What does detonation sound like?
Hey, when I accelerate I hear a funny sound from the car, like some little pops.
Now I have my S-AFC set from -9% to -14% in the Low Throttle position. When I brought everything back to 0% the sound dissappeared.
Could that be detonation? I've got an n/a so I dunno!![Confused](https://www.rx7club.com/images/smilies/confused.gif)
Thanks!

There are two kinds of detonation, mild and severe.
Severe detonation is loud, and very noticable. It sounds like a loud "*****!".
Mild detonation is a little more difficult to detect. It is often described as what sounds like popcorn popping.
You're S-AFC settings are way too low, and you are probably detonating the engine. Best increase your fuel before you damage something. BTW, A/F guages are NOT a reliable way to tune the car. I have shown full rich on my guage, yet have been clearly detonating the engine...

Start your lawnmower up and spray starter fluid in its intake at high throttle. That is pinging, knock whatever. With just a little luck you will destroy the engine and not have to cut the lawn the rest of the year.
