Yep, you're on the right track... post your full logs and I can take a peek time permitting.

Here is the latest log, im pretty sure everything looks good, a bit of guidance on how much ignition advance to try would be very much appreciated, cheers!

So, if I take the areas if the table I highlighted in a previous post, modify them by +6 maybe? Log again and check for knock retard, is that a good starting point?
Am I right in saying that nothing should explode as the car will protect itself via knock retard?

I would say +6 is quite a lot.
And keep in mind of ignition advance and RPM effects.
Add 1.5 degrees in lower rpm range, 2.25 in mid-tohigh and 3 deg on high rpm range.
Then log. If you have no knock, repeat, log again. Back off timing in those places where it starts to knock.
You should tune it to not have any timing correction during short pulls. It is ok to have 1-2 knock events during the pull on a longer one, say 4th gear pull.
Doing +6 is pretty harsh, I wouldn't add that much at a time. Small steps, your engine will thank you for it.
Keep in mind KFZW/KFZW2 (KFZW2 active during inlet cam adjustment), while you still don't know what you are doing, it is smart to keep the factory curve, and just shift it.
Another thing is - don't run off the edge of the map, as in, your KFZW's last column should always be less than your maximum desired/actual load, so it retards timing when you have overshoot....
Keep in mind that boost and fueling affect timing, etc... I usually tune timing last.

Really appreciate the advice guys, thanks! One final noobish question before I start editing the maps, do I perform the same adjustments (proportionally) to KFZW2 that I do to KFZW?

Sure, but only one of them is likely used in high load areas where you're doing the tuning (see NWS) |

Log fnwue and you see where KFZW is used and where KFZW2 is used. KFZW is used when fnwue is 0 and KFZW2 is used when fnwue is 1.
FR function ZWGRU, subfunction ZW_NWS.

Do you recommend doing this logging first before applying and trying the changes to the ignition tables?

You need to type less and do more... fnwue should be in your template by default. It's just as important as rl_w and nmot_w to understand where you are in the map. |

You should tune it to not have any timing correction during short pulls. It is ok to have 1-2 knock events during the pull on a longer one, say 4th gear pull.
I added timing per the advice above, and have attached the log. I'm wondering if I'm not logging the correct field to properly display knock, either that nor I'm not sure how to interpret what I have. On ecuxplot the field 'Ignitionretardcyl3' is I think showing a timing pull, would really appreciate some guidance on whether I need to pull the timing back a bit or if that is acceptable. Cheers! |
