totally depends on how you wire it.

the best way to wire it is like this:

VPC->SAFR->ECU

the VPC's KV output is pretty dirty...that way you have the SAFR cleaning up the VPC's output.

again, it depends where you wire it.

as outlined above, if the SAFR is intercepting the output of the VPC (to the ECU), you set it for karmen. if you are being crazy and have intercepted the MAP sensor input the VPC you set the SAFR to pressure sensor.
