well i got 440 injectors and my safc was able to lay down a 12.0 afr on 6psi, but i am getting detonation(yes i hear it) right when full boost comes and every time i shift to the next gear it sounds like rice crispies going off or even rocks hitting under carrage but i know its knock/det

im leaning more towards it being caused by high egts and my afr is decent its 12.0


my setup
to4e 57trim .63 a/r
treadstone manifold
38mm wastegate
2.5 inch downpipe
2.5 inch spipe
stock midpip
ebay muffler


my thought is that maybe the stock midpipe and ebay axel back are caused too much restriction thus increasing EGT's

tomorrow i will see if i can get around to removing the exhaust and running open spipe

maybe this will help then again it will prob make me run leaner =[

btw im on safc so still on stock timing map

sounds like you neeed to get a professional dyno tune at shop or engine will go bye bye....

cburglb34

lol dont worry i know how to tune thats not my prob my problem is the high egts and me maxing out my safc....i need a aem fic ASAP


i took off the exhaust and i instantly noticed a huge difference in 4.8psi


right now 4.8 psi feels like 6psi


and my afr is like 11.5 on 440s with no adjustments

Timing?

cburglb34

yea i was thinking timing but ppl dont mess with timing usually till like 7psi but all will be adjusted for when i get AEM FIC right now ima run 5psi and open spipe

ElevationTC

Alot of people who are not pulling timing at 7psi are no running 7psi, there sweeping through it.

so there running 9 and since passin 7 so quick its ok.

On a car running 7 psi you probably need 1-2 degrees pulled

Pull a little timing. Well, get an FIC, then pull timing. Intercooler or no?

cburglb34

oh so they are like pulling timming when they hit 9psi and not on 7 since its so fast that egts dont really effect that...hmmm interesting...


i wonder how deatch by tc managed to get 12psi outta his safc....prob had large injectors and return fuel so he can keep things uber rich/cool

cburglb34

YES INTERCOOLER lol

Just asking. I know plenty of people who run no IC.

cburglb34

haha yea i know what ya mean, i used to run no IC on my other turbos but decided that if for somereason a fin on my turbo breaks off it rather it land in my endtank and not my intake manifold LOL, and also dont like the thought of heat soak

I was gonna say you may have been seeing excessively high egt's due to no IC and restrictive exhaust. But no dice.

cburglb34

yea, oh well tomorrow ill go crank boost to a flat 5 and then leave it at that till money comes my way and i can pull timing

buy my zpi 2.5 mid pipe. that should help with exhaust flow and lower them EGT's.

tC_litigator

You're running a blow thru setup right? Did you notice any detonation before you went that route? Also, what's the diameter of the pipe your MAF is in?

cburglb34

running a blowthru, its in a piece of 2.5 inch exhaust pipe and i havent thrown a code for that, but anyways i never tried 6psi with a draw thru, and actually with a drawthru i would have maxed my safc out at just like 4-5psi

Piggy backs and controllers FTL. Tuning just the AFR is not considered tuning a vehicle. Theres a lot more to it than that.

ElevationTC

Piggybacks are accually top notch now a days!

The aem fic, works so flawlessly with oem ECU!

ive been standalone for 20k miles

tC_litigator

you're kidding right??
