Im planning on running a vacuum referenced fuel pressure regulator at some point so Ive added in correction for the BPW and accel enrich. The way its done is basically there is a table of correction factors vs vacuum. The factor used is divided by 256 to get the correction.

My question is can the same correction factor be used for both the AE pulsewidth as well the BPW? IOW, will both the AE PW and the BPW essentially need the same ammount of correction as teh fuel pressure changes? It seems like they would as they are both time for the injector to be open. Sure would make it easy to just have one table for all.
