It was out of SAS's league, what makes you think they can do it? Even the Japanese have only hacked the fuel and timing maps afaik.

I have gone down a different route anyway, not looking for an ecu hack now as for years I have been let down. The HKS will be going in when I get back from Qld.

A bit of a pictorial wrap up of the first round of the Nulon Nationals at SMSP. Held on a wet skid pan, it's a Motorsport event that pits 9 forum based car clubs against each other in club level Motor

And here is some in car footage of the day, showing the wheel work required for such tight courses! Sorry for my fat melon being all over the pics

Stagea's paint looks bloody good Alex. Nice to see some more pics from the Stagea meet. Scrolled down for more, only to be greeted with the red crusty that fouls up this thread

I never said they "could" do it but seeing as they are both electronic engineers in software and hardware and developed Nistune, I thought I'd ask if they are planning on having a look to make it easier for us all.

Engine bay looking good PN-Mad

Intercooler is crooked.

(Hey! So I'm a little OCD...)

Must've been Craig's fault :P

It is crooked- but as you know, if you want it straight, you'd have to chop out more of the FRP bar- thus reducing strength. I'm happy for it to be a bit crooked, cause I'll never see it behind the front bar!

Nah, no extra chopping... just pick a lower hole for the bracket (near bonnet clip) to be bolted into.

Then the other two wouldn't fit....anyway- not OCD with things I can't see!

How long did your mate drive it around without a tune? Did you do anything to help the engine?

I'm planing to remove 2 degrees static timing (the limit of what I can do without the flash software) and maybe get the bigger fuel pump in there to give the injectors a bit more room up top. Just in case you know.

He is still driving it around without a tune... although the BCM is letting go so he has intermittent wipers when it is dry and none when it rains (lol!) among other electrical eccentricities.

Have one coming in so should be back to normal in less than 2 weeks, but has had no mechanical issue at all.

Only other thing that was done was a Race Radiators custom radiator installed at the same time.

Update: Fabrication of the Intercooler piping, and exhaust are COMPLETED banana.gif

Happy with the result - the turbo outlet to pipe is amazing- I'll get some pics up in the coming days. I hope to hear its voice tomorrow, with the remainder of things being assembled/plumbed/filled/tightened etc.

The HKS GT-II External Wastegate controls the boost. It has a 0.35BAR/ 5psi (supposedly) spring inside. This functions as the boost control. It will be tuned at that level, and once everything is sorted and any problems figured out, then I propose using a manual boost tee of some form to run no more than 0.5BAR. That is considered the safe max for the stock block, and nets good power, however I have see stock blocks with 10 or 12 psi holding up on the US sites.

Depends a lot on where you measure the pressure I think.

I have a feeling it will end up at about that level too, but we'll just have to see.

Meh, 7psi?

Get some e85 in the tank and dont put too much timing in, you should be able to push it to 1 bar no problem. :banana:

15psi on a stock VQ35 bottom end?

Think it'll take more than fancy fuel to keep it alive, but feel free to put your spare VQ35de in your car and let us know hit it goes Buddy. :P

Im sure a lot of the feedback on rod strength from the US is just bad tuning. Too much timing and det is what kills rods not boost, E85 will help with both issues.

I guess my motor is just super strong right? Even though the rods look very similar in size? The amount of times I have heard "dont run more than 20psi" or "dont use a p1ggyback computer" now it just makes me smile. :whistling:

x2 bad tuning kills em.

If you get det, in-cylinder pressures might go from 1000psi to 2000-2500psi suddenly, if this happens BTDC then Mr Rod has huge stresses on it.

As long as you make sure that peak cylinder pressures are reached 8-20 deg ATDC you make best power, so if the tuner doesn't get too cute with advancing things beyond the ability of the fuel to produce a smooth flame front then there is no reason you can't stuff more boost in.

QFT.

The main benefit of ethanol being it burns slower than 98, right through the crank's downward travel. Thats where the extra torque comes from.

I hope you have a good tuna picked out... :whistling:

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      By GTSBoy · Posted

      Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      By Bireley_32 · Posted

      Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!

      Mistakes were made, my R34 Story

      I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
