Mr Pops Posted January 21, 2012 Share Posted January 21, 2012 probably the engine timing too advanced, hence the rattling or "pinking" from the engine Yep i would go with this too Link to comment Share on other sites More sharing options...
Dardandec Posted January 21, 2012 Share Posted January 21, 2012 Defiantly sounds like its pinking. Used to be a common problem on older cars with old style ignition systems when the ignition timing was too far advanced. Modern ecu controlled cars have a knock sensor which detects pinking and retards the ignition timing automatically in that situation. As its been stage one tuned the knock sensor could have been immobillized or its settings adjusted hence the pinking noise. Link to comment Share on other sites More sharing options...
Tradescanthia Posted January 21, 2012 Share Posted January 21, 2012 Serious rattles/rumbles develop over a period of time. I'd go along with the 'pinking'. Modern petrol is low octane, tuned engines need high octane. Return your car to its original state of tune and start again. Link to comment Share on other sites More sharing options...

returnofjim Posted January 22, 2012 Share Posted January 22, 2012 If the rattle has happened since you had it mapped then take it back to the garage it was mapped at. Link to comment Share on other sites More sharing options...

Guest brownd95 Posted January 22, 2012 Share Posted January 22, 2012 one other thing guys, i was listening to different sounds people were getting on youtube. It sounds to me like cogs making noises like ball bearing in a tin can maybe cogs missing a tooth or crunching??. not a rattle like the cat shielding. like the flywheel or something?????
