Hoping the shorter pipes and lack of leaks might get me bit closer to your response Andy :whistling:

Goes in this Friday hopefully its all sorted and it can see the 25 psi im so longing to see!

Pressure tested my new setup and it came up trumps!:worship:

Sure do :banana:

We finished tuning late last night, changes were:

The exhaust: it was changed from 3 inch with cat to 3.5 without.

Diff: The car now has a 3.5:1 ratio 350z LSD

ECU: I ripped the Emanage/Vmanage out and slotted in the HKS Fcon V pro.

Fuel was still Eflex e85, boost was capped at 25psi due to it not making any more power over that point. It seems the compressor is maxed out.

I haven't been able to drive it in anger yet, low down it is much more responsive due mainly to the diff. The exhaust works great keeping the Varex valve shut until boost hits for quiet cruising.

Nice work Scotty, as usual.

Out of the 3 things you changed, what do you think gave you most of the extra power; exhaust, diff or management? Or were all three neccessary to progress over what you were running previously?

What extra control does the HKS system give you over the E-manage?

Whats the differences between the red and blue runs on the graph Scotty? I notice one makes more power and less torque than the other...

How did you go tuning the F-con? Much better than the Emanage?

The Fcon gives me standalone control which is the main reason I went down that road. Now I can adjust most aspects of the tune like cold start, throttle, idle speed etc. It seems quite comprehensive from the little I have played with it.

The exhaust was where the gains came from, I ran it in 4th this time thanks to the lower ratio diff, that's why the torque was down on the last tune.

The two lines were different boost levels, I think it lost power with more boost so we dropped it back down.

you might be interested in this??

I'm sure it'll be fine; hardly any sand would've gone through that engine at the 2 min mark; what with the comprehensive air filter system he had fitted...whistling.gif

there are heaps of them in that video. most of them don't crash

i was just amazed at how quick they do an up-hill 1/4 mile~~!!

You're not wrong; that last one basically looks like a Patrol with a doorslammer engine!

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

      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...
