Awesome! Have you used any of the onboard data logging features?

No, not yet.
I am waiting on new manual update from Emsiso which should describe how to log data ... hopefully!

Tested again this morning...
Same result as before (428A).
Got spinning wheel several times but I think cause of the underground...
Controller and motor temp was absolutely ok!
The power itself during acceleration was great but I had one problem. When I started and turn the throttle switch immediately, let’s say, from zero to one (full power) the controller switched off.
But when I gave him a little bit more time, let’s say, turn the first 10% a little bit slower and get then to full speed, then it’s not a problem...
So I will go in contact with Emsiso ... to be continued...

Why is it limited to 428amps on an 800amp controller?? Is it a pack power limitation? That bike and tire wants all the torque you can throw at it right away when you set the tire pressure right for the carcass to load and deform and running sliding at 15-20% slip ratio for as long as you have power to hold it.

That bike and tire (at pressure) wants you to drop a house of torque onto it all at once and all the way down the track, ideally front wheel unloaded completely for the whole run. I promise you don't have the magnetics to be over-loading that tire and chassis geometry at launch or any speed. Just feed it everything you can creep the tune into feeding it, and give the bike plenty of time between runs after to cool when you begin to enter core saturation for the duration of the quarter mile.

Drag racing is most drastically effected by what happens in the first 60ft of the track, and 330ft matters a little, but from there if you just let off throttle and coast or continue full throttle it makes a surprisingly small difference in ET (with a huge difference in trap speed).

So I do not really know why it switched off!
And maybe I made mistake by measuring. The phase cable was not in the middle of the circle and the current meter can also measuring inrush current ... to be continued.

He switched off by over current!
Controller gain to high?
Does it have something to do with the PI regulation of torque mode?

It is normal controller tuning experience to spend at least days if not weeks of adjusting PID tuning loops in controllers before you can achieve full power from them.

It seems that I solved now, together with Emsiso, the problem. But I think my batteries are empty now!
It was a parameter setting which was not described in the manual I have. So they forwarded it today and it has something to do with my Hall feedback sensor and the settings inside the controller called „Velocity encoder factor Divisor“ which has a default setting of 4096 and is used for all other sensor types on the market which assist by Emsiso controller, except hall sensor :-(.
Had to change it to 96 (pole pairs x 6= 16x6)
And now also the sound out of the motor is much quieter!
So hope to make a next test run on airport by next Tuesday!

Woot!!

Its going to accelerate so much harder now with the full 800amps!

I will see it!
On dusty ground I direct got spinning wheel!
On dry ground not. But as I said, it feel like the batteries were near to empty!
Running them since Sunday morning without charging.
I also thinking about the cycle analyst high current version to see how many amps dc were running through the cable incl. Data analogger to get more information out of the system.
BTW: Emsiso told me that my measurement device will not show the 800A because a certain speed/frequency is necessary and I also saw the amps running down after one minute from 428A to 413A. So it will not hold the value.
Therefore I have to check the recording function of Emsiso controller!
