I too have been running this code for a while and haven't had any blown fuses or exploding coils or any other surprises except traction loss.

Run into a slight issue. When flat shifting, ECU is picking up a lot of knock from the missfire. It's pulling out 12 degrees due to this, which then takes a few seconds to then advance.

Shift faster?  I haven't noticed this to be an issue. Wonder if there is a "knock control timing advance" variable in ram that can be decremented to force the knock control to restore full timing right away. |

ECU is picking up a lot of knock from the missfire. Do you log knock directly or by seeing ignition moving to late angels? |

I can see the correction factors shoot up as soon as the ignition cut happens, and the ignition angle drops.
I've now set the duration back to 200ms from 600ms. Much better like this, still shifts as well but only get 6-7 degrees retard.
It's still too much though. You can see as the rpm increases it gradually recovers as knock is no longer detected. I will force it to recover more quickly and see how that goes, but it's not ideal. What we really need is for knock control to be disabled when clutch switch is acticated - one for Setzi?
Jason, have you actually taken logs of you flat shifting through to 5th gear flat out?

what you meant was: 130mph flat-out
lmfao... this thread is classic.

I wish I had "proving grounds" for that. I only have a few 1-2 logs and maybe a 1-2-3 log. |

Try doing a 30-130 if you can.

I had to have my misfire counter disabled in order to run this.
You can still log the channels and watch the counters increment with it disabled, however it is done by Eurodyne. they just reset fast before an overflow, which triggers the retard I am guessing.
A temp misfire disable would be slick.
Just re-enable it when you need to log misfires for any reason and turn the functionality off.

Missfire and knock detection are two different things. Missfire detection isn't active on Euro spec cars.

I made several shifts 2-3rd with full throttle NLS and I noticed -12 retard in one instance. There was no abnormal activity from knock sensors so it muis be misfire detection kicking in or something.
I had no time to dive into more assembly on ME 7.1 so I cannot contribute anything constructive to this "issue".

I still haven't been able to resolve my component protection issues. Well, to correct that, I haven't had time to.

Ok, this morning I confirmed the extreme ignition retard. I wasn't data logging but it was very apparent when it happened.
I will drop to 200ms and try it.
One thing I will say is that I would be hesitant to disable or "reduce" any of the knock control effectiveness, as increasing loads in the new gear has always been an area where my car likes to ping.

Does anyone have any idea how this function can be implemented in 1.8T ECU?
