Adjust for poor track conditions,etc.
The MSBC-1 has the following features: *Six stage programmable boost control. *Useful for street or drag applications. *0-60 psi target boost range for each stage(1 psi increment) *Up to 18 different Ramp settings to control how fast boost is allowed to build.
*Launch stage for drag racing. *Shift input for automatic stage selection for drag racing. *Front panel stage selection by driver. *Actual boost readout during boost control. *2 Analog data recorder outputs-Actual, and target level. *2 solenoid drive outputs-One for an increase boost output and the other for decrease boost output. *Can be used with single or dual port wastegates. *Uses electronic pressure sensor to monitor and control boost. *Will force wastegate to produce preset target boost level even with air density, load, or mechanical variations. *Can be used with manifold pressure only or external pressure source for control.

That doesnt seem to old school to me. It will get the job done no dought. I thought Nelson Racing was in Florida for some reason.
