Old ECU to run yellow injectors

[sultan]

(orig title STI V2 ECU but subject changed now!)

I believe this is the 6K? What AFM and injectors does this use?

Are there any other 4 plug yellow inj ecu's?

[funkytown]

it still uses greys and green afm AFAIK.

nick - kamineko is the wizz on this stuff.

no four plug factory ecu that runs yellows that I can think of.. maybe one of the auto GTB (BG) ecu's did - i think some came in four plug as opposed the 1plug (of fail).

no v1/2 ecu ran yellows apart from those chipped which obviously arent factory.

[sultan]

that's what i think too... hoping some one contradicts us!

[BC5RA]

Funkytown is correct.

[kingersman]

all v1/2 ran greys

v2 sti ecu = 6k

v2 sti ra = 7k

all 4 plug as well

before i switched computers, my standard computer ran yellow injectors in a v2.

[kingersman]

it would run them but be really iffy wouldn't it?

[Guest boostcut]

na it ran better than it does on my chipped ecu. i still got relatively good fuel economy. (450kms) now i get 250 to a tank open road driving.

[kingersman]

i get about 350-400 town driving

this is a almost standard v2 wrx tho

[Guest boostcut]

mine is a v2 wrx too. dont know why it uses so much gas, i haven't really bothered to look into it.

wait...

or is this now after you've switched computers?

[Guest boostcut]

na it ran them fine on a factory ecu. everyone said it wouldnt, i even sold my old ecu to a guy that had yellows in his v1 and it ran perfectly.

since i have put the new chipped computer in it, its run well but a bit smokey on boost and uses alot more gas.

[sultan]

do you mean std v2 sti or wrx ecu? green afm?

[Guest boostcut]

yeah green afm. standard wrx.

[sultan]

i don't mean to sound like i don't believe you, but i'm wondering if any one else has done this before? just wondering if yours was an isolated perhaps "freak" ecu

i'm planning the parts to buy to dissestablish my current setup. if i could buy a green afm and std wrx ecu (or even the 6k) to use yellow injectors that will save me a whole heap of money but more importantly much less hassle!

[funkytown]

you can run yellows in a v1/2, even on the RS's i know ppl running yellows on their factory ECU's

what you will find though is that it just runs really rich.

[sultan]

probably a good thing for dumping lots of boost into it. at least it's not going to lean out. so i suppose the only down side is fuel economy and power efficiency from lack of correct timing.

do you know if any of these people have been onto a dyno?

[funkytown]

no dyno, boost, AFR's to show as "evidence".

Mike runs them in his RS track car tho.. so gets the jandal most of the time - and hasnt assploded yet. Not the evidence you really need though.

[deathz0r]

Hmm I run yellows on my standard v2 WRX ECU - no aftermarket chip or anything.

Like boostcut said - everyone said it would run rich as hell. IMO, it runs better and I get the same fuel economy

No harm 'til you try it mate

[funkytown]

to be fair... ^ is jewish..

dont listen to his jabbawokie.

;D

I'm in ya post Jon, muahahahahaha

This is not a recommended course of action. You _CAN_ use a hammer to disassemble a fragile instrument, but it really isn't wise.

There are NO four plug ECUs that ran yellows from the factory. Some can with chips. The worst that can happen is that you hydro-lock your engine due to flooding..... but sultan would already be familiar with that

What happened to your link anyway? Just throw the injectors in and scale the fuel map...

what turbo do you have and how much boost? do you ring it out often?

my problem is that i have to decide to go facto ecu+afm route, or keep my link (but pay for it to be retuned)

You can also try tow a car 30km across town to take it to a soldering iron. I'm over having lots of power now. Have a baby due in a month, don't need to open the car out to 240kmh to have fun with it any more.... Want a quick spooling setup again, so i'm selling off all my bits and replacing with factory stuff.

Close Funky....

Only i'm still running greys....

If someone was willing to supply a set of yellows i would give it a go though..

[zarnah]

I had yellows in my BF with that ecu I got off you mike and it ran fine, that had an "unknown spec" chip in it though haha

[Guest]

I dropped yellows in my BF with an ECU marked H3, it has a pink sticker (STI?) and they perfom beautifully!!!!!!!!!!!!!! I say go for it, you cant kill an engine from over/under fuelling it so why not try? You mave however need to re-tune your IAC and TPS to match the new gas input... if it blows smoke drop the gas you use back down to 91oct, I run 91 in my s/w and have blitzed a few homo's homies in rex's out my ways!!! always fun....
