Hi Roger,reread your edited post and makes more sense now.Did you reset the adaptions after fitting each new unit or is the ECU running on the adaptions for the previous units still? If you look at the idle voltage reading on the scope trace prior to revving,the OE units show the induction pulses for the engine as normal.The ECU is programmed to see this,if it doesn't it upsets things.The fuel parts one does not show this(yet to see a internal combustion engine that pumps air in/out without a pulse effect).So problem there before you even get to load testing.
