Yes I opened the heatshrink and connected green wire to the green on the controller but nothing else. I'm thinking I might need to configure the controller to accept a different throttle type or maybe change the output of the CA. Em3EV website says its a hall type throttle and I think the controller has been configured 3 wire pot.drew12345 said:That's the one. The connector from shunt hooks directly to CA. Did you open the cable?
delphinus said:I tried tieing the green cable from the shunt to the green pin on the empty 3 pin plug (Throttle 0-5V signal IN) and plugged the 2pin plug into old throttle so I could use the on/off switch. When turning it on I got an error on the controller:
Somehow I managed to get it to clear and the motor ran at a low RPM with 0 throttle. Opening the throttle sped it up till I got to about half throttle then it stopped. Closed throttle and it ran at low RPM by itself again.Throttle error at power-up.
Throttle signal is higher than the preset dead zone at Power On. Fault clears when throttle is released.
Any thoughts? Is it something to do with hall vs resistive throttle?
This did the trick in the end. Jim from AFTech did some testing for me and gave me the following figures which are now working great.district9prawn said:If you got this far, and have the motor spinning up faster as you open up the throttle then perhaps tweaking throttle input and output in the cycle analyst is all that remains.
Green wire from the shunt into the throttle IN on the controller (also green).On the Output CA voltage settings you need set those to mimic the stock throttle, which is :
Min= 0.73v
Max= 4.18v
Set to pass through mode also.
What did you do in the end to fix the chain dropping? It's funny looking down and watching the motor shift to the right as you throttle up.00Tj said:Over the last week I have been dropping chain's like nobody's business and this thread has just helped me ALOT! I honestly did not even think about the fact that it could be the motor torque knocking it out of alignment!? Thanks guys!
Long time no post here,
Update bike has now done 8500 miles replaced planetary gears a few times.
Other than that the motor kit is still fine, just gone to 18s and 40a and its a whole new ball game now.
It does get warm quicker but i am careful not to wot for long periods.
it now does 28.5 mph in first gear with a 48t up front and a 28t at rear.

I will also be beta testing the new AFT kit with the same motor as this with a kelly foc at 20s and 70a with the fan cooling for the motor internals.
Watch this space for more details .
Cant wait try the new AFT mods for it to see what happens at 20s and 70a.
