After start timing Advance BDTC?

I am curious about this table ..

Is it for cranking or a warm-up idle table?

I believe this is the amount of timing added during warm up.

Thats correct. Because its 'after start' or after cranking. It should display the same timing on consult gauge as this table during warmup until hits certain temp

Thanks ...

So this is the 'mother' of all cold timing?

But what does this one then? ->

I have to check my logfiles but I believe this table adds to the main timing tables for a warm up timing. I know my particular setup will have up to 45 plus degrees when warming up, then ramp down to no additional timing. Or that's what being shown in the consult gauges anyway.

This is correct. What I'm adding in extra smarts for highlighting for inside the s/w which is not finished quite yet

Anyway the ECU will take the crank temp and use it to determine when to use these tables. Lots of the ECU code is conditional. ie If you re-crank again later the table may change (just to confuse things)

Cold table is used below temp and other table used above temp. Those tables are temp and RPM based and accessed in the same code routines

OK ... firstly thanks for the information ..

Right now I'm scratching my head since I did not have my morning coffee to get the brain working :)

The table name says 'subtract' ... but it does actually add?
:?:

I was talking about the advance table. I have the subtract table zero'd out.

So the base timing for idle is delivered by the Main Table?
Or is it delivered by the Warm-up Timing Table?

The idle/decel table is the main idle timing map.
