Thanks. I should have added that the Hyper 9 has its own controller. The
Raptor is gone now.

I wonder if Damon Crockett at AllTrax, original designer— can help you.
Peter Senkowski took over the Raptors later. Damon is a great guy and has a
passion for on road. Nothing to lose…

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.
For the most part I'm very happy with everything, especially since my power
consumption has gone from about 2.7 to 3.6 miles/kWh but it feels to me like I
have a problem at the low end. In normal driving the truck accelerates like my
old '64 Beetle used to. That's okay but it's a real problem going up a hill. My
driveway is rather steep and the truck can only manage about 10mph going up the
hill. If I stop on the hill it won't move at all. Nor will it back up the
driveway.
According to the torque charts from Netgain compared to the ones from ADC, the
motor should be plenty strong. I drove almost all the time in 2nd gear which
was 2:1 and the TorqueTrends is set to 1.9:1 so there's a little penalty there.
I am thinking about changing the rear end from 3.73:1 to 4.11:1 which will help
get the gearing back.
But it feels to me like the issue is that the controller is SLOWLY ramping up
the current when I step on the accelerator. When I turn in the driveway I can
put the pedal to the floor and the battery amps don't climb above 100 until I'm
nearly at the top--about 6 seconds later. If I'm driving at 20mph and stomp on
it, the amps will zoom right up to 400 and the truck accelerates nicely.
Does anyone know of a setting in the controller that can tweak the current ramp
up speed? The current limit page shows 100% across the entire RPM range, so it
has to be somewhere else. The throttle page shows that I'm getting full pedal
travel. I'm not looking for burnouts but I'm dreading the day I have to stop on
a steep hill on a real street. Thanks for any help.
