Ok so this is the problem.

Took off in first, snapped second and the car cut out.

Started and stalled the car for 200 metres to get it off the road. (not fun on a main road at night in the wet)

Check the engine and found the cooler pipe from the throttle body which goes to the hole under the battery had pooped off. (greddy type m intercooler)

cool so put it back on started the car and now its missing but not really stalling

it misses at idle and under load

I thought I could have fouled the plugs so I gave it I kick in the arse to clear it out

no good still missing

took off AFM while engine was running, car cuts out,

started the car with AFM off, high idle missing is a little better but still there

drive the car home, missing at all RPM barely drivable

Mods on the car thats relivant

r33 turbo

greddy intercooler

3 inch zurst

12psi

greddy profec b spec 2

fuel pressure gauge

air fuel gauge

volts gauge

Here is some extra data

1. I always get popping from the intake manifold when I cold start and backfire between gears so just im guessing the backfire could have caused back pressure and the cooler pipe to pop. This is probably a timing/tune related issue but something to add anyway.

2. the last thing i did to the car was reinstall the fuel pressure gauge sender

So what could have caused the problem?

Is the missing the result of the problem or the cause?

Ideas so far

1.plugs are still fouled (clean, test) but wouldn't have caused the pipe to pop

3.coils? Pull 1 at a time to test for change

basically my mate and i drive 35kms to work together everyday and he wroteoff his 180sx to weeks ago so we are carless unless i can find a solution

Please help

Your pipes popped off due to bad clamp or weak wrist while tightening clamp.

your car runs like crap now due to the 200m of driving worth of fuel that was dumped on the plugs with no air to mix with.

resolution.

1.) use better clamps or use wanking hand to tighten clamps properly (this hand will be stronger).

2.) buy 6 new NGK copper plugs with 0.8mm gap and put them in (wanking hand tightness not required for putting in plugs)

as for your other little problems.

you have a car with an ecu that was tuned SAFELY for 10 psi through a turbo of size X

you now have 12 psi crammed in to it through a turbo that flows 15% more at same boost levels as stock turbo.

I'm sure a remap/chip would resolve the little misfires up top etc.

speak to Toshi or CEF11E from these forums for remap options.

thanks for being so candid hahaha im still laughing.

i got a new set of NGK Coppers BCPR6ES to go in tonight (fingers crossed)

i did give it a good pumping for a couple of minutes afterwards but maybe there stuffed

at $3 a plug i dont care. hehe

as for a remap ive had a pfc and hand controller sitting in my shed for 6 months now.

im trying the get the money together for a major service, tune and to put my hks cam gears in.

im nearly there so hopefully your right.

ill test tonight a post results.

thanks guys.

plugs will fix it. reason being is that because the cooler pipe popps off no air goes to the engine and the injector is letting in heaps of fuel with fowles the plugs.

So you dont have a tune for the r33 turbo?

thanks guys for your input.

6 dead spark plugs later and the car is flying again. i had the some ngk plugs in it before but they were 7's. the 6's are smooth as.

very happy

yeah still need cash for PFC tune but i still made 180kw atw on the dyno so still a healthy figure.

My cars intercooler piping popped off a while back, I put it back on and things went alright. It came off again, and again.. til I bracketed the bastard from coming off anymore.

I drove the car to a crash repair shop to get some work done and when I went to drive it out, the car wouldnt start. Theres fuel going to it, but just no bang! :P

Could this be the same problem? And is it the same thing that I need to have a look at? :)

Sorry to ask in this thread but its basically the same concept.

Cheers...

id def have a look at it but what work was done at the shop, was any pipes taken off???? does your car normally have cold start issues??

If your using what we call here in the states.....WORM CLAMPS......... then you may want to run a bead around the ends of each pipe so the clamps have something to bit.

Or put 2 clamps on the pipe/coupling thats popping off

When I said bead I ment weld bead...

But worm clamps are :D

      RB20DE NEO smallbox clutch.

      By Kapr · Posted

      For once a good news  It needed to be adjusted by that one nut and it is ok  At least something was easy But thank you very much for help. But a small issue is now(gearbox) that when the car is stationary you can hear "clinking" from gearbox so some of the bearing is 100% not that happy... It goes away once you push clutch so it is 100% gearbox. Just if you know...what that bearing could be? It sounding like "spun bearing" but it is louder.

      Yeah, that's fine**. But the numbers you came up with are just wrong. Try it for yourself. Put in any voltage from the possible range and see what result you get. You get nonsense. ** When I say "fine", I mean, it's still shit. The very simple linear formula (slope & intercept) is shit for a sensor with a non-linear response. This is the curve, from your data above. Look at the CURVE! It's only really linear between about 30 and 90 °C. And if you used only that range to define a curve, it would be great. But you would go more and more wrong as you went to higher temps. And that is why the slope & intercept found when you use 50 and 150 as the end points is so bad halfway between those points. The real curve is a long way below the linear curve which just zips straight between the end points, like this one. You could probably use the same slope and a lower intercept, to move that straight line down, and spread the error out. But you would 5-10°C off in a lot of places. You'd need to say what temperature range you really wanted to be most right - say, 100 to 130, and plop the line closest to teh real curve in that region, which would make it quite wrong down at the lower temperatures. Let me just say that HPTuners are not being realistic in only allowing for a simple linear curve.

      I feel I should re-iterate. The above picture is the only option available in the software and the blurb from HP Tuners I quoted earlier is the only way to add data to it and that's the description they offer as to how to figure it out. The only fields available is the blank box after (Input/ ) and the box right before = Output. Those are the only numbers that can be entered.

      No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.

      God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
