CM,
Just curious, do all your engines have remote NV's?
All engines of any size/fuel type ect. have some lag time after making setting changes. Remote NV's or not.
Have you tried side by side testing of lag time with the same engine with both types of NV?
Not saying you are imagining things, just asking what you are basing your observations on.
The reason this all started was Ed Moorman implied that with a remote NV the "lag time" was increased, which is simply not true, and so I was just trying to clarify things so people wouldn't think if they placed a NV "upstream" the tuning, or tunability would be affected.
As stated I have had some looong distances between NV and carb, with no adverse affects, including "increased lag time".
Yes- I have done side by side tests, just to make sure my extremely long fuel line between the two would work.
