^^ very true. You would know since you just had one there lol
Lucky the sound calms down within 15-20 secs and idles out to being pretty "normal" tone Alan

Out of curiosity - any way to recreate that cold start mode on demand via coding? I know it won't have as much power as a normal map, but just for that fabulous sound imho it's worth to put it in that mode when you are cruising at low speeds around
P.S. So I'm still wondering what exactly causes that sound: open wastegates or 30 degree ignition timing adjustment? |

my 50i catless downpipes and resonators delete
[QUOTE=lowlevelhell;21400858]Interesting that they decided to forgo the flap modulators on the N63. Shouldn't take but 2 or 3 seconds for full oil pressure to reach the turbine bearings though.
A major portion of the sound difference is the "converter heating mode" in which the ECU purposely adjusts the engine timing to after TDC ad a means of throwing combustion heat downstream to rapidly heat the catalytic converter. That delayed ignition produces a much different noise, as it's accompanied by a second, latent injection to ensure ignition/combustion after peak cylinder pressure is reached. I've seen nothing to corroborate the idea of the wastegates opening on a cold start, though it makes a degree of sense.[/QUOTE Still apply if you have a custom exhaust with catless downpipes and resonators delete? need to idle thoose 30 seconds when cold anyway? |

It's loud because it can. And because it's awesome. Don't like it? Get a Lexus.

This is not the E70 forum. Sounds like a diesel or lifters.
