3 is nothing

knock is the engine pinging or detonating etc...

the factory warning is set at 60, which is when the check engine light will flash on the dash...anything up to about 30 is ok. If it starts hitting over 30 you might want to get your tuner to look at the tune...

yeah. The mic can often pic up vibrations (not in the engine) and register high, keep driving and see if it's a once in a while thing or a common happening, if the later go see your tuner.

i got mine tuned by matty spry.

usually max knock i see is 18.

BUT when i redline it or go a tad over redline it shoots up to 60+...and the warning lite goes off, because he set it that way.

now he said "when u reach the redline or go over it the knock will shoot up. ignore it. its normal"

is THIS true?

The old knock reading mines been up to 133 & gets up to about 60 everyday but had ears on it with a knock detector & we hear nothing so yeah mine might registering my dog box or something else so i wouldnt worry about 3 lol. On start up knock may read a little high.

every time i hit limiter knock reads anywhere from 70 - 120. i try to stay off the limiter. Yes it is normal

go near red line in 4th or actually hit the limiter?

maybe the air is getting too hot and it is detonating a bit.

If your hitting the limiter ignore all knock readings from the limiter. remember stock limiter is 6900rpm.

when i reach limiter man. ahhh, well my limiter is set to 7300. that might be the problem. i will just need to hold back.

Hey guys, i wanted to set the rev cut to 7500 on mine, currently its at 8000.....how can i set it to 7500 on my hand commander, my tuner told me its really easy and somethingi can set up myself.

Also, i didnt know what it was set at before, and i was driving it hard once, and the car kind of jerked really badly (after going high reves, possible over 8000), was that my rev cut doing this, is it safe to hit rev cut...i guess its better than going over the rev i guess.......

Thanks:)

go to settings, then scroll to the last option which is rev. then hit the right arrow so the revs are highlighted then hit down arrow till it's down to what you want. then just hit back and go back to monitor mode or whatever you normally leave it in.

My Mates r33 would contantly register about 80knock on hard driving, the tune was spot on and great. Had a look in his engine bay and his sway bar had a massive dent in it from the intake hitting it, removed it and on full thrash he registered knock of 30. Big change.\

Knock is recorded as any metallic sound as in metal hitting metal, 3 is nothing.

Story pointless just a lil fyi

      I neglected to respond to this previously. Get it up to 100 psi, and then you'll be OK.

      I agree with everything else, except (and I'm rethinking this as it wasn't setup how my brain first though) if the sensor is at the end of a hose which is how it has been recommended to isolate it from vibrations, then if that line had a small hole in, I could foresee potentially (not a fluid dynamic specialist) the ability for it to see a lower pressure at the sensor. But thinking through, said sensor was in the actual block, HOWEVER it was also the sensor itself that broke, so oil pressure may not have been fully reaching the sensor still. So I'm still in my same theory.   However, I 100% would be saying COOL THE OIL DOWN if it's at 125c. That would be an epic concern of mine.   Im now thinking as you did Brad that the knock detection is likely due to the bearings giving a bit more noise as pressure dropped away. Kinkstah, drop your oil, and get a sample of it (as you're draining it) and send it off for analysis.

      I myself AM TOTALLY UNPREPARED TO BELIEVE that the load is higher on the track than on the dyno. If it is not happening on the dyno, I cannot see it happening on the track. The difference you are seeing is because it is hot on the track, and I am pretty sure your tuner is not belting the crap out of it on teh dyno when it starts to get hot. The only way that being hot on the track can lead to real ping, that I can think of, is if you are getting more oil (from mist in the inlet tract, or going up past the oil control rings) reducing the effective octane rating of the fuel and causing ping that way. Yeah, nah. Look at this graph which I will helpfully show you zoomed back in. As an engineer, I look at the difference in viscocity at (in your case, 125°C) and say "they're all the same number". Even though those lines are not completely collapsed down onto each other, the oil grades you are talking about (40, 50 and 60) are teh top three lines (150, 220 and 320) and as far as I am concerned, there is not enough difference between them at that temperature to be meaningful. The viscosity of 60 at 125°C is teh same as 40 at 100°C. You should not operate it under high load at high temperature. That is purely because the only way they can achieve their emissions numbers is with thin-arse oil in it, so they have to tell you to put thin oil in it for the street. They know that no-one can drive the car & engine hard enough on the street to reach the operating regime that demands the actual correct oil that the engine needs on the track. And so they tell you to put that oil in for the track. Find a way to get more air into it, or, more likely, out of it. Or add a water spray for when it's hot. Or something.   As to the leak --- a small leak that cannot cause near catastrophic volume loss in a few seconds cannot cause a low pressure condition in the engine. If the leak is large enough to drop oil pressure, then you will only get one or two shots at it before the sump is drained.

      Help! Leak coming under transmission

      So..... it's going to be a heater hose or other coolant hose at the rear of the head/plenum. Or it's going to be one of the welch plugs on the back of the motor, which is a motor out thing to fix.

      The oil pressure sensor for logging, does it happen to be the one that was slowly breaking out of the oil block? If it is,I would be ignoring your logs. You had a leak at the sensor which would mean it can't read accurately. It's a small hole at the sensor, and you had a small hole just before it, meaning you could have lost significant pressure reading.   As for brakes, if it's just fluid getting old, you won't necessarily end up with air sitting in the line. Bleed a shit tonne of fluid through so you effectively replace it and go again. Oh and, pay close attention to the pressure gauge while on track!
