One of the things I concluded fooling around with the MAP filtering was that = it seemed to need about 3 cu. in. of volume (line plus filter, or whatever) = to act as an effective “spring”.  Have you estimated how much = volume you have?

 

I never tried to = figure out the volume of the tubing, partly because I can't actually remember = how it connects behind the firewall.  I have two lines running back.  Originally, one went from one port on the TWM to the A controller = and fuel pressure regulator.  The second went from the other port on the TWM = to the B controller

 

I also had = two lines; one to each of the two controllers.  Now one of those is the line = back to the FP regulator, after the filter.

 

On second = thought, keep up the good work, so I won't have to do any of this = :-) 

 

Thanks; but = “sorry”.  I’ve done all I’m going to do on the MAP filtering.  I’ll be = happy to learn from your transducer traces.
