hey guys,

as some of you may know, i installed my nitrous last week...it works well...fun stuff and using it moderately so i dont damage anything, nor get bored of it.

my problem is... before the nitrous install, i had my 2.85 pulley, 60 lb'rs, meth, and custom tune to accomodate the meth (increased timing, reduced idc's) ...was good...my lc-1 would read 11.4 to 11.8 @ WOT...

during my nitrous install, i noticed that my meth nozzle wasnt spraying it properly due to its location on my intake (i could see stain marks where the water would sit- i guess, it was poor placement first time around), so since i already had the intake off to plumb the nitrous jet, i decided to relocate my meth injector closer to the throttle body as well.

NOW, off the bottle im hitting 10.7-10.9 @WOT...guess my relocation of meth jet did the trick! how can i lean it out without getting tuned once more...dont feel like spending more money unneccessarily...thanks!

 

i think i will have this same problem once i relocate my nozzle closer to the TB

but its all good, i will just throw on a smaller pulley

 

Move that meth jet further away from the intake manifold

 

ya, i could...but i dont want the meth mixture to puddle in my K&N intake like it was before...maybe i should go to a 2.7 ?

...or is that asking too much of my blower/engine?

 

stop being a girl roll with the 2.5" ha

 

Running a smaller pulley will not lean your car out. You could use a smaller nozzle to do that though.

 

Your joking right?

 

not completely true...a smaller pulley will push more air in which in return will have more air per fuel...which is leaning him up...



not to mention the heat haha...that will lean him up

 

unless his injectors are maxed the maf will compensate.

he will not lean out.

 

yeah kinda like how i went down to my 2.5" from the 2.75" and put the 7gph nozzle in and ran richer...

 

i tuned him..trust me..he will lean out

 

Oh, he'll lean out with smaller pullies! Getting a reflash is the safest way to go about it!

 

yea if u spray more meth when dropping down...if u spray the same amount and drop pulleys it will lean up..

u guys are forgetting that the meth isnt accounted for by the maf

 

lol yea that was another thing... needed to see his tune.

Bit hardcore with it, were we?

 

they man wants a beast...thats what i gave to him..i guess u didnt see the race he did against a c5 z06

 

DING DING DING DING.... some people shouldn't mess with cars!

 

details....

im a bit more conservative with my tunes, especially with WOT pulls.

 

hey dan....u should get on aim later today..we need to talk.

he has a thread where he raced a z06...lets just say it wasnt the outcome everyone expected

 

I'm not Dan... yet you quoted me!

 

yet meth accounts for the cfm pulled and the maf accounts for the injectors.

it shouldnt lean him THAT much unless it was a very precise tune.

 

You aren't tuning right if it's not precise.... dropping pullies not only increases heat but also leans out the car... if you tune for a 12.2 AFR for a 2.8 pulley.... you swap to a 2.7 pulley and still commanding that same 12.2 AFR without any tune adjustments how would that not lean him out!

 

The onboard computer compensates alot to reach commanded AFR. It will keep dumping more fuel in there until the injectors go static.

Isnt there an adjustment point on the meth to lower the rate of injection per cfm@the nozzle?

 

ur ******* avatar...haha sorry dub

 

so wats the story, wishbones ....

retune or more argument as to whether dropping pullies will lean my whip out?

 

just up ur commanded in pe
