Dyno Results, come see.
 

ok, got it dynoed today, and basically it did nothing! I'm pissed and very discouraged! :-\ I have a d16z6, t25, dsm 450 injectors, S-AFC, (not afc hack, but hooked up just like the manual says) and 8 psi. ANY ways, First run on the dyno I ran 158.8 whp and 155.6 torque and then he retarded my timing and I ran a 161.8 whp and 150.9 torque, not that bad of numbers, BUT BUT BUT, i'm running a 9:1 fuel ratio!! I'm gonna screw up engine with TOO much fuel, I should be closer to 12:1! I'm very discouraged and sick of spending $ on this stupid car! So, the guy at the dyno (pyan technology Troy, MI) said I should either sell the afc, and buy a Hondata...or get a FMU, put the stock injectors back in and keep the afc. What should I DO? I ahve NOOOOOO idea, i'm too discouraged to think straight!
also, my settings on the S-AFC are Hi -40% all the way across and Lo -50% @1000 & 2000Rpms, -44% at 3000 and 40 all the way across from there.

Re:Dyno Results, come see.
 

get your p28 chipped and run uberdata...just as good as hondata but without the bluebox.

Re:Dyno Results, come see.
 

if you're not running the hack, then what are you running for management ???

Re:Dyno Results, come see.
 

obviouly nothing. I don't know enough about it, I thought i did...but guess not. What do you suggest, hack or FMU . And do you think the 450's are too big for my turbo? heres a decent FMU http://cgi.ebay.com/ws/eBayISAPI.dll...904124742&rd=1
also do I need a missing link check valve?

Re:Dyno Results, come see.
 

I would check more into getting the afc to work right. It should not be doing that. Or chip the ECU, better than hondata and cheaper.

Re:Dyno Results, come see.
 

I know nothing about chipping the ecu, not even a clue

Re:Dyno Results, come see.
 

You are running the AFC hack...noob.
The hack is just the afc installed as the manual says, but you put the values to negative and run bigger injectors

Re:Dyno Results, come see.
 

reguardless, I'm running too rich. Even at idle it's set at -50%...the most it will correct for, and it's still runnig at like 1:1 or 10.5:1, that's still to rich! I got this out of the FAQ No fuel pressure regulator is needed. No upgraded fuel pump should be required. This setup is normally god for ~10psi

Re:Dyno Results, come see.
 

that turbo is tiny as ---- and your only runing 8psi, what more do u want. 160 to the wheels isnt too bad. a stock z6 will only put about 105 to 110 to the wheels. your got abouta 50hp increase with 8psi which sounds about right. YOUR NEED MORE BOOST! especially if your runing rich. turn it up and even out your a/f ;)

Re:Dyno Results, come see.
 

I think he is happy with the numbers, his problem is the fuel really. 161hp and 150 tg are decent numbers

Re:Dyno Results, come see.
 

Yes, I'm happy with the numbers, but i'm concerned about washing down my rings and cylinders with too much fuel!! which will Ruin my engine! duh! If I up the boost to 10 psi, it's not going to do anything to my a/f ratio, my car will adjust for the extra boost and run just as much fuel to it, making it too rich still. I need answers people, how do I get my fuel down to 12:1?

Re:Dyno Results, come see.
 

oh well then turn up the boost anyways.lol ;D

Re:Dyno Results, come see.
 

turn it up to 15psi and I gurantee you won't run rich anymore. 8)

Re:Dyno Results, come see.
 

look in the classifieds, i believe streetkings is chipping ecu's for free, you'll just have to pay for supplies which would be like 15 bucks at the most and you can buy your own chip burner for about 70-100 bucks and get the uberdata software for free and be able to tune your own car just like hondata, you can even just run a basemap (what i'm doing) until you get the hang of tuning the uberdata, did the guy even mess with your afc settings or just your dist.?? something doesn't sound right, idle doesn't really matter and should be about the same as every one elses settings that are running 450's, you're settings aren't really going to be different until the car goes in to boost, then you just adjust a few rpm point accordingly per dyno pass, then concentrate on another set of rpms until you nail it, somethings not right and you should have been able to get a better a/f than that, it's basically just trial and error until you get it within a safe margarine. good luck whatever you decide to do.

