I seem to remember somewhere way back I read (perhaps in the G35 manual) that if the ecu doesn't get the brake signal for a while it goes into throttle limp, not sure but keep it in mind if you do attempt it.

I worked out how to get rid the Emanage Ultimate ignition error code, it can be done inside the EMU box so if anyone wants the code gone, send it to me and I will upgrade it.

Mmmm..... Boobies!!!

My car pulled 5 more psi(so 15psi)by the time in hit 3,000rpm on stall..... Got there a lot quicker too on stall!

Launches hard!

Well done guys.

If you want to try it, its pin 55 on the ecu. Its a pink wire with a blue line.(around the middle of the plug.) Just make sure you tape up both snipped ends well. :thumbsup:

(Dont hold me responsible if you damage anything please.) lol.

Wouldn't dream of it ! I've already lost my ECU harness virginity. No big deal now :P.

I was going to run mine via a switch so I could break the connection or return it to normal at any time. Going to label it "Off" and "Fun" lol.

That way if there is any issue with the ECU getting suspicious after a while (hey, I just don't brake, OK) it is easy to fix. Throttle limp sucks :yucky: .

so use the emanage relay outputs to disconnect the brake line signal till around 50km/h

The good ideas have been coming thick & fast the last few days. Loving it :thumbsup:

OK, so some ideas are better than others, but you catch my drift, LOL

Aaron, to clarify a little on what the Impul ECU is allowing.

First, set the Informeter to recognise 100% throttle is 4.12V

Now, When I do a launch from a standing start I get around 45% throttle till about 10kph and then I get 100% throttle.

On a stall launch, I get around 45% throttle. (But this was not done properly as too much traffic around).

But I love :wub: this solution... looking for wire cutters on the weekend.

First Andy, try this out.

With your foot off the brake for a few seconds, try and launch. Does the throttle go straight to 100%? If it doesn't, unplug the throttle body for a few seconds and try it again. Mine definitely goes full throttle from a standing start without the wiring mod.

Then snip snip. :thumbsup:

I've been seeing some references to this figure lately and 2 questions come to mind.

1) I must pull out the manual & find out how to change this setting, and

2) why 4.12V?

By my actual voltage measurements on the throttle body & driving around, each 1V equaled 20% opening as displayed on the informeter. That makes sense if its default is 5V equals 100%.

If you are saying that the throttle does actually open completely, and this happens at a lower value than 5V (totally believable), then where did this magic 4.12V come from?

BTW, the max voltage I read was 4.04V so it's not too different anyway.

Even if it is 86% it wont make any difference to the power output, we have a massive throttle anyway. It may be done on purpose to swirl the air in the plenum.

Remember that the minimum voltage wont be 0v either. It is just the range of resistance the TPS gives.

Yep, from memory the minimum was about 0.6V at (cold) idle & maybe 0.56V when warm. I think you're right - guess it doesn't really matter if not physically opened 100% if the engine can breath all it needs. However, it would be interesting to see, via a camera, how the theory stacks up to reality.

If you could find a nice clear piece of 3 inch pipe to clamp to the throttle, you may be able to see it. The throttle opens to 100% in neutral and park, also without the wiring mod. (that was the other path I was going to work down if the snip didn't fix it.)

Are you going to be right to twist the wires together if it goes into limp mode tomorrow Craig? Or just restart the car I guess. Let us know how it goes mate.

no limp mode yet!....what am I the f#$king test mule?

Yup. :P

Don't worry Aaron, I have faith in my dodgy mods. lol.

oh trust me, if anything was to go wrong, knowing this Stagea, it would've slapped you in the face just as you are about to cut it.

Just frustrating it was that simple. lol

      3D printing fun

      By Sean'O · Posted

      Howdy friends, So another weird one today, I was looking into replacing some broken clips holding the front grille for the R32 GTR (part number 01553-03831), and noticed the brackets which are supposed to hold the grille in place were also missing 😑. I do recall seeing this issue many years ago, but didn't fix it at the time. A quick look on eBay and I was able to find the genuine brackets, along with all the screws which suited the headlights (part numbers 26042-08U05,26092-08U05). Happy days!....  Once they arrived however there was an extra nut in the packaging which implied that there should also be a bolt or a stud, and sure enough, after a bit of searching I found this thread from 2013, and @Ants clearly shows a stud should be present. Reading around a bit more, it's possible the headlights on my car are the "povo pack" headlights as mentioned by @funkymonkey in this thread way back in 2008. This could explain why the studs are missing on my set of headlights. Looking at the headlight diagram I wasn't able to see a suitable part number for the stud itself. The headlight did indeed have a recess that looked like it would accept a stud, but interestingly no thread or anything obvious how the stud would be affixed to the headlight, I suspect it may have been glued in, press fit, or melted into the plastic at the factory. Another member may be able to clarify if they happen to have a genuine set of N1 headlamps. The only thing we have to work with within the recess is a keyway which likely is there to prevent the stud from rotating within the recess. In any case, back to 3D printing, I put together a model which acts like a pug with a friction fit inside this recess, making use of the keyway so it doesn't rotate while tightening a bolt. Printing in TPU will allow it to slightly swell making a nice snug fit without cracking the part. I've designed the adaptor it to accept an 20 mm M6 bolt (stainless with a cap head in my case), as opposed to the standard M5 stud and I made use of the standard galvanised split washer that came with the genuine brackets from Nissan. Once the bolt and screws were all in place, giving the bracket a gentle shake gave the classic "shaking the car" feeling, very solid, which gives me confidence this is going to be able to hold on much better than the janky solution which seems to have been here for the past decade or so. Overall I'm really pleased with how this turned out and maybe there are more people out there running these headlights without a centre stud at all!

      R32 GTS (RB20DE) clogged cat

      By GabsReDeal · Posted

      Hey everyone, This is my first post apart of the introduction. I tried searching a bit on the forum but couldn't really get a straight answer. I got the car to my mechanic as I felt it being weak. It seems that it was missing on two cylinders due to the injectors. I had all my injectors clean and the car runs much better. The mechanic also confirmed my suspicions that the cat is clogged and needs to be tackled asap. The cat rattles a bit and the hot exhaust warning frequently lights up when driving after getting the injectors clean. In my introduction I was asked about what modification I might be interested in and mentioned a cat delete. From what I was told, this is not really beneficial on the RB20DE and there are more cons than pros.  Could perhaps anyone give some suggestions on what the best course of action would be since the current cat is toast and needs to be removed/replaced anyway? I can also sometimes smell a strong smell of fuel, but I'm not sure if this is related.

      When I was replacing my pump due to being stranded in the wrong state, I went with the Deatschwerks 320lph kit. It is a direct plug in to the stock wires, harness, everything. It comes with a plug... but you can plug the OEM plug directly into this thing. https://justjap.com/products/deatschwerks-dw300-fuel-pump-nissan-s13-silvia-r32-r33-r34-skyline-c34-stagea?currency=AUD Downside: Won't actually flow that much on boost if you want to push it on E85, but it's comparable to the 040/255 etc. Little more actually.
