A lot of the total time has to do with technique. I just started out in 2nd gear with the 400A controller since it won't even pull 400A from a stop in 1st.
Also it's quite a bit cooler today, and the car wasn't limbered up.
Didn't do a top speed run.

Now that you have the 400A controller you might want to bid on one of these.

Haha, very funny.
Let's put the new power in context: one time you don't want to hypermile/hyperwatt is when you're bringing home the take-out Chinese food. I used the ForkenSwift to get it this evening and it was still steaming hot when I got home.  |

I haven't tried carrying Chinese take-out on my EV motorcycle yet.
I will have to take a photo the next time I have the pizza-carrying rack hooked up.  |

burnout!
So to show Ivan the POWAH of the 400A controller, I just left 2 little stripes in his driveway.
OK, so it's a gravel driveway.
But the first controller wouldn't even do that. I had trouble spinning the tires in snow!

Wow, you must have some super-duper snow tires on that beast!

Well, yes. Also I suspect the 225A has different logic than the 400A. |

Well, the 400A unit has a user-settable acceleration ramp (via a pot), and a couple of other adjustments. Haven't played with them yet.
I always found the 225A acceleration ramp to be sluggish - it definitely wouldn't give you 225A immediately from a standstill (though you could get it under way). And it would bog down in thick snow at low speeds (ie come to a stop, with no amps showing on the meter).

When you mash it to the floor how low do the volts drop? Also what kind of range can you get now?