Re:Dyno Results, come see.
 

Why dont you lean out the VAFC more at hi throttle???

You're set at 40% on hi. Why didn't you try tuning it? Your low throttle is part throttle (whatever you have it set for). Hi is WOT and is what you should be leaning out :-\ :-\

That or up the damn boost. ;D

Re:Dyno Results, come see.
 

What were your AFC values on that run? Hi and Low.

Re:Dyno Results, come see.
 

The guy at the dyno didn't even want to touch my car at first because he said it wasn't done right in his opinion ::), but he's not the low budget type of person, he owns a freakin' NSX!!! (prick) So If I change to uperdata, Do I sell my afc, or keep it? Also, my friend wants to go in and split the cost of a protable Wideband so we could tune are cars as much as we want, rather than paying $165 per hr at the dyno everry time! What do you think of that? And what are AFC valves? my hi's and LO's are in my first post, reread it.

......Ok I read up on Uperdata, and I"m still clueless, it sounds VEEERRRRY complicated!

Re:Dyno Results, come see.
 

I think he's just looking to boost without getting too complicated with all the chipping etc... He's got what appears to be the right setup, he's just trying to work with what he's got and move into chipping sometime down the road...?

So the question is, why does he have too much fuel? Wrong injectors? Wrong AFC settings? Bad O2 sensor? IC and/or piping leak? Bad resistor wiring?

Chipping the ECU appears to be the "typical answer" for every ------- problem anymore...

Re:Dyno Results, come see.
 

Because it works way better than the afc. All my friends are chipped and there cars run in the 13-14 second range. And the friends that do have afc's always have problems with it. Always running to rich. I think that the afc is for N/A cars not turbo cars. I don't like em.

Re:Dyno Results, come see.
 

find a shop that can dyno tune your afc, that seems like the simplest solution, obviously the guy doesnt know what hes doing if he cant tune a simple vafc.

Re:Dyno Results, come see.
 

i took it to a professional import dyno, and he did know what he was doing...but I have it leaned out as much as the afc will let me, and it's still too rich.

Re:Dyno Results, come see.
 

to tell u about my set up i run a safc with stock injectors a fuel pressure regulator and fuel rail on my d16. at first it was to rich i leaned it out and also took gas away from the fuel pressure regulator and now its running much better..ima take it to the dyno hopefully soon and video tape it for u guys..i think u guys heard of TITAN MOTOSPORTS there the closest dyno from me

Re:Dyno Results, come see.
 

set your lo settings to -46 accross and that should get you back to a stock 240cc equivalent...might want to even use -47 at 1k...this will allow your ecu to make corrections for afr which is what it'll try to do anyway in closed loop.

set your hi settings to -40 and make a wideband run and note the afr throughout the rev range. slowly lean it out going to a higher -#. when i was running the hack at 12psi i had my hi corrections all at -50.

it works like this because you are correcting the voltage that the map sensor is sending to the ecu and it shifts you accross your fuel maps in the ecu as well as your timing.

try that and that'll get you back on track. i would suggest using a btm w/ the hack.

i would suggest considering running uberdata...if he suggested hondata he should be able to figure out uberdata and you'll be good too.

Re:Dyno Results, come see.
 

from what I've been reading Uberdata is totally amazing, and the tuned results are sweet. I"m thinking about changing it to that and selling my afc so that it will be more tunealbe. My friend and I are possibly going to go in together and buy a portable wideband so we can tune are cars, so we don't have to pay $165 per hr at the dyno. The only problem is I NEED a car. I have to bum rides off my fiance and parents, and my parents are leaving town for a month next week, so that means I only have my fiance to bum off, and if she's working, that means out comes my mt. bike...yeah, lame I know! ::) so how hard is it to install uberdata and get it on the road? I'm planning on sending out my ecu to street_kings after I decide if this is the route I wanna take.

Re:Dyno Results, come see.
 

buy a spare p28 ecu send it to street_kings for chipping (see classifieds for details). and he'll even send u a base map I hear. swap ecu's and you should be able to drive your car! no down time.

Re:Dyno Results, come see.
 

