Pinging

[Tokyo Geoff]

I noticed my V35 pings quite a lot. I had it tuned by a very trustworthy guy who worked on my Zed and pinging in a turbo engine is a real worry but not so much in an NA. Anyway he said the computer on the V35 has everything tied up so he can't adjust it.

Has anyone else noticed excessive pinging?

cheers

I was in a roundabout in Sunbury yesterday and I momentarily about to start but saw a car that suspectly going to turn my way so I brake, then saw the car wasn't, so I accelerate again quickly and had a tyre chirp than a rattling kind of noise ta ta ta ta, is that the one you're talking about? or is that my ESC turning on? it's happening too quick I didn't have chance to look down and see if my SLIP light was on as it's too dangerous to do that in the middle of a busy roundabout.

Did your mechanic check the timing Geoff? Is the timing adjustable by rotating the CAS like on the Zed or is that also controlled by the computer? Shouldn't be out of whack I know but it might have been fiddled with by the previous owner. And I assume you are running with 98 octane fuel.

if anyone fiddled with mine it will most likely be Nissan dealer doing the 50000km service.

does anyone have info if the timing on V35's VQ35 is the same as local 350Z ? as I suspect nissan would have used 350Z's data to perform any engine related service.

hey mate that is just your traction control / VDC kicking in.

has happened to me a few times as well when my previous tyres were bald and in the wet

I seem to get pinging on mine a bit too... haven't quite figured out the cause. Seems to happen at low rpms when the car is coasting in gear then i get back on throttle...say under 2k rpms. It also occasionally happens during same coasting in gear to back on throttle but over 2k rpm so e.g. 2400 rpms. Anyone noticed these cars are really sensitive to heat ? Or is it just mine lol =/

Turn it off and make some smoke...

[Stephen Thorpe]

Pinging normally occurs in the heat and with high compression engines (turbo) however it can sometimes be reduced by a little less timing advance.

Not a good thing in any engine really.

Or perhaps using the wrong type of octane fuel?

Yes, sorry I thought that would be obvious...

I get exactly the same symptoms as Touge Kyousou above but in a VQ25DD engine...

[rs73]

in that case I have not experienced the pinging...

although it happened like a rattling engine sound 1-2 second after the car haven't been started for 2 days.

is that cos there's no oil in the valvetrain/head?

Correct - that is the lifters you can hear
