hers a pic of what my a/f curve looks like. from 12 seconds to about 16 seconds. 3rd gear 3000 rpms to redline. peaks at 12.3 and drops to 10.6. any way to straighten this out?

mods. s1, 3" turbo back, return line kit, wga (21 drop to 15), K&N filter, mapclamp.

several variables...
1. fuel pressure
.....what is your static pressure? if the static pressure is too high, it will be hard for the piggyback to safely pull fuel out. also, you'll have to realize that with a rising rate FPR, on the stock turbo, your A/F will be good in vacuum and low range, rich in the midrange, and lean up top as the boost drops off. if you add enough fuel to keep it safe up top, then you'll be rich in the midrange, which brings us to #2
2. piggyback
....get a better piggyback :lol:
mapclamp=1 tuning point, where you get it as close as possible to your ideal A/F.
piggyback (emanage, dtec, safc, etc.)=multiple tuning points defined by RPM that will allow you to tune out large changes in A/F to get a more ideal A/F ratio.
#3 standalone
....get a standalone, tune it, and everything will be ideal, run better than stock (usually) be more efficient, have more power, more adjustability for future mods, safer, and possibly even better gas mileage :lol:

right now my problem is i'm running rich up top, not lean. up top i got my a/f to hit 11.1 steady. i need to lower the pressure. right now i'm at about 48 psi with the vacuum line disconnected.

if you're running rich up top, then you're running REALLY rich in the midrange. get it on a dyno with a/f and you'll see what i mean. 11.1 is not too rich up top, its actually good to have it a little richer at the top of the rpm range

when i said "lean" before, its relative. with the rising rate FPR, you will run leaner as the boost drops off since the fuel pressure is related to boost

Ya his midrange is around 12 but it drops to 11.1 or so at the top of 3rd

that's because of his boost...

what RPM ranges are you guys talking about???

if its getting richer at redline its because he's using a mapclamp...
mapclamps suck balls compared to a piggyback :thumb:

3rd gear. 3000 to 5800. it will spike up to 12.3 then slowly go down to 11.1 then hold steady at 11.1


mapclamp=$30
piggy back=more then $30 :lol:

that spike is probably caused by building boost too fast... 11.1 is not "too rich" its on the rich side, but 11's are ok.

11.5 is what i would consider a safe/ powerful tune... but that's me :thumb:

i personally won't do 12's, but i have crappy gas, so its up to you :lol:

i dont know, the car isnt pulling well ether though. i raced an mr evo and he jumped ahead of me in a race from a roll. might have been because my tires spun, but it didnt look like i was gonna reel him in too fast. car just seems weird right now. gonna lower fuel pressure a lil bit and lower boost as well. boost has been spiking to 21-22, i'll drop it to 19-20. maybe 22 is just too high with out water injection/fmic. ordering a devils own w/i today i think.

take that out, and you'd be correct :thumb:

also, evo MR's are NO slouch... i've seen reflashed MR's take down big turbos on the highway gearing and weight play a HUGE role there

dres
06-21-2018, 09:41 AM
also with the whole weight thing. i weigh around 250, which is more then most drivers, and i have 2 bowling balls in my trunk, plus about 40 more lbs of misilanious things in my car. gotta clean it out. can maybe make it 100 lbs lighter easy.


gonna lower boost to 19 tonight.

So the 14 flat I ran when I first bought the car shoulda been a 13.9 if I wasn't a fat ass?

i run a map clamp and my air fuels spike at about 21 flat and drop off to low 11's. i just make sure my a/f is around 12 flat at 3k and then let it fall to redline. its all you can do when you go ghetto

dres
06-21-2018, 03:22 PM
ok. i was out for lunch and durring the day my boost is at 19 (what i set it at) at night it goes up to 22? it feels like it pulls harder durring the day.at night i'll just drop it to 19, at 19 in 2nd at 3000 rpms if i floor it it just spins, at 22 its spins a lil.

probably pulling timing@ 22psi... that's just too much on the stocker

dres
06-21-2018, 03:29 PM
total money spent on the car:
stage 1=150
exhaust=200
return line=360
mapclamp=30
wga=60
k&n air filter=10

total=$810
next mod w/i=185

total cost for 300 whp=995 :lol: (if i get 300 whp)

installed everything myself or with help from family/friends, even got the s1 reflashed for free. everything was used except return line and w/i.


i am the king of ghetto modding my car


oh i also have done all my own tuning with a wideband i bought for $40 (rich guy thought a 3 year old wide band was too old). damn it i forgot i did have to replace a few cables on the wide band which came out to 80. crap!

hopefully w/i will save timing, and i can raise to 22

06-22-2018, 11:55 AM
id just keep it at 19 with w/i. 22 is just blowing hot air on the stocker.. you will be slower at 22 than 19 when tuned right... i think???

punkrokdood
06-22-2018, 12:00 PM
on unmodded turbos, i think the most anyone runs with any kind of positive results is 21, and that's with W/I

20 is really about all you can do

yeah. they never have the boost hold higher then 16. they told me i could run 20 psi right now and i'd be fine.

spools
06-22-2018, 12:13 PM
yea, 20 is cool, i only spike 16 and run a bit rich 10.8-11.1.... just cause im always worried about hurting my car. when i go to the track, ill turn it up to 20 and retune it for it at a 12 flat a/f.

22 is effective, but you have to run it at the cost of lowering turbo lifespan. i dont plan on keeping this turbo for over the next 2 years. might as well beat the shit out of it.

Its feasable even with a bone stock turbo. The main problem is the shitty exhaust manifold. We run 23ps and hold 22 in our stock turbo[unmodified] power and mph record holder. Here is a pic of the dyno sheet. We have a bunch more of things being added so I expect the sheet to improve in the up coming weeks. We will also install an EMS to raise the rev limit to 6500. With the cams and headwork on this car, the little bit of extra Revs will do wonders for our ET.
