CA V3 Problems

[speedyebikenoob]

I finally wired up my cycle analyst v3 to my e bike today, wasn't expecting it to be straightforward but I didn't really expect to be this lost either. My main goal right now is to get the current throttle functioning, so I set my current limit at 40 amps which is the max my controller can do and switched the throttle into current mode. When I tried riding the bike it sort of worked but there was so much lag that it made it very difficult to ride. I messed with the gain settings and it improved the response but made the throttle response jerky and it felt like a traction control system or something cutting the power. Another thing I noticed when I connected the cycle analyst to my controller was that it was limiting my amps to 33. I switched the mode on the CA to pass-thru, still 33 amps and had some lag... what? Bike feels a little slower as well when I connected it so I don't think it's just reading it weird, why's it cutting my power? Any help with this would be greatly appreciated, I looked through the owners manual and there wasn't a lot of information on this.

No one have any ideas what it is?

Sure.
Grab the latest manual. Did you walk through the setup/configuration?
Test your bike with the drive wheel off the ground.
Bypass the CA to confirm your bike works well without it.
I'd suggest the 80% rule. If your controller says 40 amps, aim to limit the system to 32.
Look for "throttle ramp" type settings.
Check the troubleshooting screen on the CA as the issue happens. You will be able to see what is limiting power, throttle in/out, etc.

It is a great device, but complicated.

Grab the manual and use the appropriate thread.

Seems daunting at first but there’s a lot of assistance!

I did walk through the setup steps of the manual, I'll read through it to see if I missed anything though. I did bypass the CA and connect the throttle straight to the controller, the reading went back to 40 amps. When I connected it to the CA, it went back down to 33 amps. I checked the diagnostics screen too, nothing I could find that wasn't normal, the throttle voltage in and out is set to the correct amounts, so I really don't know what's wrong. For some reason, the delay did go away though. Still got no idea what's wrong.

Thanks,

I'll look through these

Ok I looked through a lot of stuff and something that it said on the unofficial guide was that if the throttle output is lower than the input power will be decreased. I have a magura throttle on my bike, and on the input it shows 4.99v and I have it set to output 4.2v which is the max my controller can take before it shuts off. I don't see how this would cause a power decrease but I don't want to miss anything. Thoughts? I'm using the throttle with no resistors, when I was connecting it directly to the controller, I was using a 1.5 k ohm resistor.
