Who said that K04's on K03 tuning /w Stock fueling is ok?

[mrpeterparker]

Good thing the Giac Stg3- tune and FPR is on the way.

92 octane on 91 octane software
Ambient Temp : -10 F

Red: Run 1 : Unknown APR Software
Pink : Run 2 : Apr Stg2 Rev 5.0 91 Octane
Dark Blue: Run 3 : Apr Stg2 Rev 5.0 91 Octane + Lemmi
Light Blue: Run 4 : Apr Stg2 Rev 5.0 91 Octane + Lemmi

[JMTx86]

Well your a/f's are fine, but I don't remember anyone saying it was ok. What did you expect? bigger turbos same boost tends to make your injectors work harder to maintain the desired a/f. + all that cold air.

[mrpeterparker]

i was being sarcastic.... cause those people do exist..

my Giac stg3- tune + FPR is on the way

Jordan and I thought it'd be nice to have a baseline to compare against.. when the new Tune gets here

Why not just get the FPR and save your money and tweak with lemmi?

[mrpeterparker]

buying a used one ...good deal.. and i'm not going full stg3 anytime soon

and there has to be some added benefit in having a "real" stg3- tune .. to utilize the k04's a BIT more efficiently (one would think) not saying I really buy it all... but if GIAC/AWE push it .. there has to be some substance behind it ..

Yea, money for them

You can make the changes you need w/ lemmi for the ko4's and the FPR, if you really spend the time and slowly make adjustments so you don't F- up you can make your car faster then a "off the shelf" tune. You most defiantly want to get that IDC down.

[LowA4]

I'm puting in my Ko4's in a week or 2 and when I tlked to Jason at JHM, he said that Ko4's would be fine with the stage 1 chip, just keep an eye on the N75. That he wouldn't bother with a stage 3- tune. I am still debating on this.

[Mantis]

My stage 3- tune from GIAC sucks, 1st and 2nd gear are fine, 3rd throttle cuts about 3 times, I have to run a MBC in parallel to cap spikes. Talk to VAST or lemmi your current tune. I would lemmi my tune, but the kicker is that it is a locked Jeff Moss tune.

[mrpeterparker]

damn really? btw.. interesting setup you have there... more power to the a6 2.7t guys =)

what boost are you running when it cuts out?

[Das General]

I ran K04's on GIAC for a good 2 months. No issues. Put down great power too.

It appears APR doesn't adapt as well.

agreed APR is a bit fussey maybe it's that time of the month.

[LowA4]

Jason also said something about if I noticed throttle cut to replace the N75 and it should be good. I'm a noob with the S4 so I could have misunderstood.

Well you can clearly see he has serious throttle cut. As his throttle is cut back to 40 percent.

A TCD would be wise, perhaps a 5bar FPR too.

[mrpeterparker]

i'm guessing my n75 is fine... i'll post new logs.. when i get the tune and fpr

[Shomegrown]

APR doesn't respond well to homebrewing.

GIAC is the way to go. K04's on K03 software works fine on GIAC, espeically the older files.

[Euro-Tuner]

a4 guy here, forgive me...so overall is it "safe" to run KO4's on a stage 1 ECU with no other supporting mods?

keep in mind I'm sure the car wont be babied with that setup so I dont mean "safe to drive out of boost to work and back", I mean safe enough not to blow something with that setup.

TIA, sry for the noob question!

[Blake260]

^^^ I hope so.....Ill be going that route very shortly. Many people have had success with it, but I dont know their habits...

[chaos2984]

i ran ko4's on a stage 2+ apr sofware on my S4 and it was fine. other than sometimes it would over boost. but that was normal just couldnt punch it had to ease into it. Fuel was fine on stock fuel. I had piggie pipes 3in cat back, evo intake, And it ran perfectly fine when in boost.

[Euro-Tuner]

...kinda why I asked

[Mantis]

My throttle is cutting in response to the MAF, when I go WOT I am taking in more air than the tune believes I should, cuts back throttle corresponding to air in. I am running at about 18psi, my MBC prevents cut at the top due to spikes, but the cut thoughout the pull remains. Like I said cuts about 3 times, from 100% back to about 60%.

That's easy to find out if you log the car. If you're not comfortable with logging the car, interpreting the data, and making the corrective tweaks yourself, just go to a tuner and open your wallet.

