it looks good mate :)

ive been thinking of getting a bonnet like that for my 34 with a new front bumper ... mine are both all stone chipped and kinda need a new front bumper anyway its sagging something special

i like the one without the line in the middle though if you get what i mean..

more of the East Bear one

Yeh does look good mate, well done with the mods :)

One thing to note with vented bonnets, there is a lot of science to it. What can happen with cheap bonnets or ones that aren't properly engineered is they create a low pressure zone across the top of the engine bay, which means the air will be sucked up over the intercooler and radiator instead of through it, causing cooling issues.

Also another thing, you won't get away with the "it's stock officer" line. The bonnet is a structural part of the car, modifying it as you have done modifies the structural integrity of the whole car. Meaning it is definitely sticker worthy.

Just a heads up.

Correct!

This is why the Nismo R-Tune bonnet has a Z-Tune tube which links the bonnet with the airbox.

I didn't know this, mmmmmmm

Would I be correct in assuming that haveing a full width radiator air guide in place would offset the negative air charge?

As in forcing the air down through the IC and rad the the bonnet will "vent" the heat as one would assume it's designed for??

In God_speed's Nur Dave, he has

* R Tune bonnet (genuine) but with Z-tune tube out.

* ARC airbox (which won't accept the Z-tune tube)

* Full length air guide

> temperatures at speed are at least 4 degrees less than usual despite the ARC box being notorious for trapping heat

Wow... If that's a stock bonnet underneath and you just fibreglassed it over the top, that looks pretty impressive.

Yes my friend it is the stock one . LONG time to do it right tho

Looks cool, a little too "Big" for me, but still cool. Also, This ^. Definitely yellow worthy.

Does the opening make rain drain into the engine bay?

Nice work!

      Take the value it measured as, and pick the closest range available that is above the reading on the screen.   Also, no point just testing the coils. Read what has been said again. You need to test all your wiring, everything.

      Does the scanner do all the CUs in the car, or only the ECU?

      R34 N/a And R34 Turbo (gtt) Transmission.. Uh, Problem.

      By albyz34gt · Posted

      @666DAN sorry to bring you and old thread.     I've got my de+t done and it's all running great other than 1 small issue.    Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd when selected . But nothing when in  drive or what gear your in when you pop it into tiptronic. I'm sure there is maybe 1 wire in the ecu plug I need to move to rectify this. Do ya have any ideas?     Cheers man

      Well I recently changed my rear axles and was thinking if I bumped anything, I have been driving the car for a while now though... But it has been raining today so everything is wet under the wheel arches. Brakes feel fine and can't hear any of the metal screamers, I had a squeak coming from one of the handbrake drums but that seems to have gone away a while ago. I was going down a hill when it lit up and I did feel the abs bite for a second and question why it did it?

      ECU sees many times the speed than speedo does (R34 swap)

      By GTSBoy · Posted

      Correct. Um. I dunno. I haven't cared enough about the way that the NA cars work to know for sure. But..... The 33/34 turbo manual cars have an electronic speed sensor in the gearbox that outputs a +/- (ie, sawtooth AC) voltage signal. That is connected to the speedo. The speedo then outputs a 0-5v square wave (ie, PWM) signal that the ECU (and any other CU on the bus) sees. The speed sensor is NOT directly connected to the ECU. So here's the problem. Your new ECU expects to see the PWM signal, but must somehow be getting a direct signal from the diff speed sensor. Which would suggest that the wiring of the NA car is not the same as the turbo cars. I think you will need to spend some time with (hopefully the wiring diagram for the car) and a multimeter to see what is connected to what. Then, presuming I am correct**, you would then want to separate the ECU speed signal input from the rest of the car's wiring, and probably either buy a speed signal converter, or build one using an arduino (or similar). That would take in the speed sensor signal and output a scaled (and suitably rearranged) signal for the ECU. ** We shouldn't presume that I am correct here, because there might be something else crazy going on. I don't think you could convert the speedo to be fed from the gearbox sensor, because the pulse rate from that sensor is probably different to the diff sensor and then the speedo would read wrongly. And this also wouldn't fix the ECU's problem either, because the ECU doesn't want to see the gearbox signal direct either (assuming that they are all on the same wiring, for some odd NA related reason, see above caveat!) Does this help? Probably not. Can you make it work? Almost certainly. With the above work. You should buy a handheld oscilloscope from Aliexpress so that you can view these signals directly. Connect up the probes and drive the car. Show photos of the screen when drving at known speeds and connected to different places, and we'll see what we can learn about it.
