What Have You Done To Your Stagea Lately?

[WAGON_BOY]

first time it was coming up left bank rich, then after a dyno run weeks later to check it........ it now comes up with left bank lean.

hasnt done so for a few weeks though.

also how can it know its the left bank when it's only got the one O2 sensor observing both banks at once.......... haha

[bigkevracer]

Stupid farking ECU. Must be a way to trick it.

Also noticed boost seems to be spiking which wasn't seen on the dyno sheets first time around. Scotty's wastegate mod will be here soon, hopefully that settles the boost down.

[scotty nm35]

I sent it today Ryan, you should see it before the end of the week.

Your controller won't be having an easy time trying to control boost, the actuator will definitely help it.

[bigkevracer]

Thanks Scott. How quickly do you need mine back?

[scotty nm35]

When you can, the next person in line will be hassling you, not me. lol.

Bushes were ordered yesterday for the 31 and Stagea, should be fitting them tmrw

$640 retail - down to $310

So glad i didn't buy them myself

Had the tune sorted out this morning. Idles much nicer now, and throttle is sorted.

Fault code was throttle circuit, had some weird behaviours (like fault light going on and off with throttle press/release with the stock ECU plugged in), but after clearing everything, resetting, and verifying, it now feels really good.

Now to enjoy it!

Also just paid rego! Woooo

This should be fun, tassie just updated to stickerless rego but qld hasn't

Yellow stagea

+ qld

+ tassie plates

- rego sticker

= .... we'll find out i guess

Was that because the throttle map was not set up correctly initially Ryan?

[bigkevracer]

Nope. I can't find a blank table referring to throttle mapping, and according to the tuner a blank F-con table should leave the ECU to control that function.

They have no idea what caused the fault, but I'll just have to keep an eye on it and if it reoccurs its either a problem with the throttle position sensor or a problem with the wiring harness for the cruise control.

Shitloads better though. SHITLOADS!

Nismo was awesome straight away!

P.S. There might be another Nismo coming up for sale very soon!

Gave my Stag a bath and fixed the amp for the spare tyre sub.

Time for fully flexing subwoofer very shiny white Stagea action!

[bigkevracer]

Drove home today, fault code free until not far from home... when the left bank lean and some kind of left bank voltage error codes popped up.

Throttle is still fine though, I'll have to see if I can find some kind of solution. Fingers crossed!

Car is now sitting out the back... tomorrow night I should start on the cooling overhaul. Unless the Scotty Actuator turns up tomorrow, in which case I'll be chucking that in

[PN-Mad]

Do you have any way of seeing the O2 correction that the stock ECU is reading? If so, is it cycling- counting up and counting down? That'll be whats causing the error codes, I'm sure its to do with the way everything interacts and not your actual AFRs changing.

i don't, no. Is this something the Cypher cable can do?

I'm sure there would be a way to loop the signal back.

AFRs look fine on the wideband so I'm sure they're not actually changing.

[PN-Mad]

Yes, the cipher cable will show you the info, but without the reflash ability, you can't get rid of the code. In my car its as simple as selecting the fault code and turning it off, then reflashing.

Its about the end of my ability- I don't know how the FCon is manipulating the ECU data. Best to get them to have a play with the O2 functions within FCon, and see if its able to take the role of O2 correction on.

[scotty nm35]

Oh boy, where to start.

The stock ecu is trying to adjust the fuel rich and lean many times a minute. If it doesn't see a corresponding change on the narrowband it will throw a fault. How can it do this with no control over the fuel anymore? There is no way to send a matched but delayed signal back to the ecu, you could throw it some random sine wave but our ecu is way to smart for that.

The wideband will show a set AFR at idle with the HKS, the stock ecu would normally be cycling a rich/lean pulse not holding a stable afr. Using the narrow band output from the wideband controller won't change anything.

[PN-Mad]

Can the HKS take over O2 correction, using the factory fuel target table (because FCon won't let you enter a target table), with either a wideband or narrowband feedback?

[PN-Mad]

Should work (theoretically) with factory injectors- any bigger injectors, the section in the target table for AFR correction would be to big and you couldn't tune correctly.

[scotty nm35]

Why would you want factory style correction anyway?

Target AFR's perhaps, but you would have to rely on the wideband a little too much for my liking. Without a full standalone we are frigging around in the dark.
