it seems 'pump shot' isnt a thing that needs as precise of calibration in a sequential port fi system, since the fuel is right there, not way up a wet manifold.
There still needs to be an enrichment. The early ecm's used separate tables because response time of the ecm would not provide rapid enrichment. I was looking at one of the aftermarket ECU makers' manual and found a bit about calculated enrichment based on air density change. I believe it was an option, and it was probably an Accel unit. I remember it because they described it well enough that I thought a person might be able to find a similar calculation in $EE.
