no seriously if i show 1 of u some pics could u tell what it is...hell the car is 16 years older than i am

 

Uh no.

I'm actually getting offline. It was fun messing with you but I'm going to go eat some chicken and cash in my welfare check.

 

actually NJ i just went out there and looked at my air/fuel guage and no rev is about 15.5 abd full boost is about 13 roughly IM GUESSING from looking at the guage and what i remember it being at so could be off some.

i appericate it anyways Mr. *******

 

LOL Guess your a/f? Dude...are you looking at a Narrowband gauge that says "Lean, stoick, rich"?

****...you drew me back into your idiocy...

 

okay rich sitting lean full boost.

 

lol so you're basing everything off a narrowband gauge?

This is sweet lol

You realize that lean under full boost is bad?

 

yea i know i got to turn the fuel up on it just kinda lost intrest in it once i baught my cobalt. its sitting so it isnt gonna blow up anytime soon.

 

Right...

I'm hungry and my head hurts from reading your posts (I'm the official second victim).

Enjoy tuning with your narrowband gauge.

 

im not gonna lie to u NJ reguardless it runs lean i havent changed it the isntt "THE ****" but i did the turbo myself when i was 16..something to be proud of in my openion.

 

Dude...Shut up or get off our forum. I thought you were a moron after your first few posts. But THEN you back talk Adam... LOL.

 

yea food does sound good actually. ill post some of thoes pics tonight or tomorrow dunno why hes not back yet.

 

Won't be so proud when your engine grenades...

And sorry but you add forced induction to have your engine run better than it was...not worse. So no, it's nothing to be proud of.

I don't even want to know how you are "attempting" to tune.

HAHAHAHAHA

 

i back talk? what is this 5th grade. lol dude im not gonna have someone bash me when they dont even know who i am and probley wouldnt man up to it IRL. now i was having a "civilized" conversation wtih NJ. LOL

 

A civilized conversation would have to include both parties being civilized...

Maybe you're not that smart. I've been laughing at you since my first post made on this thread.

 

lol i thaught u were going to eat chicken? Poof bitch be gone

u just cant resist can u LOL anyways cya

im not banned yet? crist im tired of typing screw it.

 

lol... this thread was just too much.... I"ll save this one for wwhen I"m having shitty day at work and need a good laugh

 

Now he's a magician.

 

Oh, I absolutely agree. However, the theory is that in two engines, one with high compression and low boost and one with low compression and high boost that both have the same BMEP (Brake Mean Effective Pressure - the peak pressure on the top of the piston crown, usually around 180 lbs/in sq in a high performance motor), the low compression motor will make more HP and be less succeptable to detonation. Why, I wonder? More research is in order - I'll report back with quotes from my turbo books once I find answers.

There is another big factor on detonation: combustion chamber and piston top design. Thin, ridged areas tend to heat up and become a heat source to cause early ignition (knock). Smoother structures reduce this tendancy. Cooler exhaust valves help too. The Ecotec is very good in this respect, which makes it nice for FI - I've read that it's very forgiving, and not particularly prone to knocking.

I'll find out soon enough....

Very good, and valid point. However, there is a trade-off in lag. I'm going to try a low-boost kit without an intercooler (I've had 2 cars with this configuration from the factory) just as an experiment. All I'm out if I decide to add an intercooler is the charge pipe - total cost will end up the same as if I went intercooled to begin with. For sure, such a system is inherently limited. If done properly it works quite well and makes an excellent street driver. But it has no expansion capability without adding the intercooler. BTW, Chrysler sold an intercooler kit and control valve to increase the non-intercooled 2.2 Stage 1 factory turbo cars from 146 HP to 175. They used the same turbo with both with only a change in the boost controller valve (and, of course, the intercooler).

I'm enjoying these side discussions on this thread - lots of good technical info being considered here!

-J-

If I ever heard anyone say that to you I'd teach them how to catch 9mm bullets. Some things are NOT acceptable to me.


Sorry, but this Cherokee grew up hearing "damn injin" way too often - I can't know what it's like to be in your shoes, but I had a little share of it.

We "minorities" stick together!

He plugs it into his butt and what comes out ends up in his posts...

 

You will only want to run up to 5-6 psi on the stock 2.4L w/o an intercooler. Even with one 8-9 psi is about the max that would be safe.

 

Lewis don't waste your breath. He knows all and sees all! Actualy all hes prooved is hes totaly clueless and that hes a racist ass monkey! (Hmmm, lets see how can I hurt a black guys feelings......OH I KNOW I'LL CALL HIM A ******! WOOHOO GO ME!) Squeek dude I was on your side but you done crossed a line! First you ask for help then say you don't need any then you try to flame those who tried to help you and now your resorting to racial slurs? What the hell is wrong with you? Seriously do you have some A.D.D. issues that we should know about? Your beyond help! And from your last post you seem to want to be banned! Its easy BAN YOURSELF! Hell you have our permission to PERMA- BAN yourself! Its easy to JUST LOG OFF AND DO NOT COME BACK! You and your raceist crap are NOT welcome here.

End rant.

 

That's exactly the territory I'm headed into. Although since we will be using a piggy-back to decrease ignition under boost, we may push it toward 7-8 as long as we get no detonation or knock sensor triggers.

I'm not looking to race, just get some go here at a Mile High in Denver. Plus it's an auto, and getting very crazy would mean a peformance build on the tranny so it would survive.

You go, 'lope!

 

What piggy back are you planning on using?
I am planning on adding FI to my 2.4, but was going to try and use the stock PCM.

 

Some on the board are surely getting tired of hearing me say this, but what scares me about HPTune and the stock ECM is that it has no way to "see" boost (no boost pressure input).

One of the basics of turbo theory is that detonation can be moved to a higher boost (i.e., you can run more boost without knock) if you back out some timing under boost. To make the stock ECU do this, HPTune would have to be used to reduce timing over a given range. That means that timing would be retarded even when not on boost.

The best solution is something that reads a boost sensor and adjusts timing accordingly. This was actually easier on vacuum advance distributor cars where boost can be fed into a modified vacuum advance to retard the timing when pressure comes up. With digital engine management, a piggy back can be used to "trick" the stock ECU into backing off timing under boost. I'll use the unit Alpine uses (I'm spacing the name right now...).

Here's a good article on a boosted 2.2 that uses this approach:

I'm sorry I used the "N" word but it was to illustrate what pip squeek was probly thinking. I already talked to Adam about this he called me and let me know the new lows that pip squeek had sunk to and I didn't believe him. Sorry Adam you weren't kidding!

Squeek as far as I'm concerned your just a raceist ass monkey. We try to have discussions that bennifit all the members of CSS.NET but it would seem that concept is beyond your grasp. Adam may not get pissed at the racial **** but I sure do! He's a very good friend of mine and its BS that you think you can talk to him, or ANY other members this way! Call me a snitch I could care less but I reported your little hind parts to the mods so hopefully you'll get that ban you were looking for.

Hmmm, I just noticed how Squeek has no place to even input rep....wonder why? Ohhh hes BANNED!

 

I have heard rumors that HP Tuners is close to comming out with a 2 bar map tune for the 2.4L.
