Strait to the point. THis is my turbo setup-
t3/to4E hybrid Drag turbo.
High pressure pump
7psi turbonetic delta wastegate
370cc RC injector with apexi VAFC
intercooler + piping done good
Ignition is stock, non change

My problem is when I boost 1-3psi car runs good, but when I step on it car goes BLLuzzzzerrrr ...Then check engine light come on.. Blink once I checked..(oxygen content)... What could be this problems on my boost guys?..I mean at even 3psi the car still runs crappy...Slow launch and very slow..

VAFC setup
1-4k -40
5k -38
5.5-7k -35
(I did try other setting and try lower then try higher it, but still the same)

Could anyone point me to some type of direction what I do wrong or need something,.... I'm clueless here...help will be appreciated...

 

did you make sure to set both the high and low throttle maps on the vafc?

 

yeah...In wide throttle right and Narrow throttle..Both setted, LVT + HVT for both...
And was VAFC setting is just base on HVT LVT setting...WIDE + NARRow setting right?...Nothing else major right??? I leave Vetec same as it is 5800, 5400...throttle is low 70 high 71

 

you need bigger injectors.

 

I just order 370cc ...You mean I cant run this ?.. I think at least this can run up to 7psi or so...Could it?? Or bigger injector help solve this problem???440cc??

Any think off a wastegate problem?...well I order from Drag it comes with 7psi on it..I didnt change it or anyting..could it be that problem?..Anyone know how to adjust it????

 

ya the hack is meant to run on 440 injectors... up to larger injectors .

or try trimming less fuel.

 

So the 370cc injector is a waist? I cant run those injectors with the Hack?... You think I should spend more money on 440cc?? or just lower fuel on 370cc is ok....

Thanks for the help guys...

 

You're leaning out on the AFC for 450cc injectors with 370cc injectors. You're getting an O2 code. I know you have no AF meter as you'd know from it that you're going super lean under boost.

Try adding a bit more fuel, and don't boost too high as your injectors/required fuel cut aren't enough to boost very high. When you hit CEL 3, that is your limit.

edit: BTW, I was born in Oswego. :>

 

are u sure its cel 1, could be the iat code cel10, is it one long flash or one short flash??? trust me w/ a high press pump u dont need 440's, i have rc 310's and a nos inline pump, and my vafc settings are a lil leaner than urs. 1-2 -44 2-4-39 5-6-33 6-8 -30, and my a/f is 11.0-12.5 across the board. ur not technically running the hack w/ a high flow fuel pump right?? after u fix that prob,i think ur specific setup would benefit from a fmu though, not 440's

 

Check your missing link or what you are using to by pass the map sensor .

 

are your injectors peak and hold or saturated? if they are peak and hold you need a resistor box. if this is the case and you aren't running a box this could be your problem. have you gone back to check the cel to see if it's 10 or 1?

 

I'm currently using a Airtex high press fuel pump, with 370cc saturated injector. No resistor box though, dont think I needed cause it saturated..

And for the check engine, i use the paper clip and test out those two wire next to the ECU for code and it just blink once.. (fast) I mean even if I didn't use paper clip it still blink once when start up engine... I think that It means 1 or 6th gen accord different from other car on code stuff??...
I didn't use any check valve or miss link cause using the Hack, I dont think we need them? do we??

Any more help appreciated guysss

 

Anyone can think of a ok setting for me to set on my VAFC hack so I can figure out an ok path to go with fuel..??

here my setup again
t3/to4B
high press pump
turbonetic wastegate
intercooler
370cc saturated
VAFC hack
- and basicly that it, all the other is pipe and BOV ...
- One more question, I have an FMU and check valve hanging around here doing nothing; could I put them on for the sake of it and see what going on or it just mess things up and more confuse that way?

 

Your OK setting depends on your OK air-fuel ratio. Only you can determine that.

And I still think you are going lean, but you can't even tell us your AF ratio. Get some information to go on, pls.

 

your engine's f23a?

i also have f23a, i use 450cc (dsm), resistor box, no inline fuelpump, no check valve, with vafc.

mine also throws a code, but the car does drive like a champ...lil rich/lean here and there, but i can't get the HVT table to affect the a/f ratio...i'm kinda stumped...i'm seriously thinking about aem ems...hopefully with that, i can also eliminate the issue of self-adjustment ecu which happens with obd2 ecu's...

or only if hondata would tell me that i can use p28 and then reprogram it for my car....

 

Again, how you tell what ratio is in the A/F gauge.. It all color and stuff...is the dead top stoich is 12.0? or different ratio?

 

uhhh...answer my questions first!

hehe, well...to get the a/f ratio, you need something some sort of wideband meter...like fjo, techedge, aem ungo (or whatever it is)...

basically, another oxygen sensor which you plug into exhaust system...

 

don't mess with the fmu and check valve, you'll only have another problem to fix. with your corrections at low throttle you should be running way lean on 370cc inj. -35 correction will bring those 370cc to a 240cc. at high throttle (i think 50% throttle and higher) your corrections will need to be different because your ecu goes to a default fuel table and dumps more fuel based on rpm and tps if i'm not mistaken. you'll probably need to go lower than -35 and this is going to limit the amount you can boost because the lower the correction number the less effectively you are removing map sensor voltage.

reset your corrections and then your ecu and see if it continues again at lower boost levels. ultimately i'd suggest using 440cc-450cc injectors. good luck.

Exactly. Get some 440's or higher. 440's you wont need to use a resistor pack since they are saturated. Sounds like you are definitely leaning out.

 

Theres serveral people I have seen use 370s, all your fuel levels will be somwhere closer to the -25-30 range. The hack is only good for about 7psi with these injecors before you trip a map sensor code because you are not taking as much fuel out.

The self-adjustment that you've been told is bad is called closed loop, and every last ECU ever made does it. I hate when this subject crops up, you've been misinformed.

 

kool, please clarify!
tia.

 

Hmm...So technically if you increase the fuel I mean from -35 to -25 that mean you are adding fuel right? the higher the value the leaner your car get, am I on the right track?...

So right now i'm at -35 and up on all of my RPM range i'm running very lean... So if I increse the ratio and put all down to like -25 to -30 car run smoother am I correct..?..

I think I got the track now...But one more question, about the wastegate; does it come automatic setting or you have to set the wastegate by your self?..I bought it from Drag, it a turbonetic 7psi thing, If it can be adjust do I have to tighting it or loosing it for better boost setting????

Ohh and I got the boost control though..

You have remeber these are negative numbers!!!! -25 will always be a larger number than -35 which means Yes you are adding more fuel which means the richer it will run.
