I forgot how sick race gas is in the sunmer time.you can litterally hear the engine running more timing.it sounds raspy like a na m3.

I just made a video of my whole second gear blinking the tc till 80mph

AWOL

It was my understanding that our cars can only adjust timing up to 95 octane

AMGPilot

The timing map is set up for max timing, then the engine listens to the knock sensors and pulls timing as needed (up to 12 degrees max) to prevent det.

Our ECU's cannot "advance the timing" they can only choose not to retard it

Since our gas is so crappy compared to the rest of the world they usually only use 24 Degrees as max timing...

I should of said it better.the car is running the max timing my tune is mapped for.the car feels like its wi ter.

Curious why VP 109 and not VP C10?

skratch77

c10 is good but motorsport 109 will make more power.104 vs 109 oct

here is a quick video,you can hear the boost bypass tb blowing off the boost.

While I know that what you said is correct, most cars will still have two maps, one for high octane and one for low octane ( don't know about the E55, but almost every car I've tuned is this way. ). If the ecu is constantly listening to knock ( or rather, constantly retarding large amounts of timing ) then it'll switch to the low octane map to try and eliminate it. The E55 may not be this way though so you can correct me on this since I've never tuned an E55.

Car sounds awesome, skratch.

Man, I thought you'd never stop turning.
