im still in

 

i dont need to dyno because im still stock
its hard to get ahold of gtpprix >_<
and i keep gettin p0450 or was it p0455

 

i dont see a p0450 but a p0455 = evap system leak detected

 

14 misfires...

 

y'd u break ur car? you never told me where u were gonna be...

 

I used get those all the time don't worry my car was fine

 

i didnt at all. idk if it is the half straight pipe. or what. might be a spark plugs.

 

Is that 14 misfires from a cold start?

 

nope. buttttttt i think i just need a relaod on my tune. my fuel trims are off too

 

u can always reset ur battery and see if it happens again

 

ive resetted the battery couple times. resets fuel trims. but they come back.

ive notice lost in power a lil too. hence a reload tune. or me and rootbeer need to **** with the tables and get some more power out of it. but i do still love my happy lnf tune(courtesy of area47)

 

I think it's the weather change my ltft's are like -7.0 right now

 

usually the colder whether makes u run more rich. in the summer i was 11.4-5afr b4 i took off my tune and 60s i was at 11.2

 

you iz smoking crack cocaine yaah?

Colder Denser air = more boost.. goes lean
Less dense air, more humidity = less boost... richer conditions...

Were you running different pullies when you saw those AFRs?

 

no exact same stuff
it seems like wat u said is opposite for me. when it was hotter i was leaner

 

what size pulley were you running in the summer, and what size pulley are you running now?
were you specifically street tuned for the air conditions in the summer, and your car' s current tune now in the winter?

Depending on seasons, the summer time is usually safer to custom maf tune or speed density tune a car to run leaner without running into detonation
Where as in the winter, conditions can be unpredictable at times and a richer tune is usually made.

Though being in california... our temperatures dont vary all that much unless you live where it snows.

 

i was dyno tuned in 100+* weather.
was on a 2.9 then and now

 

I'm sorry you had to go thru such horrific tuning... on a dyno no less.

Besides the point though... What your saying is a extremely strange phenomenon.

You havn't changed the tune at all since summer? Are you logging these afrs thru HPT or thru a wideband?

 

i always get my tune done at night. when its colder. always

 

Should be the only time you tune.

I'd rather run it richer during the day, then potentially knocking at night.

 

i was looking at it on my aem wideband, also checked the afr on the dyno and my wideband was pretty much dead on. i had no choice in the weather it was so hot that week and they had it almost all week fixing my dp and fake knocking

 

Every time I get on a dyno... I never see accurate AFRs...

You need to get someone to log you in HPT. Thats the only way you'll see accurate afr imo.

 

i hope u dont tune more than ur own car, if u tune at night the air is denser and u can run more timing and fuel
then u run in the sun and knock like a ****, u tune for a hot day and leave it and u wont have anyproblems all year

 

i took off my 60s, dp, stu mod, and tune.
im back to stg2 intake 2.9 and header

thats wat the ppl told when i asked if they could lean me out since i was running richer now

 

smart choice we all told u u couldnt handle the added power from the custom tune finally listened
