Pinging In Nuetral

Car is an r33 gtst s1 with an rb25/30 in it.

I am running a ViPEC v44 plug in ecu.

All of the cam timing is all 100000000000% spot on and I set the base ignition timing up fine also.

Now the issue is when I rev it up in nuetral, around 3000 to 3500 rpm and MAP of 80 to 100kpa (-0.2 to 0 bar of boost) the car pings.

It is a very audible noise and do not need to use the knock sensors to hear it. I have a Gizzmo Kmon set up though, not just using my ears :banana: The timing in that area is (rpm vs boost in bar):

______3000____3500

-0.2____31______31

__0____27______27

The fuel is Vortex 98. Guilt-Toy said the timing is pretty mild so I have no damn clue why it is doing what its doing. I have NO f**king idea why it is doing this and I am going to pull my hair out and torch the car. Its driving me insane.

Any suggestions?

Thanks

Lukas

I have a complex mathematical theory that only I can understand, here it is:

Latitude: 19° 15' 0 S

Longitude: 146° 48' 0 E

These are co-ordinates of Townsville and I believe there to be a god like creature in the fabric of time that is f**king with our two Skylines causing them to ping.

That is all.

This theory is also supported by Stokes Theorem as seen here: http://en.wikipedia.org/wiki/Stokes%27_the...lectromagnetism

Now explain to me how the hell I can easily understand that crap but this mystical ping eludes me.

I think this god aweful being's reach also extends to the Whitsundays too because no matter where I take the car I can't escape the ping :banana:

does it still do it if you pull timing? what are the afr's like?

and last but certainly not least, why the hell would you run that crap they call vortex? (runs from all the vortex lovers)

Because the two BP service stations here don't have 98. The only 98 in town is Vortex. Its not my fav either but its the only 98 :banana:

The AFRs are around 13 at that section of the map.

I haven't pulled the timing yet as I have been busy working and fixing another car. I have a day off tomorrow so I am going to run it tomorrow with just the 10 deg btdc base and see if it still does it. I will be making a sound recording for Guilt-Toy using the Gizzmo Kmon too so I will be sure to update the thread with any info.

you sure its a ping mate? could it be some kind of rattle coming from the water pump or oil pump or something moving around in the head?

disconnect the water pump belt and quickly test it before you do anything else

I think it is man :S I am pretty retarded and am not 100% sure how to upload these sound files I recorded. I tried putting them on youtube but no luck :blink:

I will send you the sound recordings of the two little tests.

I did one test on base timing lock to 10 btdc and then another when I let the ignition map go back to normal and recorded them both.

If someone wants to help a retard put those audio files online Im all ears.

PS It doesn't make that knocking noise when it is locked to 10 btdc

max adv is 35deg in your map on these load points. something is not right somewhere.. and this issue happaned after your removed the timing case and harmonic balancer and CAS and re-installed them.

Take your belts off and try it and get back to me.

Yeh I don't know wtf is up! I have bought a new CAS and it is in the mail express post so should be here by wednesday at the latest.

Do you think my CAS could be stuffed? The balancer shows about 35deg when I have the timing light on it and rev it up BUT when I watch the ignition table on the laptop it makes that noise when the ignition table is meant to be about 28 to 32deg. I guess I will see if the CAS if stuffed when the new one arrives.

Ok man I will take off the belts tomorrow and see if it still makes that noise. It doesn't make that noise when locked at 10deg though for some reason.

Should I just go all out and pull it all down again put it all back together again or wait to see if the new KNOWN working CAS fixes it?

Tried it without the belts on and it still made that noise.

I just pulled everything off and put it all back together and for SOME reason it isn't doing it anymore. Could have been a CAS issue, I am just glad it isn't doing it now.

NOW I have a different problem!

My coolant is showing STUPIDLY hot readings. It will be fine driving around etc and not doing anything stupid and then BAM is will go from 90 right up to 100 in about 1 second. WTF?!?!

I can be driving along fine doing 70 in 4th gear and the temps will rise REALLY fast from 85 to 105 within about 30 seconds. It is just silly.

Could I be getting electrical interference somewhere that is messing with the temp sender to the ECU?

I am trying to find a known working sender to put in and test.

It wasn't raising in temp this bad before when I had no radiator shroud. Now all of a sudden after I have put the shroud on its running stupid hot.

Any Suggestions?
