[DMCForum] Re: Fuel system issues



Sorry Rich -- missed this one among last night's messages.

First: Have you ever driven another D for comparison purposes? PRV
more than adequate, but isn't going to give you whiplash. Could simply
be expecting more than it will deliver. Even new from factory was 8
plus seconds 0-60.

Second: Ensure your CPR vacuum and Lamda full throttle enrichments are
working. DeLo runs fairly lean otherwise (European CPR 8.5% richer
than US import). Do you still have borrowed fuel pressure gauge?

Third: Don't roll your eyes -- why not temporarily bypass Lamda? What
do you have to lose? Only need a single banjo bolt for the return line
and an 8x1mm to keep trash out of lower chambers. I have a spare 038
series CPR you could try too. Would then be metered basically like E
series rather than F.

(BTW: If you try 3rd option and like it, would appreciate a post in
big capital letters retracting all the grief you emission boys have
given...)
