Biodiesel ignition Q's
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 have never heard that. so far no one has had any issue with out retarding the timeing that I know of.
maybe because the way bio is made, any residual methane jacks with the timing and retarding it will counter act it.
just speculations....

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.

Depends on feedstock, approx 6 -10 percent. We had ours tested: 8.4 percent.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.

More BTU's?

Yes the biodiesel from crystalflash @ 5% soy is 51 min cetane. VS 40-42 cetane for #2. Just like adding racing fuel to your car.
