can the PCV ignition module advance the timing?My understanding is that the ECU knows which cylinder is inducing based on crank position and snapshots the MAP at the appropriate time to give the MAP reading per cylinder (Rocket III has 1 map sensor tubes to the 3 throttles).
Yes the PCV is spliced into the crank position sensor plug so this must be where its rpm reading comes from. I'd imagine might also uses this for crank position info as the add on ignition module can be used to alter timing (ignition module also has crank input but is apparently not used for Rocket III application)
So with all this info I'd imagine the PCV knows when to snapshot the MAP signal for pressure based fueling
