ignition advance map zeroed

I also bumped up my knock correction, so if I get knock I don't break anything, but my timing is perfect so it's more of a fail safe for bad gas.

I am far from an expert. Just some suggestion for what it's worth.

In my experience, if you don't have any signs of knock correction under any circumstances, you are leaving a lot of power behind.

There are so many different scenarios where knock correction may or may not be present (gear, temperature of internals, atmospheric conditions etc.). Personally I have my timing set high enough that I in certain scenarios have knock correction intentionally. That might e.g. be in 4th gear and/or if the engine gets really hot. That means that max timing is available in lower gears and/or when the engine is running cool (street driven). If the engine runs in higher gears or hot (track), I let the ECU pull timing within reason (max -2 deg FLKC target).

I frankly don't get the point of putting all timing in Base Timing B, instead of splitting it up in the two tables and let the ECU have all available knock correction strategies available?

If you don't like the stock split between BTB and KCMA, you can instead simplify it and make it fixed values for each load column in KCMA (i.e. the way Wayno did it in his tunes). That makes BTB easier to look at if you are using RomRaider. Or you can copy the values out into an excell sheet and add them up to see total timing there. Or copy the added values back into a "look only tune".

Agree, i dont see the point in intensionally disabling a safety measure for no gain.

When iam drops it can not only be isec to reduce riming but it can also add fuel to surpress Knock
