Hey chumps.

Can anyone identify, what this is (see attached images), i CBF'd trying to trace it back to the ECU.

It has JECS stamped on it, if that helps.

I got rear ended about 3 months ago, got the car back, dead battery, gah, then once i got the car running it wouldn't idle, sometimes it would idle for about 30 seconds drop around 650rpm then just die, cough cough cough.

After cleaning out the AAC valve, which kind of helped it still didn't fix the issue.

Then i remembered the beater mentioning that he found a plug loose in the boot, i just ignored it, assuming it was from the antenna which i ripped out ages ago.

However i plugged the lil bastard in and what do ya know, my car idles again, however to the effect that it now hunts, which it never used to before.

But if anyone with an insight into this lil device, would make my day, because it's given me the shits.

Keep it Sidewayz kidz :D

I personally think its some sort of resistor as it has a moulded rubber backing. But i'm just spitballing.

Looks like a fuel pump dropping resistor. It slows the speed down of the fuel pump under idle conditions most likely for noise, emissions and wear on the pump. Sounds like a plausable reason for your fault thats for sure.

Have a look if there is one in your engine bay. Passenger side on the strut tower housing. If there isn't, they may have re-wired it into the boot.

Edit: That might not be exactly it, but it's the exact shape and appears to be the same size. So as above, I'm guessing it's fuel related.

ah k, my m8 who had done a rb25neo conversion in his r32 4 door, said its the injectors resistor :S, said he had to put the r34 one in for it to work.

Fuel pump dropping resister does seem to make more sense, cause it gives the same characteristics of a car that has no fuel.

All is well however, car is running beautifullly, the AAC has decided to resurrect itself , i cleaned the AFM and its not hunting any longer, and is much more repsonsive off the line now, no hesitation.

I highly recommend doing it it's made the car feel new again.

Thanks anyways guys :) Have an awesome new year!!

    • I think the concept is highlighting the various scenarios where thicker oil helps, and thicker oil potentially doesn't help and only generates heat and costs power, in turn for safety which isn't actually any safer (unless you're going real hot). If anything this does highlight why throwing Castrol 10w-60 for your track days is always a solid, safe bet. 
    • Jason should have shown a real viscosity vs temp chart. All the grades have very little viscosity difference at full operating temperature.
    • Oops... I meant to include the connector  view... BR/W - power from fuse L/W - motor negative to fan control amp (and off to HVAC pin19) OR/B - PWM signal (from HVAC pin20) B --  ground  
    • Yep, if you are applying filler it sounds like there is something wrong with the body lol. Safe to assume there is going to be a lot of sanding going on if your still applying fillers.  Picture a perfect bare metal panel, smooth as glass. You lay down your primer, it's perfect. (why are you going to sand it?) You lay down the colour and clear, it's perfect. No sanding at all took place and you've got a perfectly finished panel.  You won't be chasing your tail, sounds like you were prepping to start laying filler. If your happy with the body after the sanding, there is some bare metal exposed and some areas with primer, no issues at all, start laying the filler. You are safe to lay filler on bare metal or primer (of course check your technical data sheet as usual for what your filler is happy to adhere to).  This isn't a 100% correct statement. There is primer that is happy to adhere to smooth bare metal. There are fillers that are happy to adhere to smooth bare metal. Just make sure you're using the right materials for the job.  Typically if you are using filler, you would go primer, colour and clear. I've never seen any instances before where someone has laid colour over body filler (maybe this happens, but I haven't seen it before). So your plan sounds pretty normal to me. 
    • I don't think there's any way someone is push starting this car.. I honestly can barely move it, and moving it and steering it is just flat out not possible. I'm sure it is, but needs a bigger man than me. I have a refurbished starter now. The starter man was quite clear and consise showing me how nothing inside a starter really should contribute to slow cranking, and turned out that for the most part... my starter was entirely fine. Still, some of the wear items were replaced and luckily it didn't show any signs of getting too hot, being unfit for use, etc. Which is 'good'. I also noticed the starter definitely sounded different, which is a bit odd considering nothing should have really changed there.... Removed and refit, and we'll pretend one of the manifold bolts didn't fully tighten up and is only "pretty" tight. GM only wants 18ft/lb anyway. I also found a way to properly get my analog wideband reading very slightly leaner than the serial wideband. There's Greg related reasons for this. The serial output is the absolute source of truth, but it is a total asshole to actually stay connected and needs a laptop. The analog input does not, and works with standalone datalogging. Previously the analog input read slightly richer, but if I am aiming at 12.7 I do not want one of the widebands to be saying 12.7 when the source of truth is 13.0. Now the source of truth will be 12.65 and the Analog Wideband will read 12.7. So when I tune to 12.7 it'll be ever so slightly safer. While messing with all of this and idling extensively I can confirm my car seems to restart better while hot now. I did add an old Skyline battery cable between the head and the body though, though now I really realise I should have chosen the frame. Maybe that's a future job. The internet would have you believe that this is caused by bad grounds. In finding out where my grounds actually were I found out the engine bay battery post actually goes to the engine, as well as a seperate one (from the post) to the body of the car. So now there's a third one making the Grounding Triangle which is now a thing. I also from extensive idling have this graph. Temperature (°C) Voltage (V) 85 1.59 80 1.74 75 1.94 70 2.1 65 2.33 60 2.56 55 2.78 50 2.98 45 3.23 40 3.51 35 3.75 30 4.00   Plotted it looks like this. Which is actually... pretty linear? I have not actually put the formula into HPTuners. I will have to re-engage brain and/or re-engage the people who wanted more data to magically do it for me. Tune should be good for the 30th!
