Thanks in advance.

 

in mm/hg ? what cams Yo ?

 

mm/HG, PSI, whatever, i can convert

I'm running C's.

 

ok..

My idle was @about 900rpm (w/minor fluctuations)

MAP was ~-580 mm/HG (w/minor fluctuations)

Car was cold and just started. After it warms idle drops to around 800rpm.

...hope I did that right

car is a 97 R w/13k. All stock except for JDM DC, 2.5" exhaust/cat.

I'm in UT incase elevation somehow effects that figure If you need anything else lemme know

 

hmm...so if i'm seeing -9.2 psig something is prolly not right...

(~475 mm HG)

Thanks, btw.

 

BLAH, nevermind the figures below are for fuel pressure


possibly.. I was looking for a spec reading in the helms.. no dice.

EDIT I'm kinda new to this concept soo.

MAP= manifold absolute pressure right??

In the helms it does state the following. It's in fuel and emissions sec 11, in the Type R supplement. But right now I'm thinking this isnt the MAP, correct?

just in case, here's the specs

Pressure w/regulator vacuum hose disconnected

kPa (kgf/cm`2, psi)
320-370 (3.3-3.8, 47-54)

soo

kPa (kilo pascals') can range from 320-370
kgf/cm`2 can range from 3.3-3.8
psi can range from 47-54

I'm assuming elevation can't effect that figure because the environment is basically sealed, right?

 

well, my cams could play a huge role in this....the problem is me mostly, cause i can't figure out if I used to see lower readings or not....

i'm prolly stressing over nothing and it's as it always was, and I'm positive I don't have any vacuum leaks.


Ok, found some old datalogging graphs, my idle vacuum used to be -10.4 psi which is about 540 mm HG, but the cam gears were tuned back then...

*scratches head some more*

C's should run around .3-.2

my little oem's run at .5 all day.

hrm.. I wonder if I let the car warm if the values would change.

I'm a definite n00b hear, but if cams could effect this value, cam gears could as well... no?

yes, cam timing will play a role. So I could, technically, be stressing over nothing (and prolly am)....but better safe than sorry.

 

hmm im having problems with my map and vafc too....im runnin s2s2's can anyone help...i disconnect the map and the car still runs....wtf? its runnin way to rich too. can anyone help?

 

-11.5 psi @ 800rpm, stock internals, B18C6 engine.

 

I hope this helps:
