From what I understand when using Biodiesel in your engine you have to retard the timing 2-3 degrees. Why? Can you overcome this by using a hotter ignition system?

I can't answer about the timing, but last I knew, there was no ignition in a diesel, only glow plugs or preheaters, which only are used for cold starts. Compression creates heat, and the heat is what ignites the fuel, so there is no adjustment that can be made to control when the ignition would happen, only when the fuel is injected...

The only reason to retard IP timing is to lower NOX emissions. Biodiesel is an oxygenated fuel with a higher cetain rating than dinodiesel, It will generaly raise cyl temp by 50-100 deg , raising NOX emissions. By retarding 2-3 deg it will lower emissions. But it isn't required. FABMANDELUX.
I didn't really notice a power improvement but, my truck seems to consistently get 2 mpg better on B20 than straight dino. Which to me would indicate a small power gain which I would assume is from more BTU's per gallon.

Actually the btu value is slightly LOWER than dinodiesel, but it is an oxygenated fuel, And has a higher CETANE RATING than dinodiesel. If it is made with hydrogenated oil it has hydrogen added, which makes the cetane rating even higher.FABMANDELUX.
