Does anyone know how much of the autotune grid should be green before flashing the ECM? I've ridden about 40 miles and 35 cells are green. Many others are yellow.

Thanks!

I think I remember reading it took a Tankful. 40 Miles isn't enough to reset a cars computer. I would be more concerned if I hit 100 and it didn't reflash. As you're not always riding in the Yellow Pod zones.

I am considering buying the FP3 but wanted to find out from those who have one if it is really worth it. Currently I have a V&H competition slip on and actually like the "backfiring" sound. Is there a negative impact on the engine if it keeps running like that? Any comments would be appreciated.
