I found on my gtr apexi djetro on a low load ping read about 20. I occasionally still get over 100 on crank I presume from starter motor mesh? The base ignition map has a lot of low load advance. After some fiddling now I never get more than 12. Reset max timing to no more than 32 (was 48) and varified number with timing light. Bp98 always used.

I've heard plenty of RB engine's ping at low rpm high load and the knock sensor hasn't reacted, thats tuning with either PFC or factory ECU. I wouldn't recommend tuning based off feedback from the OEM knock sensor, use it only as a guide along with a proper chassis ear and good understanding of what an engine does when it is detonating.

Rebuilt engines with power FC?

^^ Spot on, definitely the best advice.

The two better tuners locally to me both use 'knock box'.

What hardware are you guys going to? Phormula?

Ive been using this system for awhile now. But havent seen much press on it.

but today i came across this great spiel on it from high performance academy..

Justin, ive found the knock box to be the most reliable as a full time tuning option as it can be quickly swapped fom engine to engine easily.

The PLEX unit is awesome but is actually painful to use. It takes a long time to set up to get the same accuracy as the knock box, therefore we only use the PLEX system on big budget big HP setups where the customer is happy to pay for the extra time.

I was informed there was a few broken links to the sound files so i have linked them to the reseller of the knock box who has some great examples.

Those are great samples, thanks Trent. Sounds like very heavy det too, nasty. Would be interesting to hear varying levels of knock starting with very mild.. eg start from knock-free baseline and then adding 2 degrees in timing every 5 seconds and then train yourself to listen for light knocking as well.

On another forum they are saying that if you use ~original at the end of the link then it works again Trent.  I haven't tried it but several have vouched that it works.

But Photobucket will probably end up closing that loophole eventually as well.

On another forum that I frequent, Street Triple, I informed the admin guys of a workaround for the Photobucket ransom demand.
The dodge was to place the string ~original after .jpg in the Photobucket URL.
Using that, they were able to download all the pictures.
They then modified all threads that used Photobucket links to point to the downloaded pictures that were now stored on their server.
The resulting pictures are stored in a gallery, which is now used instead of Photobucket.
Kudos to that site's admin people.

All the embedded photos are with photobucket, due to a recent owner change they have decided to charge for hosting (399 usd a year)

 

if you use CHROME this work around will allow you to view allthe missing images.

    • Hi all,   long time listener, first time caller   i was wondering if anyone can help me identify a transistor on the climate control unit board that decided to fry itself   I've circled it in the attached photo   any help would be appreciated
    • I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!
    • I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.
    • The hydrocarbon component of E10 can be shittier, and is in fact, shittier, than that used in normal 91RON fuel. That's because the octane boost provided by the ethanol allows them to use stuff that doesn't make the grade without the help. The 1c/L saving typically available on E10 is going to be massively overridden by the increased consumption caused by the ethanol and the crappier HC (ie the HCs will be less dense, meaning that there will definitely be less energy per unit volume than for more dense HCs). That is one of the reasons why P98 will return better fuel consumption than 91 does, even with the ignition timing completely fixed. There is more energy per unit volume because the HCs used in 98 are higher density than in the lawnmower fuel.
    • No, I'd suggest that that is the checklist for pneumatic/hydraulic adjustable systems. I would say, based on my years of reading and complying with Australian Standards and similar regulations, that the narrow interpretation of Clause 3.2 b would be the preferred/expected/intended one, by the author, and those using the standard. Wishful thinking need not apply.
