Hi all
Just a quickie I have a my00 with downpipe and backbox (scoobysport), I can hear a small tappy type sound when accelerating hard using regular unleaded, could it be pinking?
Please help, I don't want a non-warrantied bill.

I would not think so Ron. You still have std ECU don't you Ron?
You get these sounds with the downpipe. I thought the same when I first fitted mine.

 

Yes your right Bob, I do have standard ecu, i'm just a bit paranoid about getin a big bill.
Thanks anyway.
Ron

 

Ron my 95 is std apart from the exhaust but it still pings (pink) on poor fuel under hard acceleration so yes be carefull.
to fix this i use a small amount of Nitrous Formula octane boost.

 

Try running it down to empty, fill it up with SUL and then try the same acceleration.

If there is no tappy sound - then it is pinking. Alternatives are to try det cans or borrow a knocklink and try that.

IMHO even with the standard ECU it is possible that it is knocking.

Hi Nitro, Do you actually hear the pinging or do you have a knock sensor such as Knocklink?

 

Mate my P1 was deffo pinking a while back but been safe since using Millers.
Hope this helps.

 

Thanks for that guy's
I had a word with Pete Croney yesterday, and he explained the sound is actually the waistgate chattering against the back of the turbo and not detting, you can't hear it on a standard car but it does still happen.
Was I pleased? I should co-co.
Many thanks
Ron
