My engine pings slightly when it's hot and when the oil temp reaches 220F, not under. My PC-V doesn't allow to add fuel by temp, only by rpm and throttle position. If I add fuel by rpm range, which I could, I'll be richer when I don't have to.
Am I the only one with this issue and how would you address it?

 

you have tried higher octane fuel ?

can you retard ignition timing ?

does it do it cruising, accelerating ?

what happens with-out the PCV ?

First of all, I'd try a different brand of gas. Sometimes a different brand will help with pinging issues. If you don't want to add fuel in the PC V table, you can always pull timing in the affected area of the map. Personally, I'd rather add fuel than pull timing. You'll lose some power pulling timing, not so much by adding fuel. Have you considered adding a oil cooler?

 

Ditto on the gas. If I fill up using a gas station near work then I get pinging like crazy. But if I use one near home it runs good. I also try to use a pump that has a different hose for each grade of gas. Since I am only getting 5 gals I want it to all be high octane.

 

I only use 93 gas so I don't think gas is the issue. I get a ping regardless what brand I use.
I have an oil cooler and 220F for the oil isn't that hot.
I will add 10% gas >2000rpm and >40% throttle and see what happens. It does it only when I accelerate, not when I cruise at a steady speed.

Thanks guys.

 

Mine does the same thing. All the way down I10 from N'Oleans all the way back to home in Florida. Got gas from many different places and octanes. It cruises along fine but when I accelerate to pass it would ping away. I have a pc tuner also. Let me know how your changes work!

 

I too only use 93 octane. Do you always purchase your gas from the same vendor? Sometimes it is as simple as bad gas.

 

I purchase gas whenever I need on the road so it's not from the same vendor but it pings regardless of the brand.
If it was bad gas, the bike wouldn't run good when cruising. It runs fine, except for this slight ping at acceleration and ONLY when the engine is hot.
I'll add gas in the A/F mixture and see if it fixes the problem.

 

At what point is this happening, is it possibly a "lugging" issue that can be corrected with a simple downshift.

 

Had this issue once before, filled up at diff gas station and no problems since.
