I'm running 550's in a 94 STI JDM in Japan. The car has the Power FC installed and I'm looking for reccomendations for the injector lag time. I'd also like to take a look at some maps if you guys post them. I was looking for a website with mods and maps posted for experimentation purposes. I'm an american and I don't speak japanese so I'm not getting too much help here. I'm also in northern Japan where there aren't many tuners. Any help would be appreciated.

Jflow23

wow...nothing

I know somebody is running 550's and has their power fc set correctly...can I get a little help?

Pavlo

the default timings are very close to that of the 550s, which I have but not to hand.

are you using the hand controller or software to do the mapping?

Any specific questions for the mapping?

Also, you may get a better response on bbs.22b.com also there are a number of self tuners that have discussed various mapping issues on there, which should be easy to find with a search.

Cheers

interested if you have an more listings Paul. like phase 1 440's ?

lag time depends from manufactureurs.
for example,denso 540cc,12 holes ,side feed and high impedance have 0.79ms lag time

Pavlo

At what voltage?

Jflow23

thanks for your help...

Andy.F

The lag time also changes with fuel pressure !

yep, and finding all these parameters is like panning for gold

beryllium

lag time and injectors capacity are at 14 volts and 3 bars but the PDC don't ask this.
the PFC is maped for JDM STI .for example EJ207 PFC version (sti 5 and 6) is maped for 505 cc and 0.76 ms (read in the notice manuel).
if you have this configuration,you have to introduce 100 % for injector cycle and 0 ms for lag time.if your injectors are 660cc and 0.79 ms,you should map 550/660 = 83%
and 0.79 - 0.76 = +0.03 ms

Sti5/6 with 505 (or 550) injectors isn't right. 440s more like.... what is this notice manuel and are you sure it said sti5/6 are over500cc injectors??????

Tony.

beryllium

440cc are for european STI,butJDM STI have 505cc.
read in the japaneese power fc notice manual.i don't read japaneese, but hopefull they have same digits than us

There was no european version of the STi 5/6 tho??????? Only new age cars.

tony
have a look page 49 of the manual instruction supplied with every new PFC.no doubt possible
if you don't have let me know your e mail and i send out to you

Hi,

If you could send the manual that would be great.... toe_scooby@hotmail.com . My PFC came from Japan with no manual

Cheers,

Thanks for the manual Charly.

You're spot on, page 49 says the EJ207 (98/9 - 00/7) has 505cc/min injectors with a lag time of 0.76ms. At what seems to be 14V and 3.05bar pressure.

What pressure are the injectors quoted at when we say 380cc/440cc??

Tony.

beryllium

hi Tony
no enquiry about 380/440,may be in the EJ20 version of the manual?,but no reason to be different.
all modern cars alternators are delivering 14 volts and genuine FRP are rated at 3 bars under atmospheric pressure

Tone Loc

Yeah, that's what i thought...3 bar. I did have a set of sti5 injectors but sold them before i could get them flow tested. Would have been interesting to see the results as i've never seen the yellow injectors quoted at 505cc. Maybe i'm missing something obvious .

Tony.

Andy.F

Like there is a mistake in the manual ?
I have never noticed a difference in maximum flow capacity during mapping them, injectors seem to top out around the same level as the turbos on V5 and 6 Sti

RonaldK

can one of you guys send the manual to me : hpoppoe@hotmail.com

thanks a billion

LOL.... a mistake, never .

Can anyone send me a copy of to subyfiles@yahoo.com

Thanks

SoNiCa

anyone?_-

PeteTheFinn

Could someone send me the manual too, please.

pete@subaruclubfinland.net

I will try to send the manual to all tonight... be warned tho unless you can read Japanese it's useless. You can make the numbers out for the injector scaling bit which is what we were discussing above.
