Yes, but there is a big difference between wanting something somehow better, and not knowing how or why, and knowing why, visualizing what should be, and finding out how. BTW, I think we need another map for cold while using your map for warm/hot.

Hey, I've tried to tweak it a little
There wasn't a single change that didn't make it worse. Next I'll try adding some timing in the DI areas.

I've just re-reduced the AVCS intake cam to 40 which has settled the knock signal and about to add in ignition. I'm not sure if it was true knock or just intake AVCS noise too close to the cam advance limits, but the engine is behaving much better with a bit less cam, more PI lower down, full DI up top. |

Too much intake advance means intake is opening when piston is travelling up in exhaust stroke. This can send exh gas up intake runner and re breathe increasing residuals and knock. So there is always a fine balance.

load > 0.90 up until 3,8k rpm or so. And there's still headroom for more spark left. Feels better than before. Seems worth to play around with these tables. |

I'm not too active on this forum lately but I did get caught up with this thread, as these things tend to die and suddenly get revived.
The AVCS intake side has the negative values @thambu19 and others were talking about because it is a mid lockpin AVCS. That means the intake side can retard, not just advance. The retard is a fuel economy thing. It's the same type of AVCS that's on the FA20DIT. In fact, it's the BorgWarner phaser technology that Ford uses on the 5.0 Mustangs. On those FA20DIT engines when you delete the tumble generator valves you need to advance the AVCS or it runs like crap without all that tumble motion in the combustion chamber. more details (mostly relevant to FA20DIT) here http://forums.nasioc.com/forums/show....php?t=2687550 |
