[johnblaid]

wait...wait...wait. It now occurs to me that my tachometer does not work.

where does the Vboost computer get it's rpm information?

is there a connection here?

Its the same RPM signal as the tach.

How its routed or gets there I don't know.

I don't know where it is but a user (dingy) has posted a supremely hold plated and "clarified" version of our wiring diagram that might get you there. Its an elementary and not "point to point" but it should help a whole lot.
