detonation of turbo engine at high speed
Posted: Sat May 21, 2011 11:17 pm
I have just put an AEM cold air induction onto my 2004 SE Mx5. Induction noise is high especially when the stock BOV returns the compressed air to the induction side of the system. I have now noticed that the engine detonates at about 6000rpm. I am thinkling this is a lean fuel mix. Does anyone know if the standard ECU can be modified to accomodate this leaning off of the mixture?
