i know that hf crx's only have 45lph pumps where normal handa pumps are 70lph, my question is do 92-95 cx hatches have that same bullshit little pump? if so i think thats why i keep blowing up motors, with a conservative tune.

 

chuckle...

i am sure you are monitoring these conservative tunes with some sort of wideband reading eh?

 

now that i have gotta my typical, and expected hmt love. does any know about the pumps? the tune is good, the same one that was in my other car for about 2 years.

 

what xenocron is implying is that if the fuel pump wasnt keeping up, then the tune would be no good, because you wouldnt be able to keep fuel rich enough to to lack of maintaining fuel pressure.

 

engines can go lean for a number of reasons...failing fuel pumps is one of them. fully functioning fuel pumps is not one of them...

best thing to do...if you hear marbles in your engine...LET OFF

 

i love marbles...

 

gota 92 cx hatch also... leans out rappidly... think we share a common problem lemmy guess yur runnign a b series and it leans out and booms

 

no i got a built d series, i put a 255lph walbro in it, and now it is a solid 11.8 afr now!

 

i might need something like that... grr... anyone know whut a stock 350z fuel pump puts out?
