Thanks Grump, ill see about rigging that up

I seem to be making progress juggling the BPW and ve tables, it feels like
its pulling up to about 5000 now which is a big improvement, which
incedentally was the result of lowering my bpw to115. Only problem now is
that it doesnt pull much past 5000 and according to the o2 (which ive found
is next to worthless for tuning, dont know if it got that way or its always
been) its going lean.. dropping down to .7, its also not so smooth going up
it seems to cycle between smooth and rough coming up the rpm range despite
it pulling what 'feels' to be the same. So now im faced with increasing the
BPW to give me more fuel at the top which of course will mess me up on the
bottom end.  Is there any calculation out there to know what  is the
equivalent percent VE change a BPW change will have? In other words, if I
raise my bpw from 115 to like 125,  what % would I have to lower my ve to
equal the same amount of fuel added prior to the bpw change at a given point
on the map?

Sorry for asking so many questions, if this has been covered just let me
know and Ill go look for it, hate to be a nuisance
