I had to lower mine to 4.7 to not hit the fuel cut and i also had my map to rich in two spots which i though t was fuel cut but it was to rich there . Running strong now added some timming back in man i thought it was fast before Nick i need to get you a datalog so you can check it out . I still believe -16 degrees is to much out .

Keep in mind that when you lower that number you also lean out the car. So you may need to use more extra injector.

Yea i still got to get some of the 12.9 a/f out and alittle rich spots out / I need to dyno i feel i have a very good tune right now . Should be getting good numbers now . I can make second gear spin at 4500 if i punch it . Pretty insane . Working on a trip to Dallas to give the boost up guys a run for there money . (cheers)

I should have my extra injectors in this week bring it (thumb)

Oh beleive me iam going to bring it . I still not out of stock turbo yet . Did a run with a buds gt pro and pulled a 13.7 at 104 . I have a really good tune . Darkside is makinf me do stupid things .(deadhorse

nick,tim,.........
so far I have not gotten rid of the cut by any means,I went and checked the wiring again,for literaly the 6th time,and no issues.you can see I am running fine,then BAM it jums to lean farther then the 02 sensor can read,then snaps back to normal,then BAM no fuel again.



ok,this first file is if you want to just view the info,and the second is if you want to play it as a datalog.

hey wicked, can you do a seafoam test? I noticed when we did ti-99 turbo upgrade to MPNick's stage one we replaced gaskets etc and now he doesn't have, but a very minor exhuast leak (becuase we over torqued and used old bolts, but anyways we got rid of a lot of the leaking and now he doesn't seen to have those problems he use to have.

I guess he had leaks and they cuased phantom issues, you may want to look at that.

take a can of seafoam and pull thye pcv vavle off and put it back in the valve cover. then put a two-way vac fitting one big end to fit in the pcv hose and the other should connect to a long piece of oild vac line to put in the seamfoam can. Get abo0ut 3-4 friends if possible and two look under the car each side and one to keep the engined revved and another one to look from the top of the engine along with you as you slowely put the vac line in the can of seafoam. look for any white smoke coming out of nay vac line exhuast area ect. If you see anything you have a leak there.... fix any leaks by replacing all gaskets, bolts washers ect and torque only to spec!!!!

alot of people if not everybody ends up over torqueing and flattening the gaskets and then having leaks no matter how hard you tighten...

problem with that though,sea foam only smokes if the engine has any carbon built up,I only have 500 miles on this engine,and have recently stuck a borescope down,and yeah,it's clean.

this issue wouldn't be related to a small leak anyway,it is a problem that only appears when I get to 10 PSI,and the car is still trying to pull,it just cuts,pulls,cuts,pulls.

thanks for the advice though.

I assume the reason you have -5's in the analog tab is to limit the MAF voltage in hopes to keep it below 5v? I can understand that, but you are taking even less fuel out. Have you tried larger numbers in the xtra injectors tab? Did you try the same setup with an even lower upper limit, other then 4.8? Try numbers like this and see if it goes lean.

Man are you sure that you arent to rich in those spots. I had that problem and only two spots leaned it out by 1 or 2 numbers bam No buck i still have it sometimes dependent on how cold it is . But car pulls so f8777 hard now Ima scared my motor might blow. It sreally crazy now .

He did have the analog to where it was adding no fuel and next to nothing in the xtra injectors, so I think he is lean, but it can be possible. In the log, you see it going supper lean and back again.

I am running the -5s in hopes to use more of the secondaries then the stockers,hoping the secondaries cover the gap.


this one I posted is just the latest in the things I havetried,and is the best.
with it,i don't get cut in first gear,becuase there is no time for it to cut,and the harshness is not as bad( but it is still enough to make me not want to boost,especially in second gear,harsh ass fuel cut.)

Not understanding your thinking on this. Why cut the stock injector down more then you need to? Run as much stock injector as you can until you get cut. Then lower your upper fuel limit down until the cut goes away. Looks to me that you are running real lean at the upper boost levels.

I need some help with the mpi. I just installed it on my computer and it says that you have to enter a security key from a floppy disk. I cant get the key saved on the disk. When i go to my computer and try to open the security key it says, windows cannot open this file, windows needs to know what program created it. I bought the unit from a board member so want to know if theres something I need to uninstall for me to save the security key on disk. Sorry about such a beginner question compared to the other topics on the thread so far, but im just learning.

No biggie, all you have to do is move the security key to the mpi folder in

C:\Program Files\MPI TUNER

You do not need to open the key up. All you have to do is move it to the appropriate folder and it should load up.

Let me know if you need any help?

so my point is we all should do a seafoam test and ensure we have no vac or exhuast leaks and if so resolve them. I have learned a very important thing and that is to always replace all gaskets, nuts and bolts, washers etc... when you remove something... And always use proper torque and tightening sequences as well. for instance the exhuast manifold has a special tightneing patteren and you have to tighten in a two stage fashion, once to 8 inch pounds and then you go back and follow the same tightening sequence and use 16 inch pounds, even going out of the spececial bolt tighting sequence can cuase leaks which will lead to phantom problems...

Where does it say inch pounds? The FSM says 14-16 foot pounds.

Just like he said.

You're an addict man. The car has a limit. Gotta keep it in tack if you want to run Jake. (thumb)

will do

 

[apocman]

ok let me look at the document! Oh ok, the exhuast mainfold is a two stage torque sequence the first tightening is at 8 ft lbs and the second is 16 ft lbs. You tighten in this order each time. Tighten the top middle bolt, second from the left bottom bolt, second from the left top bolt, middle bottom bolt, second from the right top bolt, second from the right bottom bolt, top left corner bolt, bottom left corner bolt, top right corner bolt, bottom right corner bolt and finished with tightening the 27mm nut holding the EGR pipe to exhaust manifold...

Where does it say inch pounds? The FSM says 14-16 foot pounds.
