Set it to kmh and reads 25 kmh max had to gps apps one reads 26-27 the other 28-29
With these settings 
Turn MM #1 off should be closer.
Not to worried about reading on the heads up I want speed
What voltage at speed?
Around 90v of charge
I don’t know if you are the guy. Looking for someone to get data on field weakening.
Rodney would be the ideal tester, but like me, he doesn’t have a T3.
This is a shunt resistor that I tried on a T4 with no results. It was set to 5 ohms. Pretty conservative shunting a 1.6 ohm field.
It is now set to 3 ohms which should make a radical change. Shunting 1/3 of the field current.
As I have no idea of minimum field current anything can happen. For example, being set in the controller to 3 amps, only 2 amps will flow through field.
Effect of field weakening is higher rpm, less torque, and overheating motor.
Maximum current can be as high as 30amps. This is higher than my switch and leads can handle.
My idea is to connect this across the field, either at the motor or controller.
When speed is maxed out on level or downhill, flip the switch on.
It is certainly not safe by any stretch of the imagination. Not for the motor or controller or life and limb. 
Best if someone did this that was comfortable with high voltage, and risk taking.
I would love to try it as a last resort but I would like to see what is the most I can get out of this before I go with that option … on the mm should I go with all 3 on? Any options I should change
No effect on the speed. It will only correct speedometer.
Right so I’m fooling the controller and if I can’t get the motor to spin any faster the the issue here is the motor not the t3 controller am I correct ? No matter what info I give the controller the motor will spin to max rpm and that’s it.
Sort of. It’s a combination of controller output and motor input that controls speed.
I don’t know what’s going on in the T3 to limit speed. I only know what Rodney tells me. That it needs field weakening.
Yet the T4 will spin motor faster without reducing field current further.
but If I add a different motor I can go faster with out messing with the field … let’s see what we need to do to switch to t4 is that even possible
Just took it on the road 30 to 32 mph stock tires hoping to see 35 when I switch tires
Saw 33 going down a small hill
