bradsm87 Posted May 13, 2020 Report Share Posted May 13, 2020 I'm still undecided what would be the simplest way to implement or present this but long story short, I'd really like to have closed loop manifold pressure for targeting boost below the wastegate actuator's setpoint for some zones of the accelerator pedal's travel. An example scenario. 10psi wastegate actuator setpoint. 15psi WOT boost target. If I hit the accelerator pedal to 50%, I'd like the throttle to snap wide open but have it pull back to maintain 100kpa absolute manifold pressure once boost starts to build. If I hit the accelerator pedal to 60%, throttle to snap wide open and pull back once boost reaches 5psi to maintain 5psi. If I hit the accelerator pedal to 75%, throttle stays wide open and normal boost control is used to maintain 11psi. It would of course need a table for default accelerator pedal to throttle angle mapping which it defaults to after sudden pedal changes and go open loop with sudden pedal changes. Maybe have the closed loop control inactive until manifold pressure goes above a bit above atmosphere pressure and only start applying closed loop above that point so that everything below that is still very predictable. I get that there are a shitload of variables involved but damn it would be nice to have the car effectively go full throttle then pull back as boost builds for me! Edit: Actually closed loop probably isn't needed. Using current manifold pressure as an axis or influence by another means for throttle angle would be enough to get that basic control which I'm guessing is already available. I'll play with it in some base maps while I eagerly await the G4X Fury's release. Quote Link to comment Share on other sites More sharing options...
