Ignition timing Prius

[kurzer]

can i set the ignition timing in my prius a little earlier for the better fuel in Europe? my scangauge shows no difference between 91 and 95. so i think, the knock sensor is allready at its maximum and a mechanical change maybe a good idea.

There are plenty of vvt piggy back controllers online, I am sure any one of those would let you adjust ignition as well as the vvt paramaters too. I dont think they use a dizzy that you can just twist to add or subtract a few degrees.

Even without a disty there should be a cam angle sensor that can be ajusted.
