Yes you got some knock on cyl3, others are fine. You can still add more timing at lower RPM's.
You can also see average knock to see how much to pull from base map...
This ME7 variant does not have per-cylinder timing maps IIRC, so not much else to do.
It's meant so that KRA will take care of the differences.

So average ignition retard knock control is 0.75 after 5500 rpm, fnwue is 1 until 4750 rpm. Based on that should I pull 0.75 timing from KFZW after 5500rpm, and add some timing to KFZW2 before 4750 rpm? I'm thinking 0.5 or 0.75 degree increments are the best way to make adjustments now? cheers |

Yes, you are on the right track! It is good to see someone learning quickly. |

Thanks haha, just very cautious as I don't want to blow it up!
Once ive repeated the process to get knock then dial it back etc, that would mean that timing is 'done'. Is there then anything else worth looking at bearing in mind that apart from a larger TIP and cone filter the car is standard?
cheers

I would avoid any cone filter crap. If you want to do intake mods, you can cut holes in the bottom of your airbox. Open air element filters mess up MAF readings. TIP is unlikely to do much. Your next step is bigger turbo or a 2.7t  |

Doing anything with airbox is pretty much waste of time on these, the turbo is the main chokepoint.
Even the intercooler on them is half-decent for the boost they run.
And the problem with a bigger turbo is, that even with a GT28RS and like 1.7 bar with no knock - it already starts to bend the rods...
So really, the best thing is to just to do the remap as well as you can, and if you need more then you need to do a full on project car with engine build, intercooler, exhaust and turbo.

Unless spicy parts come up cheap and local I dont think I will be going too crazy really.
Is there any other optimisation to be done on the map once ignition is sorted? Or is fuelling/boost/ignition pretty much it for 'stage 1'?

I have not looked at all your logs, and ... I don't think I have time to.
But I always put a 4 bar FPR on these, because injectors run out before the turbo does usually for me.

So you can push the boost up to the point where the injector duty cycle is maxed (hence the 4bar fpr), but still be ok in terms of torque etc with standard rods?
Like knock with ignition, would EGT be the guideline for working out how much boost you can safely run?
Im pretty happy with where the car is now but its all really interesting, glad Ive got involved

You can run the turbo flat out after 4500-5000 rpm at 95% wgdc.
But you need bigger injectors or 4 bar fpr.

Is it worth working on IMX to fine tune the boost so that actual is as close to requested as possible?

Your next step is bigger turbo or a 2.7t Bigger turbo is always a god choise, but IIRC K04 coud make more boost.  We need a compressor map. BG |

I have been working on getting requested boost and actual boost to align more closely, and also still looking at optimising ignition.
I have a couple of questions:
Regarding the ignition, in the KFZW2 table for below 4700rpm, is it worth advancing this into knock to then pull it back slightly? I have already added some advance and still not seeing knock retard. I have some knock above 5500 rpm which I will make adjustment for in the next upload.
Based on my boost logs, it is worth it or in fact possible to get requested and actual to align more closely? I have been making small adjustments to KFLDIMX and have reigned it in a bit so far.
Appreciate your thoughts, latest log attached (2 runs)
cheers!

yep bring imx closer to wgdc pre-lin or bring req boost up to actual. |
