Dumb Question: Pinging
 

i did a search but couldn't find this question.

does pinging occur when you lay off the gas or when your accerlerating?

i'm curious becuase i havent heard the 'marbles in a tin can' but when i am laying off the gas with the car in gear it seams to pop/rattle the exhaust a bit. i'm thinking it's just the section of piping that i havent upgraded yet, but i'm not sure.

any help would be appreciated

detonation is cause by heat so your car usually only pings under acceleration

ok, so it's just my lack in money which is causing this thing to sound like backfiring.

Re:Dumb Question: Pinging
 

my car is backfireing like a bitch 2. i only have a header and short ram both of wich are temporary tho. i gotta get the money up 2 get my exhaust made. but it pops like crazy and even almost stalls but never does. maybe my timing is off or some ---- but its 2 cold 2 be playing with it.

Re:Dumb Question: Pinging
 

your timing must be off like a sum bitch with that little done

Re:Dumb Question: Pinging
 

yea it prob is the timing but like i said its way 2 cold 2 mess with it right now. my car isnt even registered yet so there is no rush

Re:Dumb Question: Pinging
 

There was a question about pinging like a week ago, I gave a huge explanation about it. SEARCH!!!!!!!!

But yes it is caused by the heat and the feul igniting before the spark plugs spark, this is why it pings when you lay on the gas. Lower grade fuel will always ingnite sooner then higher grade this is why you have to use higher grade fuel with turbo apps!

Re:Dumb Question: Pinging
 

i did, but nothing about my question was ever brought up. hence why it's a stupid question...

i run 93 octane so i assume that pinging should be non existant correct?

Re:Dumb Question: Pinging
 

what is your setup? n/a turbo? what fuel managment?

Re:Dumb Question: Pinging
 

If I remember correctly you are running TE. Have you had a chance to tune it yet?
