| :Is there any practical use for the speed sensor on our z's?  Not with a stock ECU. You could probably log shaft speed on a stand alone setup, although I'm not sure why you would use that vs a pressure sensor to control boost What kind of EBC would we need to use the bcsv's? Very excited to see where this goes! I think you could use any boost controller that uses a solenoid vs a stepper motor. The only BC I'm aware of that uses stepper motors is HKS.
