Running a 2056 with Ljet, 9550 cam, 50mm TB, and 9:1 CR. Getting just over 15 mpg. Plugs look good, slight tan. Thoughts?

Just checked the Z injectors. 185cc for non-turbo 265 for turbo.
Clay, it looks like you might be wrong... (all of us are wrong at some point) The whole "swapped in one day and saw a difference in the WB" states they must have been different but if Woki's list is correct (and it looks like it is) there is no way ANYONE could see the difference between a 187 and a 185... Maybe your 914 injectors were restricted? Be way weird to have all 4 with the same restriction level. Geezer, back in the Z car world we used a air bypass in the AFM to set idle fuel enrichment. My 75 914 AFM has this adjustment in it as well. 16 at idle is too lean for my tastes. Normally idle was .5-1.0 richer than cruise which helped smooth idle out. After you get base AFR set with the adjustable pressure regulator (it sounds like you are close) mess with the air bypass at the nose of the AFM to richen it up a bit. I'd want my average cruise AFR to be 13.5-14.5 and my idle to be .5 richer. Does it idle high and hunt now? I would expect it too. Here's a list of a bunch of injectors. some information is missing (like the 914 cc data) but it is a fairly complete list. http://www.atlanticz.ca/zclub/techtips/inj...s/injectors.pdf |
