right perchased my stagea 2 weeks ago converted to manual last week upon taking it out on a test drive ran like crap idle wasbad from when i got it sometimes hunts or dies when coming to a stop i realize that that could be aac but i thought i had better check whats going on so installed wide band calibrated it at idle its at 17 then go for a gentle short drive stays about 17 not going into boost because of this.... plus no power really at all...

when driving back when it was auto noticed a strange flatspot where you would let of a tad then go back on it would jerk

checked for dry solder in the maf (pink e60) nothing completely fine no boost leaks before the turbo has a hybrid turbo good for around 550bhp 550 side feed injectors 1.6mm hks head gasket mines ecu. also fitted nkg spark plugs at standard gap i know this can be a problem on some turbo applications but surely not going to cause lean conditions ?

im a novice with Nissans any help would be fantastic thanks

You can't check for dry solder joints without a microscope, did you simply resolder the pins?

Sounds like you may need a tune, the Mines could be setup for any mods...

not soldered yet but will do. also yes i know thinking of going fully aftermarket but if i do will i run into complications with attesa system ?

No, why would you? There are literally hundreds of tuned Stagea's getting about, why would you think they are all in RWD?

I think you should do some in depth reading, search for similar issues, speak to a few tuners locally and come to your own conclusions as to what will work best. Now you have gone manual perhaps a Standalone ecu is your best bet, but you have so many options with the RB25

oh i see well i have done quite a lot of research but they all could be the problem so i will go at one at a time my main question was what are the main components that fail as a hole as apposed to someones idle being iffy mine seams to have quite a few issues ?

Because your ECU has someone else's tune on it no doubt. The more you mod it, the worse it will get.

hmm the ecu was installed by a tuner over here in England along with a load of other stuff (supporting mods) im trying to track down the original uk owner for more info but he spent a hell of a lot on this paperwork says that it had nistune installed but had a look yesterday and mines ecu with the gold plate

also whats the best ecu that can fit in the stagea without cutting looms ect plug and play i know a lot wont fit only mines and nistune

Most ecu will need a little bit of rewiring but best one to get in the UK for a manual Stagea is a link G4. You can also get rid of the maf while your at it. Have a G4 myself and can't fault it.

I'm sure once you have an ecu with a proper tune you will have no more problems!

The attesa connects to the ECU via 3 wires:

ATTESA pin -> ECU pin - Description

Pin 3 -> Pin 5 - Tachometer signal

Pin 23 -> Pin 37 - TPS

Pin 34 -> Pin 43 - Sensor ground

Thankfully the unit can be used quite independently. If you feed it a pull-to-ground tach signal, it should function without throwing an error code and turning off the 4WD.

If you are delving into different ECUs, the voltage drop associated with sensors like the TPS will influence what the 4WD thinks your actual throttle amount is. If you have some skill in electronics, you should be able create your own circuit to bend the TPS as you wish.

If not, you should probably learn.....the S1 can be a headache to tune.

thanks fellas yes the s1 seams to be nightmare at the moment aftermarket should solve my problems no end as for tps related things i have done a search but no luck on the voltage adjustment of the actual tps i have seen people mention this ?

      My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.

      Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).

      Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers

      Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.

      Pull codes via the self-diagnosis procedure. As far as I can tell this is just a sign of transmission issues but not a code unto itself.
