I have an ais stage one setup on my veh. I am running about 19-20psi on my tune. I am spraying about a 30%meth/70% water (aka -20 washer fluid). I have verified the pump is pumping fluid from the jet. I have the pump set to turn on at 10psi. when driving I feel no change when pump is on. which may be ok but I also see min. if any real change in my a/f. so my questions are, should a run a high level of meth? should I start playing with timing and see or is the lnf automaticly pulling fuel to get the a/f I am commanding?

thanks in advance!!!

 

not gonna change anything if you dont lean it to whatever you wanted it at + increase the timing. Hell it probably would slow it. I run 60/40 mix personally. meth/water

 

PhantomSS do you have a SS/SC or SS/TC?? And what mods...?? Your mph is awesome..How much timing and air/fuel you run with the meth???

 

Do you see any IAT changes?

 

ss/sc 2005

Thats actually my low mph.... most of mine are around 112 now....but crappier times.

11.9 afr
25.5 degrees timing

im not familiar with what is safe for the lnf since they have a different head entirely. You could probably get away with 12.2-12.4 afr since your not trying to bandaid your #4 piston like us LSJ guys.

Infact im thinking about messing with the 12.0-12.4 range

 

I'm running 26.5* at redline on a 50/50 methanol mix.

 

i noticed i was hitting 27.5 but i dropped it a bit because i heard you dont make power after 26 degrees

 

why would I lean the a/f out when its hitting what is commanded in the table. If I command 12.1 a/f and spray met/water I should see a drop say to 11.5 on the wide band right? and once this happens then you make your changes. right?

 

Vern,

Are you running a single nozzle or did we set you up with one before the turbo and one before the throttle body? Also, where did you mount your nozzle at?

Next, I would add some more meth to your mix. Run 50/50 and then see how A/F reacts. You should have seen a slight drop in A/F with the windshield washer fluid. These A/F reading your mentioning. Are they at wide open throttle?

As for IAT's. Your not going to see much of a difference right now because the air here in Columbus is in the 20-30's. Even if you make quick pulls on the dyno that front mount air to air intercooler is going to stay really cold with the weather we have now.

My question. Is the lnf computer pulling fuel automatically? a quick way to tell is to run pure meth and go with a slightly bigger nozzle to see how the computer reacts to it and if it does pull fuel.

What sorta meth mix should I expect from a -45 Windsheild Washer Fluid??

 

If you want to know exactly whats in your wind shield washer fluid that you are using. Look up the MSDS sheet for it online. This will tell you everything that is in it plus the percentages of each.

 

I am running a single nozzle right before the throttle body. I will not see a drop in iats because I am spraying after the sensor. I will try a larger mix of meth

 

sounds like non-methanol mix of washer fluid.

my AFRs dropped 1.5 without leaning it with a 50/50 mix. But yea, tune after the dump, should change your maf curve.

 

You won't feel any difference... you should see your AFR hit what you are tuned for... now my car is TUNED with meth so my AFR is what i'm commanding + Meth...

Now if you aren't tuned for meth meaning you have it but it isn't added into the tune equation then you should see it run richer at WOT than normal...

So for the sake of argument you are tuned for a 12.0 AFR at WOT without meth, you add the meth kit on... you would see like a 11.8 (not an actual number)... but if it's added into your tunes equation then NO you wouldn't see any difference in AFR!

-20* washer fluid is NOT a high mix of methanol... I use 2 bottles of yellow HEET per 1 gallon of the blue ****! Making in a round about way a 60/40 mixture

 

where would I find this heet stuff

 

walmart, auto part stores.... make sure you buy the YELLOW BOTTLES not the Red.

The yellow bottles are 100% methanol....

 

cant find -20 washer fluid....just +20 here. fricken sucks. home depot is my friend on the paint thinner isle.

 

get boost juice from Devils Own, or add 4 bottles of HEET per gallon

 

thanks I will try in a day or so and post!

 

yea, may go that route since 15.00 gallon denatured alcohol is pissing me off.

 

You should deff see a dip in AFRs when the meth kicks in AS LONG as it's not already factored into your tune....

Me I can't tell a difference because it's added in my tune!

You shouldn't use denatured alcohol anyway... most turbo and s/c cars your main benefit from this is the cooling... and then the added fun of a higher octane!

Your just getting high octane.
