sorry for upping this old thread, but i'm having some questions.

I've applied buckers tutorial to my AP Stage 1+SF+TIH+IC map with a noticable difference in part throttle area of driving, it seems more 'smooth' in driving.

But offcourse, i also want to edit the ignition table because there you will really notice a difference.

But i'm having the issue that the difference between the @Bucker exmaple table and the COBB OTS table is very different. At higher load bucker adds up to 6* of timing in comparising to the OTS map.
This, in my point of view, seems an awfull lot of difference

Should i copy paste this and take the chances, because bucker is telling in this sheet that these setting alow for consistency every time...?
For now, in a WOT log, no knock is found, just rarely a short 0,35 around 3500-4000rpm.

And if i adjust the no knock tables to knock tables, bucker tells you to set them 2* lower, is he talking about the complete table, or just higher load regions?
Same for the max ignition tables, they should be 2* higher, is that the complete table, or just higher load regions?

Sorry for the noob questions, i'm trying to learn and read a lot about ignition, but it is hard stuff to learn, so some pratical help is always welcome.

This will probably take care of most of your questions:
Ignition Timing and General Tuning

Short answer, depends on your mods and fueling. Stick to the table regions you are targeting. Generally, you should leave the mid throttle area alone as the ECU logic is trying to advance timing constantly for fuel efficiency.

When raising timing on pump gas (I'm referencing US 91 or 93 octane here, not sure what you guys are runing over in NL), go up in .5* increments on No Knock tables. Look for KR. If KR starts to consistantly present itself, back it down. Keep Knock tables lower than No Knock, but raise their values along with the No Knock tables so timing will be pulled during a KR event. 2* is safe as long as you are only going up by 0.5* at a time.

Thanks,
I've been reading a lot the last 2 days and have learned a lot since then about the logic behind ignition timing. But offcourse i'm not even nearly there when it come to fully understand all of the logic

As far as i could find, these settings Bucker presents, are save to copy paste in my car (i only have mild mods as stated in my signature)

Here in Holland we're lucky we have very good quality fuel, i'm using nothing other then octane RON 98 ( i believe this is AKI 94 over in the states?)and we can even get octane RON 102 closeby in Germany

I have applied Bucker's ignition timing today and so far so good, driving with the AP shows no knock up till now, and i noticed the car has become very very smooth in driving, very smooth in part throttle as well as a little WOT as far as i could

All in all, this guide changed my car to a very smooth driving and smooth accelerating car, so big thumbs up to you guys for putting all the effort in teaching and helping others getting on with self tuning their car.

I hate that I have to come back and show this, but I just learned something new about the no knock tables
