misfires in cylinders 1,3, and 4 while attempting a no lift shift in a stock psykotuned...is this a major problem?? or something i should erase and forget?

 

Well misfires are not a good thing... I would get your tune looked at!

I have tuned 2 LNF cars and neither are having that issue... one has been tuned since about 2k miles on the clock

 

i mean it was def my fault and i had no problems at all with the tune for about 1,000 miles until i decided to f*ck up a nls...i drove the car today and it still drives like day 1..

 

Well you asked... I gave you an answer... Misfires are not "OK"

 

It's fine, how many miles do you have on the plugs?

You will get a misfire when you take too long to shift sometimes.

 

More of a problem if you care about your cat

Clear it, it is fine.

It has happened to me.

Try not to suck next time

 

ya ive had mine misfire once engine light blinks like crazy

 

I've never had engine misfires on my tune... even with shitty NLS's!

 

haha i know right i was pissed..felt like a d-bag....and the cat will be gone for a catless downpipe come tax return!!


oh i know they arent ok...i just wanted to know if it was something that would permanently effect my cars performance or something i could screw up and never do again haha


haha that it does

 

i have had the same problem with my car also

 

ok if your car is running and miss fires.....its like you walking down the side walk and your brain just happens to not tell your leg to move forward for its next step.......effect.......face plant. a misfire is never good there might be an issuse that caused it. that might of been a freak accurance happen but,im sorry its never good to have.

 

It isn't a clockwork thing.

It has nothing to do with the tune either.

Happened to me when I was stock

Because it damages the catalyst

That's about it.

Oh worse gas mileage

 

As long as by misfire you dont mean excessive knocking all it will damage is the cat.

 

Ive had it happen to me occasionally when NLS'ing with just traction control off, but not in comp mode or ESC off. Check engine light flashed like crazy, power dies, then the engine recovers and all is good and you are off like a bat out of hell again. Embarrassing if someone happens to be in the car with you.

 

By the way, no one is calling you a newbie at anything so before you PM me, you need to realize this.


I am saying what has happened with me, and stock, you miss a NLS, there is a strong possibility you will throw p0300.

Misfires are damaging to the catalyst and one misfire over the course of how ever many engine cycles does not mean everything is just going to fall apart. I think it has more to do with what happens during a NLS than what is commanded, because we don't have the tables to even see what happens during a NLS. **** we don't even have the tables to change what GM does with the stage kit.

I am not saying anyone is better than anyone else tuning wise, but what I am talking about here is P0300, when you miss a NLS.

Stock

Tuned by God

Tuned by Steve

Tuned by my dog...it doesn't matter.

Misfiring under load?

Yeah, that is the tune or old plugs.

 

i've had that it was real cold out and my car wasnt warmed up yet... thats why mine did it... mine is bone stock btw

 

Don't beat on your car when is isn't warmed up.

 

****'s happened to me twice, from 1st to 2nd, didn't screw up the nls... it was after it was in 2nd gear

 

It is not a big deal it has happened to me. Try to shift quicker

 

I just threw the code like 2 days ago but it went away later that day

 

yeah did the same with me too...havent screwed up a shift since though so we'll see!!

 

yeah i kind of did the NLS with traction on and it bogged into 2nd

 

yeah i kinda sorta was itching my ass when the race started so 2nd to 3rd wasnt too pretty

 

it never did this b4 i got tuned

 

it did it lastnight to me its fine just erase the fault
