Hey guys

As much as i love the power fc and it's knock feature, i'd prefer a device that would flash a warning light when i'm on throttle and my eyes are pinned on the road. I've decided that the turboxs knock lite would be a good idea, link. I have a couple of questions though

1.Would running off the factory det sensor affect the reading i currently get on my power fc?

2.There are two det sensors on the rb26, which sensor should i use for the turboxs knock lite? i would assume the rear cylinders are more prone to knocking

Cheers

If you are running a PFC the cat temp or engine check light will already flash if knock exceeds a set level.

If you want something larger than the dash light, just tap into the dash light's power supply from the ECU and run something bigger. We built a custom dash in the nugget with this setup using a 12v LED pilot light.

Good idea, the fc is set at 60 knock before the light comes on, how can i set this value lower/what is a suitable value?

you need datalogit to change the knock level needed for the light to flash. 60 is a fairly good value tho, anything under that isnt serious enough to do damage as a one off thing, of course if its constantly up there then it might be a problem.

    • You Gregged a whole racetrack!?
    • Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.
    • 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!
    • 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...