[diaftia]

Personally if I was going to run K04's on a car without supporting fuel mods I would probably just run stock maps and boost levels until I could get the proper fueling in. Doing things like making sure you don't punch the throttle for fear of over boosting will inevitably lead to detonation in most cases. IMO of course.

[Tifosi]

It IS fine to use K03 file with K04s for "normal" driving, people have been doing it since~2001. You will only get into trouble at high rpms as you will run lean. Many tuners believe that even with the use of 5 Bar FPR (Stage 3- specific program such as GIAC or EPL and maybe VAST), you are still risking running lean at high rpms as the injectors are the limiting factor in these types of situation and not the FPR (Almost all stage 3 SWs, except MTM(?), run on the stock 4 Bar FPR). The 5 bar FPR can be viewed as a band-aid until a proper fueling kit can be obtained in order to run K04s "correctly".

[Mantis]

100% agree with you Tifosi, the 5 bar is a band aid, I have had enough messing with an ill running car. Going full stage 3 once the snow starts to dissappear. My wife has been driving it anyways (not very hard), and if you keep ESP on you can't really boost above 8 psi with our crappy roads re: no traction

+1, Fine means it drives, doesn't mean the thing drives really good! Youll get by, I ran on giac for about a month before I had enough money for a fueling setup.

I don't understand anyone who goes stg 3- on software. You can buy a used fueling kit for 1400 bucks or less. I saw on e kit for 1000 bucks, everything you need. Just save up and go full stage 3. Good luck and welcome to the fun of ko4's! Pretty good power!

[mrpeterparker]

oh the rationale.. is that not all of us are on manuals =)

so we need to invest into a torque converter FIRST before we can get into a fueling setup ... and also ... the risk of running full blown stg3 on the tip tranny is an unproven territory (aside from a handful of vehicles) in terms of reliability and longevity ....

correct me if i'm wrong...

[s47337]

do you guys know if there is going to be any power increasement whan ko4s are installed on stage 1 software with no other supporting mods and if there is going to be any increasement how much?

[kf3506]

actually there was such a person that started a thread in the b5a4 forum that he'll run it that way. When people say it's not ok, he call them stupid and noobs.

Thats nice to hear. I will be going stage 3- soon and i have a GIAC from 2002

[///M3 TO S4]

I guess most of you who are saying it's fine are too dimwitted to see the 150% injector duty cycle................in plain english THAT'S AWFUL, LIKE REALLY, REALLY, REALLY, REALLY BAD. Even 110% on some of those runs is really, really bad....

[mrpeterparker]

i wonder if some W/M will help...

Anything near 100% is bad. when the IDC hits 100 the injectors are permanently supplied with power and they're just along for the ride...With that being said, your logs look good Mr. Peter parker, throw some timing at that bitch

not sure if you're being sarcastic or not =P

but GIAC 3- software has all the adaptation channels locked out.. =(

Yeah, I was being sarcastic about timing. Your car looks fairly safe though. as shomegrown has said, there aren't any documented issues with injector failure, it's just something I'd be paranoid about because I wouldn't risk such an expensive motor. More timing would mean you need air and fuel faster which your injectors wouldn't be capable of. I didn't realize the adaption chanels for stage 3- are locked out though. I would heavily consider a full stage 3 instead of a stage 3-. The bulk of a fueling kit is the ECU file. Other than that you only need $250 injectors and a larger maf housing.

my issue is that .. it's a tip.. i have to do a TC before i can do fueling...

which is some spendy labor...

i just threw ER's in on saturday .. which might've been a bad thing, because in theory there's more air flowing now...

but i'll have an aquamist in soon, and hopefully HOPEFULLY in theory the alky should help balance things out?

wishful thinking

[Caddy7]

How would it be to throw in bigger injectors on this car?

Would the Motronic compensate and lower the injector duty cycle to keep A/F ratio?

[wdbdy2000s4]

the answer is pretty much no. My brother and another one of my friends both tried bigger injectors and they ran shittier then the stock ones. They're both back on stock fueling now.

on what software? 2+ ? or 3-

[wdbdy2000s4]

they were running stage 2, and stage 2+ GIAC. sorry if I wasn't clear.
