limited right now. tia _______________________________________________ Flightgear-devel mailing list Flightgear-devel@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
