Gollum Posted November 6, 2010 Share Posted November 6, 2010 (edited) Do you know how hard it is to find examples of systems like these Tony? I'm sure I'll figure it out, but I haven't quite figured out the best way to control this for street use, that'll be reliable and easy to tune. I tried mocking up a table with turbo speed on one axis and engine speed on the other with the variable being percentage of the BOV opening... I realized after staring at my computer screen for about an hour that it's impossible to tune this without first setting a boost curve, because otherwise I can't calculate what CFM the engine will be using. Anyhoo, I've got a mock engine idea I'm making some tables for, we'll see where I get with it. Maybe one of these days I'll actually build me a megasquirt system, then I can play around coding something up.

Tony D Posted November 6, 2010 Share Posted November 6, 2010 the engineer I met in shanghai has such a system on his Z32, and had electronically brought along all t he manuals for me to review... Unfortunately I had to leave before I got them. I'm going back end of the month, or I'm going to press him t o e-mail them to me. his midrange acceleration has jumped quite a bit, his comment was (as I theorized before I knew someonne actually MADE one) was that he e could keep 17psi all the way off launch, where before he had surge issues. In his words it was 'total PID control just like our machines' what do you get when you have two gearhead engineers working at a centrifugal compressor manufacturer who have a penchant for turbocharged nissans?
