I have a e67 ecm from a 2013 ctsv .
in hp tuners what tables control the bypass solenoid on the lsa supercharger.
im looking to control the attached solenoid for a turbo.
i looked at the pin-out for the e67 1 pin is 12v keyed and pin 14 is a reference signal .
is that signal on/off or does it modulate signal.

It's a bit-bang pulse from the ECM for the bypass solenoid rather than true PWM. It also updates too slow to control a turbo. I thought about it myself but decided against it...would be prone to boost overshoots and other issues.
