To address the carb. & OBD I, carbs are probably more sensitive than any EFI system,and OBD I all had closed loop adaptive learn. GM's Block learn mem.etc.
The GM's & Fords w/mass air systems have a definite advantage over speed den-
sity systems because they read actual airflow in,not calculate it.Also the OBD I's
Open loop idle AND WOT! This takes out adaptability when WE would like most.
The solution for us OBD I speed density users is the adj. fuel press. regulator.
Dial up the press. to compensate for flow improvements etc., and the closed loop
operation will dial back the injector duty per the O2 sensors input at normal drive
conditions, usually within it's parameter's unless you make a drastic change,read
big cubes, super headwork etc. The Grand National guys lived on that method w/
stock system use.You only need a scanner & watch O2 readings at WOT,then adj.
I'm excited to see your progress on this,keep us posted!! :coffee2:
