DanGT86 said:I assume you mean .45v/sec on the throttle up speed? If so try increasing that until you get the acceleration you are after. One of my bikes is at 5v per sec. At some point that will be so fast it will feel like it used to before the CA.
I think the fast throttle up must have speed signal working to function. The idea with the fast throttle up setting is to pick a very aggressive ramp up speed but only to the amount of amps it takes for the bike to begin to pull from a roll. Its hard to guess an exact value for these amps. You can try 10v per second and see if it feel different then go up or down from there. 4 amps is probably a bit on the high side. I would guess 2amps. You will know that is too high when there is a momentary jolt when you throttle from a steady cruise state. This is the result of it overshooting a bit at the faster ramp speed. Remember the controller still thinks the throttle is speed based. So without the fast throttle up feature you would have to wait for your normal ramp speed to catch up with however fast you are going. You can try crazy high volts/sec settings for this just dont set the amps too high. If the amps are close then the overshoot will be very brief and not buck you too hard.
The AUX switch/ potentiometer cant control acceleration specifically but if you are using a watt or amp based throttle strategy then then it will have a similar effect. A 1500 watt bike wont accelerate as hard as a 3000 watt bike. So when you get time or energy to tune the throttle in watts or amps rather that simple time based ramp you can use that aux switch.
The CA allows you to have different profiles. So you can have one profile set for you and another for your son. I believe they can have completely different acceleration ramps and power settings. I have not used this feature so you need to study the manual. I have seen the profiles in the setting menu before but I only use one of them.
Most controllers default to speed #2 with the 3 position switch unplugged. Some have a simple 2 wire connection that is the highest speed. Its hard to know what you have. Most of the time the speed switches have a common wire and 2 speed wires. Wire 1 to common is speed 1. Wire 3 to common is speed 3. No wires to common is speed 2. So unplugging it is the same as 2.
3-5kw could be fun on the 125 if the trails are narrow or if its geared for a top speed of 30mph and you like trials or technical riding. A full size moto frame probably starts to get fun at 7-10kw. Thats all just opinion.
You're super helpful!! You're awesome btw, thanks a bundle!
I tried setting it to 5V per second and that flips the bike with me on it, same on 3V but I kinda like it, either way. Its not for me but my son so we settled on .5V. Dialed up the fast ramp to 5V and Amp to 2, guess a little better? Or just placebo.
Bike is pretty much dialed in now for my sons current level and its awesome, he loves it. Throttling still gives a punch or kick rather for a very brief moment and im not sure why, son doesnt like it or neither do I really, but perhaps its whats supposed to happen? Its like when you toll a car with a rope.. when the rope is not straight and you accel the second car jumps briefly, its that and son doesnt like it one bit.. but we're both novices so perhaps he gets used to it but he likes the new power alot!
Gonna try a few different profiles and see what can be done and plug in the aux pot and buttons and try something with them!
Capped the speed at 25km/h atm for testing purposes and it seems full throttle and it kinda holds the 25km/h limit but very jittery, what could be the cause of this? Or is it intended? I noticed the speed setting and you could change circumfence? The bike has 10 tires and im not sure what value to set here.. its at 2000 something at the moment - what does this setting do?
Other than above, theres just a few things left to do with the bike and perhaps you could be of assistance here too?
Im looking for a charge port to mount on the bike that needs to be somewhat weather proof and should handle 72v 5ah as that is what the charger do. Any ideas?
I used the stock one yesterday and it seemed fine but then suddenly it bursted up in sparks and fire haha! It was a 3 pin header mounted on the chassi.. the thing just melted!!
Then regarding the sparks. I have xt anti spark plug between shunt and battery now but no matter what I do it still sparks, ideas on that aswell?
I would also love to change the throttle to something more robust, sand gets into the throttle all the time when son falls off in sand. Is there some more robust electric throttles?
Best regards!
