Dan was helpful enough to send me his clone file (it's the controller
configuration). I compared it page-by-page and only found one
significance difference. There's a "vehicle information" section that
has end gear ratio and tire size. In mine the gear ratio was 7:09 and
tire size 589mm. On Dan's, because he's driving a propeller, it was 1
and 100mm. So I set mine to those numbers and my low-end performance
improved dramatically. It still struggles going up my driveway but now I
feel it's a gearing problem and not a limited current problem. Also, it
can now back up the driveway. No idea if that change impacts anything
else, though.
So thank you very much Dan!
My next step will be to swap out the 3.73 gears in the diff for 4.10. I
think that will give me better low-end torque without limiting my
top-end very much. As it is, right now, I'm software limiting it to
about 80mph. 70 will do me fine.

That’s what I wanna see! The problem is that I don’t know what screens would
be useful and there are many!
I wonder if I load your clone file…

Hey Rick
I have a hyper-9 on my 20' pontoon boat and it certainly delivers full
torque off the line. I am running a "boat" controller file from hyper9 and
it is their stock HV 144v controller that can with it. I'm running it also
at 160v nominal from a split chevy volt pack. I have a whole other hyper9
HV kit going in an MGA, interesting to see how it works in a car and hoping
I don't have issues as you describe.
I know the software that comes to setup the hyper9 has quite a few options
so I could try and capture some screens if needed.
Video of my 'toon's holeshot to 20mph. Full 2 seconds quicker than a 150hp
four stroke on same boat:https://youtu.be/_VqtA0Yoksw

One thing to realize is that the DC motor would happily take full power
from the controller, and give you WAY over spec torque at the low end.

Hey all. I recently reconverted my Ford Ranger. It had an ADC 9"
series motor connected to the stock transmission, Raptor controller
and 144v pack. Now it has a Hyper 9 HV and controller, and a 160v
pack. The Hyper 9 is connected to a TorqueTrends single-speed gearbox
