Hey SAU,
I am having trouble with engine knocking. I have tried a 500ml bottle of Wynns Octane Booster, which claims to stop engine knocking, and there are still knocks. I put the booster in before i filled the car up, drove around slowly for a few mins to help mix it through the tank (like going around roundabouts, swerving side to side down the road *like the racecars do when they warm their tryes*) and still get the knocks.
When i start the engine, there are 1 or 2. whenever i try put my foot down, the number shoots up to about 30-40.
I have to drive 4 hours home tomorrow so i am hoping to get some help by then.
Things worth noting:
I have recently had the battery disconnected, and a larger battery put in.
Before i put the octane booster, after i put the foot down i had 58 knocks. So, the booster helped a little but there are still problems.
I have the following mods- Apexi power fc, apexi boost controller, 3inch turbo back exhaust.
Only run 98 shell V power
The car is on stock boost.
Cheers,
Lachlan
