Idle Timing - Tables

Idle Timing is set by either of two tables depending what gear we are in

In Drive or In Park

So what we can gather from these tables, is that for example in Park (second table) in my case idling at 550 RPM my timing should be somewhere between (the 400 RPM column) 19° and (the 800 RPM column) 21° so obviously we can call that 20°. We are looking at the very top left hand corner of the table.

Note: These tables look very similar to the Base timing tables, ie High Octane and Low Octane ones, however note the column headings on the top, they go from 0 to only 4,800 (I guess that's high enough for idle, ha ha) but also note the break points, where is 600 RPM, where is 1,000 RPM? The point I am trying to make is that these tables do differ slightly, but it may be enough to trip you up if you try to reuse the Base timing Histograms we built earlier on, cause you get lazy or are not paying attention to detail.
