SDS and Boost Control

[mdb4879]

Hey guys, I just have a quick question about SDS. Can it also be used as a boost controller? Like, can it control a solenoid to actuate the wastegate? If so, can it vary the boost at different rpm levels and limit the boost as a percentage in different gears (if there is a way to tell it what gear you're in, like by a function of speed relative to rpm)?

Basically I have two thoughts in mind by this. First, on the dyno one could vary the boost at different rpm's to maintain a flat torque curve (once there is boost of course). Second, if the ecu can know what gear you're in then it could limit the boost in any particular gear. So one could go for a drive and floor in in first and dial down the boost until the wheel spin is not achieved, but the tires are almost at the point of losing traction. Then do the same in second gear and so on until full boost is reached without wheel spin. And by limiting the boost as a percentage mean the parameters already set for a flat torque curve will be maintained.

This is basically what the Mazdaspeed 3 does for those who are familiar with that (idk if the Speed 3 does the flat torque curve part, but I know that BMW's do and the Speed 3 has a boost limit in first and second gear). So basically I guess this could be a form of traction control, allowing one to accelerate at pretty much the same rate, and faster than with wheel spin, in the first few gears by maintaining the static friction between the tires and the pavment (static friction is greater than kinetic friction, when the tires are spinning in relation to the road).

Unfortunately "No".

Alrighty then. Thanks for the quick response.
