ok trying to wire in a hks fuel defender. now there is 5 wires. one for power and ground wich is easy the other 3 is the problem. which wires do splice into for the air sensor, rpm and air signal going away from the ecu?help some one?
hks fuel cut defender

Here's the 1jz pinout, it is a 1jz i'm assuming.
Haven't seen another person from SK around here ever, good to see.

tired splicing into the map sensor Wich is w2 I belive. then spliced into 17X for rpm signal and then W1 for the air pressure signal away from ecu(I don't understand but that what the hks insturctions say) Took it for a run and check engine light was on and it idel funny and still hit fuel cut.
Its a K3 hks fuel cut defender with 5 wires coming out of it.
As well the fuel cut defender is set on 9

I think I figured out whats wrong the W2 get cut in half the one running from the map sensor goes into the yellow wire then the one running from the pig tail off the ecu goes into the white wire.
Makes sense anyways when hks says use wire running from the ecu. I though you had to tape into 2 differnet wires but its only one.

I would not use it.. I have a buddy that had one on his 97TT 6speed and we took it off and put a Greddy BCC on... the HKS unit is not well liked by anyone I know... you can check here about it and it has pix of the install this will help you if you want to use it.. it is your car...

yeah you got it, that should work.
As for nobody having success with it, that's just not true. Lots of people on here and others have had success with it. You just have to understand what the device is doing so you don't tune to an unsafe level.

you'll have to bring it by tommrow or even later toighnt. Now that we know what to do should only take us 20 min tops to fix it.

Yeah, hopefully 20 minutes will do the trick.
I think your dad was getting kind of upset from my annoying muffler last night, haha
I don't like fuel cut defencer devices either :nono:
But there is a but :sarcasm:
How can you run some more boost.Say from 0.7 bar to 1.2 bar where
the JDM turbos and 440cc injectors reach their limit,it is the only chance
to get to a full BPU mod.
The only alternative way is a standalone ECU (+ $ 1400 without tuning)
Then if you have a standalone and you can run more boost,it will be fullish not to get a bigger turbo or better a turbo kit (+ $ 2000 minimum)
And last, the big turbo and the standalone are useless without an upgraded
fuel system (+ $ 1500 minimum)
And all that will be good if you have already an upgraded clutch/disc,big 18" wheels & good tires,and maybe a good torsen LSD so you can put the power down the road :sarcasm:
Damn...big HP and high speed tech cost a lot of money

tired it toighnt wired it in to the green black wire and no success. car just had check engine light on and idel shitty. mabye the hks unit is faulty??
I searched here and supraforums and I can't belive there isn't a thread anywhere about how to wire this in.

Not to jump on any sort of bandwagon (not my style) but honestly every thread I've seen says the thing is a total POS.. Now, yeah this is the internet, but unlike most topics 95% of the ppl agree with each other on the negative side of the unit.
That's probably why its a bit more difficult to find wiring diagrams.. I realize it's not helping you at all, but perhaps the insight cleared that up.
There are two Fuel cut devices in the market,at least more popular :sarcasm:
1) HKS FCD
2) Trust / Greddy BCC
Both devices are adjustable,so we can hit fuel cut at any level (boost) we
want.But the devices have their limit on boosting more than 1.4/1.5 !
Anyway...people say that the FCD is for JDM supras and the BCC is for
USDM & EUR spec supras,which is not true.Cause RHDJapan.com
gives the Trust/greddy BCC for their domestic cars/supras...
As which is a better device...the BCC is a more reliable device

if your have the 5 wire unit, it is the wrong one for your application.
the 5 wire is for KV applications, such as the 7m-gte.
the 1jz uses the 4 wire unit.

Do you think it would be ok to install an HKS FCD on a stock JZA70 car at setting 9 and try to get 15/16 psi without an AFC or wideband? I guess it is hard to say how much is too much without being able to see what is happening in there.

Your right. It says right on the back of the box the JZA70 uses the standard model. Fuck.
I bought this thing over year ago now and I don't know where the receipt is...

just keep it in mind that a lot of the replies you will get on any forum can be 100% bullshit posted by people who dont have an idea what they are talking about.
there is nothing wrong with the hks FCDs. you just need the correct model for your application.
