New infineon consistent Rshunt value?

[tron]

I have a 48v 30amp shenzen controller and read a post from knuckles that the new controllers shunt are now all a consistent at 3.8 mOHM . Does that mean I can program my CA's Rshunt value at 3.8 mOHM and voila? Is there more to it than that. I was hoping that the Rshunt value of 3.8 mOHM would at least ball park it and get me up and running but no luck
I'm not very tech savy but can use a voltmeter and a soldering iron (even built my own hall tester) yet I'm having a hard time setting up my CA with the proper Rshunt value. I have a voltmeter with 10amp unfused capability to calibrate my CA but electronics are hard to get access to where I live. I'm still considering the easiest way to conduct the calibration. rkosiorek's nicad D cell is looking good to me right now but I don't have access to a ammeter other that my voltmeters amp scale.
My motor runs without the CA plugged in but when I plug it in the motor runs at low speed then gradually shuts off then "boom" large shots of inconsistent power at WOT. I may have to look at my phase/hall connections again because mine seem to be different than Knuckes Grubee setup. There is a faint bit of "cogging" but it did this with the old controller. Is this symptom because of the bad a Rshunt value or does it sound like a bad phase/hall combination? I thought you could still run a setup with a uncalibrated CA? Help !

My CA's problem might be because Keywin wired the Hall wire to the hall sensor
amplifier and instead of direct to the hall sensor. I have a 116 controller chip and it
seem to act differently than the true Infineon boards. This could be the cause of the
weird speed readings. I'll try this and report back. :wink:

Tried my bike with the controller's CA hall wire change and voila! I finally have accurate
readings. Well, at least for the speed and voltage. I'll be fine tuning the Amps reading via the
Rshunt setting probably with the excel spreadsheet. I really like methods new 10amp foam
cutter/charger calibration setup for accuracy but I can go through the pain of doing it
manually for now (cheaper and its my first build).
