Hondata

Personally, I think I am consistently running rich no matter what I try because I probably have a fuel rail off my old accord or some other honda instead of the prelude h22a motor I am using. I have tried changing a dozen settings and adjusted fuel a dozen times...still rich 10's.

But for the good of all, PLEASE post your vehicle and its stock fuel pressure. Smanager needs this information to make fuel compensations. (??) As I said, I am particularly interested in the Accord and Prelude stock pressures for comparison, but please post ALL relevant information!!

Gratefully yours,

B18C1, built with internals at 11:1 CR, Stock GSR cams, S300. Fuel pressure is 36 psi at idle with vacuum, and about 44 psi with out vacuum. I believe this to be the recomended range for the majority of Hondas with stock injectors, fuel pumps, ect. Air/Fuel of 10:1 is SUPER fat. Unless your fuel rail is a returnless type causing a "dead heading" symptom or its clogged, I would look else where for the high A/F ratio. Humm I smell some diagnostics in your near future.

What set up are you running?
