730 Low VE entries at idle

[Bob Valentine]

Tuning a friend's car, '69 Camaro, 350/"350 hp cam [unknown spec]", camaro
5-speed, 3.73 rear, TPI w/ '727.   He bought the car like this, came with a
horrible automatic trans cal of some sort - BLM's at 108 across the board.
Has 24lb SVO injectors at 43 psi (no AFPR).  Took a AXCN cal (90 camaro
305/5-speed), set it for a 350 displacement.  Moving the injector constant
to 27lbs brought the BLM's at cruise to 128.   Feels like a different car now.

At idle (750rpm, 50kpa) and decel, had to set the VE entries down to about
42-45 to get the BLM's to 124-128.   VE table jumps into the mid-60's right
above idle.   90-100kpa areas are in the 88-93 range.   No longer kills
mosquitos when it sits idling.

This is what the car wants, but is this "normal" or should I be looking for
something else?  The 02 sensor is a 1-wire, ordered a heated since it seems
to cool off at idle.