I have the same fuel management as you do, only I gotta b16a. I was at 8psi doing 175hp before I got it tuned. Now I'm at 10psi at 234 hp. I was runnin super duper rich. Your solution is to turn up the boost to 10-11 psi. put just 1 check valve between your fpr and intake manifold incase your map sensor sees to much boost. But definately turn up the boost. By the way that tuner you went to is wack if he couldn't get you to turn up the boost. I can post my vafc settings if you want remember I have a b16 i don't know if it makes a difference.

Re:Dyno Results, come see.
 

if i get my ecu re-chipped, Don't I have to get a wideband to tune it?

Re:Dyno Results, come see.
 

You won't have to get a wideband. If I were in your shoes, I'd find someone on the site that is running uberdata with your similar setup. (someone has to be running it) Get their uberdata maps. The more tuning they've done, the better. But any "ok" basemap should get you up and running. Find that person, and do whatever it takes to make them want to help you. Money is usually a good "tradable".
I know, I hate those kind of "---- this, what do I do" situations.

Re:Dyno Results, come see.
 

Wow that sounds right on the money with my friends B16. He was running super rich and got 180 whp and when he got tuned he pulled out 230 whp. He has hondata though. same thing. same boost also.

Re:Dyno Results, come see.
 

lol, that sounds like it came straight outa Jeff's mouth.

I would go this route as well. Plus retard at the dizzy.

Re:Dyno Results, come see.
 

I can turn my boost up which will help when i'm in boost, but when i'm just cruising around in vacum is when i'm pig rich too, that's what i'm worried about, not boost!
.... i'm still a noob, but retarding it at the dizzy is the ignition right? IT is retarded like 9 degrees at the distributor, guy at the dyno did it. Uberdata is WAY better than the set up i have isn't it?

Re:Dyno Results, come see.
 

why don't you lower your fuel pressure, if you are rich all over. It will lower your air/fuel acordinglly. 98ctr

Re:Dyno Results, come see.
 

you can turn down the fuel pressure with a fuel pressure regulator (get one), or turn the boost up to get a better Air/Fuel ratio.

Re:Dyno Results, come see.
 

Basically did nothing??? What're you, high? You show me a stock d16z6 that puts out 160whp and tq. What the hell were you expecting with the hack and a small ass turbo?

Re:Dyno Results, come see.
 

you need to adjust your narrow throttle just lean out your lower rpm range 1k-3k rpm. my narrow throttle settings
1krpm -42
2k -41
3k -40
4k -38
5k -37
6k -36
7k -36
8k -36 this is with the apexi vafc & dsm 450s, 255 walboro in tank pump.

Re:Dyno Results, come see.
 

do you guys not read the fisrt post, I'm happy with the hp numbers, that's NOT thte FREAKIN' problem! Also, if I spend the money to get a fuel regulator and a fuel press guage, I might as well, sell the afc, and go to uberdata and have my own standalone for cheap, and safer. (which I'm palnning on doing. I'm actually thinking that afc might not be working, We adjusted it -10% from -40-50 at idle and it BARElly did anything for the afr.

Re:Dyno Results, come see.
 

go to the apexi website and look at their update on wiring diagram for the vafc. they have a clearer diagram now. the one that comes with the instructions suck. also you need to connect the vtm wire, in the vafc instructions it doesn't say to connect it. see the updated apexi instructions on their site.

Re:Dyno Results, come see.
 

I have the S-AFC and I JUST got back from RE-checking my connections for like the 15th time, everything looks great, connections are good and on the right wires, maybe there is something internally wrong with the s-afc, it's almost like it's not kicking in and telling my car to give less gas so that my injectors don't flood my engine. In theory, I am actually giving less gas tahn stock and I'm still running rich at -50% at idle.

Re:Dyno Results, come see.
 

were ur injectors running right before u bought them?

maybe u can even get some 390s

Re:Dyno Results, come see.
 

As far as I know, the injectors were running fine when I got them. My friend gave them to me that he lad laying around. He bought a JDM engine for his Talon and so he had some extra ones ;) I'm going to recheck all my resistor wiring, It almost seems that my car is running in Open loop all the time and not going over to closed loop when i'm just 1/2 throttle cruising. what do you guys think?
