Has anyone re calibrated the CAN bus configuration for their instrument cluster once the map sensor was installed giving a vac/boost reading back to the ecm? I ask because I hooked the scanner to my 18 SS and I'm able to pull up the vac/boost gauge through the instrument cluster module but there is no signal for it to allow the gauge to stay.
I'll know once I get the Lt4 supercharger conversion completed in the next few weeks. If someone is in the Chicagoland area with a supercharger setup, I would try it on yours to verify.
