Hi Guys,

When I give my car a boot I get a noise that sounds like it's pinging but AI m not sure. It shouldn't be pinging as I use 98RON and have the timing set correctly.

I recorded it so maybe someone with a better ear for these things could tell me what it is, it is hard to hear but its like a rattle at around 3-4k rpm.
