[Diy_efi] BPW vs VE tables

[Jim Butterfield]

Sorry ski, ive a 3800 series 2 engine and we have a
MAF sensor. we just unplug it and drive a while and
the computer adjusts then we take a scan and see what
the  LTFTs look like go from there. Ill be in the same
boat as you when I get my TBI setup on my old
International scout II...
