Dyno Run

[Rolls]

Im assuming the apexi neo is an SAFC, if so hes tuned it too rich you want to aim for ~12:1

Notice how the line is very wonky, it could be tidied up a lot.

so what should i tell the tuner again?

my mate suggest to take it to him tomorrow?

what should i suggest to this guy for the afrs 12:1

f**k i feel so jipped

[R31Nismoid]

I'd go back and say your not happy with the tune.

And maybe ask for half the money back as your not happy, but you'll cover his time only.

But i wouldnt let him re-tune it given he got it that wrong the first time

[Rolls]

Where do you live, I'm sure there are some reputable tuners around.

[ztuned]

i;ve got the following mods

3inch Cat Back Exhaust,

Front Mounted Intercooler

Apexi pod filter

BOSCH 040 fuel pump

3 inch dump pipe

SAFC

and manage 212kwrw @ 11psi

not much difference in mods, but big difference in power

[R31Nismoid]

Ye, a happy dyno is also a happy thing to have too.

Realistically he should have around 180rwkw

[Zas)-(]

i live in kogarah..... theres not many REPUTABLE tuners.

keyword = reputable

could there be a chance his dyno scores are just low

???

wtf 212... man dats a big diff

ohh.... i aint goin back to him....

ohh well cash gone gotta live with the fact i blew it on a shit tuner....

guess i'll save up for a turbo and then go for a better tuner in the area..cheers guys

I'm with nismoid when he comments about the FPR.

"Upgrading" it is a complet load of shit.

I'm running 300rwkw with the factory FPR, and its still got more to go.

Ditch the tuner, and get some money back.

[RRob]

My old 25 managed 216rwkw. S2 with fmic, full exhaust and 13psi

[Zas)-(]

.... no need to get money back,.... i got sumthing better

most tuners leave off word of mouth, wait till i tell most of the bois whats happened in the area haha

i'll leave it and go for a more promising tuner later on. whatta task to find a good tuner these days

[Zas)-(]

Called and talked to the tuner

the tuners words are :

Your fuel pump is dumping in too much fuel as the stock engine cannot handle it. I have already put it down to almost -22 anymore is bad.

He said i need the adjustable fuel pressure regulator or else he cant tune it because the pump is dumping in WAAAAY to much fuel and flooding it.

thats why its running rich and thats why its stock afrs etc

if i had a bigger turbo then easier to handle but atm i cant... he'll charge me another 180.00 dollars for the retune afta i get a regulator.. <--

wat do u guys think

[WogsRus]

crock of shite, the unless your running oversized injectors and you don't know about it, then the reg should be fine, a stock reg works at 38.5 psi static.

[The Mafia]

that is the biggest crokc of shit ever.

The standard regulator is FINE! I run 300rwkw with mine! As long at your rail has a constant 42psi then there is nothing wrng with it.

And -22? I have taken well over 50 - 70 off some of my load points!

this guy is a f**king dipshit. I don't work for a shop, and it seems like I can tune better...

LOL

i used " the mafias " car as an example and he said that it was more likely that ppl on skylines australia is bs.... and that most ppl here are biased ...

does anybody have an idea as to WHY? he would of said this to get a regulator and not tune it better?.

my guts telling me he wans me to come back ,giving lil power gains each time so keep coming back so he gets more cash each time.?

btw.. he supposingly is a reputable tuner in the hot fours magazines and many ppl from the hot 4's have done there cars by him

this is how i chose him as a tuner..

* nah there ppretti much standard injectors? maybe the ecu was re-mapped without me knowing?? n he cant lean the fuel out??? ( guess )?

this really suprises me a tuner would say this, and its almost scary that he works on cars. A FPR is exactly that, it controls the pressure of fuel in the fuel rail. Its important to understand how it works. The fuel pump pumps the fuel it hits the fuel rail and regulator, the regulator controls how much fuel pressure is going through it. Even at stock levels the stock pump is pumping more fuel than the engine needs so the FPR regulates how much fuel is needed for the motor and the extra is returned to the fuel tank. So even when you get a higher capacity pump, that extra flow doesnt go and "flood the engine", it just gets returned to the tank. When you bump the boost up, you go through more fuel to counter the increase in air, so with a bigger pump you can meet these needs, but you still wont be using the full flow of what the pump produces so once again the regulator maintains the pressure of fuel required and any extra will be returned to the tank.

A higher flowing pump wont flood the engine as long as your FPR is working, hes talking bs.

[Tom Tucker]

Yeah man, the ecu controls how much fuel is administered by opening and closing the injectors accordingly, the fpr has nothing to do with it. Old mate doesn't know how to tune your ecu, simple as that

[The Mafia]

exactly. You could put a 700hp pump in your tank, but the factory FPR is always only going to let the injectors see 42psi - the factory fuel pressure. Then you adjust the powerfc to suit. If this tuner is saying that your pump is too big, then he should not be tuning cars at all. And as I said before, he's only taking -22 units out? I take HEAPS more out to get my afrs up to 12.5:1

And f**k me, he wants you to put a adjustable FPR on so that he can f**k it up some more? Holy shit, he doesn't even know how a factory one works, how the f**k is he going to get a Aftermarket one working?

ahahahah what a loser. I'm biased hey? Take a print out of my Dyno run to him - tell him to shove it up his ass.

[SXR]

I reckon your AFM needs cleaning.......thats probably all to it

[Zas)-(]

... afm needs cleaning.... i'l clean it anyway just for the general purpose of doing it

lol.... well at least i know that i am on the right and that he did a shit job..

i think this guy doesnt know how to tune the stock regulator...

atm my car sometimes idles funni too

i realli need to get her tuned again

... maybe you guys should call him up and talk to him ahahahaha ... thanks guys for telling me how it works.

although i lost 500 bucks its a lesson learnt in knowing there are shit tuners.. <--

not all just one .. I.S MOTOR SPORTS !

[Zas)-(]

w00ps again
