Engine pinging (rattle noise) under acceleration - Page 2 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Yep, the H6s were the worst of the NAs. The B4 Liberty was shocking, as were the early STis.

There will be no material incompatibility with Ethanol. I've seen the stuff about "chirping", but that's an annoyance more than anything.

I'd suggest you try a tank and see. If it chirps instead of pings, that's a massive improvement.

That's correct.

Easiest way is to be cruising in 5th gear and within the rev range of 2000-3000 and back off to 0 throttle and then apply throttle. You can apply full load but I can hear it even at say 10% load on the throttle

I assume their fix was a massive detune ?

It will take me sometime to drain the petrol as I just filled up last night with bp98 with octane booster but I'll run the idea across with the service guys as well as I don't want them to come back to me and say something like oh you used 100ron so we will void your warranty or something like that =\

Actually wouldn't running octane booster and 98 will be the same?

Try let the car sit in the traffic for some time as temp will rise and even easier to reproduce pinging. If someone has dashhawk you can monitor the ping level digitally with exact level of detonation.

I've got 600kms on the clock now, and I cannot say I have heard any knocking so far...

If you could grab an audio clip of it that would help, I'm not good with sounds :P

But I'll specifically try the 5th gear 2-3k off-on throttle tomorrow on my way to work though.

Fingers crossed nothings up! This is the first I've heard of it on the interwebs hmm might be an aussie problem :S

Took it out for a quick test, Turned off the music and AC - i didn't hear any pinging or anything out of the ordinary. Tried in gears 2, 3, 4 and 5. If only we could get an audio clip of it in case i do start hearing it...

JiB · 08-06-2012, 09:08 AM

Just got back from my test, nothing sorry.
but i have noticed another problem, i will start a thread

Visconti · 08-06-2012, 09:13 AM

With hard gear changes I've been seeing these cars ping. Nothing else

proficience · 08-06-2012, 07:52 PM

Gave it a go this morning on the M4 - couldn't hear anything out of the ordinary...
Tried in 5th and 6th ~2.5k rpm - nothing.

Doesn't sound too good for you ...

sho · 08-06-2012, 07:56 PM

What fuel are you using?

I am hoping this is purely a fuel issue.

Man I keep forgetting to jump in your car to hear this pinging sound.. Still no pinging sound for me so far
