Lemmiwinks Help

[Oricle]

Does anyone here have any experience using it? I'm trying to lean out my idle for starters and no matter which settings I change it is constantly at 10.68:1.(will fluxuate obviously but in that general area)

[k0mpresd]

you need to post more details about your set up.

you need to post more details about your set up.

Here is the problem I'm running into. I had stock 282cc injectors with a 5 bar FPR. Which flows at about 380cc IIRC. Went to 550cc injectors with a 4 bar.
ECU wont adapt enough to put it at 14.7 so I need to find away. I'm running a GTRS.

Will messing around with the control bits in lemmiwinks lean out the idle?

[k0mpresd]

no. well, not in the sense you are looking for. you can only do startup fuel with lemmi. you can tweak main fuel. what does 032 say your fuel trims are?

are you running a stock maf housing? what tune do you have?

How do I reset my fuel trims without disconnecting my battery?
Running stock MAF housing and on a custom tune.

[k0mpresd]

clear codes with vag to reset adaptation.

if you have a custom tune then this is a discussion you should be having with your tuner. not some random dudes on the other end of a computer. if you paid for a tune, the tune should work.

if you want to just dick around for the sake of doing something. then my first suggestion would be to try a vr6 housing and see what happens.

I need to try and get ahold of him. The thing is he assured me stock injectors would be fine on my tune, but he never even finished the tune past 5100 RPM.

If I could avoid having to deal with any bullshit and do it myself I'd be glad.

[k0mpresd]

stock injectors with an upgraded turbocharger? haha.

what ecu # do you have?

I have a CH, not sure of the numbers off the top of my head.
block 31 is fluxuating at .9(ish), all the way down to .727(ish).

Block 32 each trim stays at 0.0%. Even while driving.

[k0mpresd]

have you removed the n112 valve?

[Oricle]

have you removed the n112 valve?

I don't have any idea what that even is.

[k0mpresd]

solenoid valve that operates the combi valve. part of the secondary air system.

Oh. Do you have a diagram of it?
nm, just found a write up.

[k0mpresd]

i would have to dig for it. make sure that valve is plugged in ! it sounds like your adaptation is not working. 032 should always read something. even if it is only a decimal of a percentage. especially as rich as your car is running the ecu should be freaking out trying to correct itself.

I'll check it out.
Leaned out my primary fuel tweak and it's idling at about 14.7:1, than has a sudden down spike and goes to 10.69:1, than fluxuates back up.

[k0mpresd]

let the car just sit there and idle. the longer, the better. then check 032. if it still shows 0.0% then you most def have an adaptation issue. how much did you tweak main fuel?

The n1112 valve is also refered to as the SAI valve, correct?

I'll have to check. Don't have service out by my car.
So you're saying I should just leave my car running for 15-20 minutes and see how it goes?

[k0mpresd]

depends on the diagram. but yes, that is probably it. it is under the intake manifold. located right next to the n249 valve that controls diverter valve operation.

and yes, just let the car sit and idle. watch your a/f.

[Oricle]

Thanks for yo help. I'll try to see if I can find that valve.

[mike-2ptzero]

You might be better off going with a 3 bar fpr with that setup since its just a huge jump from 280cc on a 5 bar to 550cc on a 4 bar.

Problem is that your going from injectors rated at 365cc to a set rated at 635cc. The 3 bar will bring it back down to 550cc, you could even run a adjustable fpr to bring them down to 500cc with a 2.5 bar rating.


I just dont think the lemmiwinks adjustements can cut that much injector pluse to get you were you want with that 4 bar.

pm me if you have any specific questions. i really dont read a lot of the threads on here anymore. theres no point.

[Oricle]

Ok. Found the N249 and the N1112. Each had a couple hoses that seemed in decent condition going to them, and they were plugged into.

I'll have to check that out. Shouldn't lemmiwinks still be able to pull some fuel back? Thinking about the Revo file, just not sure if it's worth it considering I may be getting rid of my car soon.

[k0mpresd]

what does 032 say? theres also a relay that can kill adaptation but im not sure of the #.

how much did you turn down main fuel?

032 is still at 0%
Turned down primary fuel in chunks of 5%. Around 20% right now, and when it's idling correctly it's right where I want it to be(14.7:1). Than it has a massive rich spike that puts it to 10.69:1.

[k0mpresd]

you need to step up to a bigger maf housing. during driving 032 still reads 0%?

your tuner didnt "fix" readiness or write out rear o2 or something like that did they?

[Oricle]

Let me take it on a spin to the store and back. But yes a quick drive showed 0%.

[Oricle]

-23.4% part throttle
1.4% idle

[k0mpresd]

ok, good. and you still have lemmi @ -20% main fuel?

you need a bigger maf housing. and put a 3 bar back in. :)

I need to pick up a 3 bar. Stupid 01's came with 4 bars.
I'll look into a MAF housing. Any specific reason why? Revo and a couple other seem to use stock MAF housing, etc.

[k0mpresd]

all b5's came with 4bars.

bigger maf will lower maf g's. lower g's = less fuel injected. fuel trims will be easier to work with.

[gotaudi]

yep K0mpresed is right, Lemmi can only change so much, the max fuel that can be added/removed is 25% once you get beyond that you must change the hardware. ie the MAF housing. I believe most tuners do this they try to go up roughly the same percentage in MAF housing size and injector size, this eliminates the need to mess with the fuel tables too much. I would slap a VR6 MAF housing with the stock sensor and adjust your fuel trims as needed.

[maxspeed]

:: sits back and watches ::

noobs and lemmiwinks, this should end well.

Thank you. VR6 housing my best bet?

If his tuner tuned for the stock maf then he needs to use the stock maf. Going bigger is going to throw off his load and timing maps. Man this is not 2004, why mess around with bandaids when its just easier to get a real tune.

This is what I was curious about. Reason I went with the 550cc injectors is because I wanted to be able to run the Revo tune if they wouldn't work with my current tune.

man, can you read? look @ his fuel trims.

and he already said he doesnt want to deal with his tuner. so unless hes coughing up $5k+ for me7 software and trying to figure out what the fuck it is hes looking @, going w/ a bigger housing and making a few lemmi tweaks is his best bet.

what advice did you offer? slap a 3 bar in? that will fix everything.

the revo flash is a real tune though. well, for lack of a better term

your -20% in lemmiwinks and still a -23% block 032 is not a real tune.

pick what you would like to work with. and start tweaking that set up. whether it be the revo or your current tune.

Yes I did see his fuel trim, changing the maf is just going to cause other problems. At this point he is not going to over come the 75% increase in fuel that he got when he changed to the 550's by using lemmiwinks. Even if he did try going with a larger maf housing it also would have to be 75% larger and thats going to be way to big seeing that mean a maf that is almost 4.5" ID if the stock one is 2.5".


He really needs to cut it down closer to a 25% jump in injector size if he wants to use lemmiwinks to remove fuel.

Did some math.
With a 3 bar and reducing my primary fuel on lemmiwinks I should be able to run pretty solid and keep my part throttle fuel trims pretty close to -10%.

If this doesn't turn out well(which I really don't think it will), I'll go with the Revo file.
