I mean when turning on the bike. My CA is the DP type, and controller is 18 FET from lyen. Maybe it's best that I open the controller and check the sense wires.justin_le said:

Mostly. The customer did not specify a "cheat mode", only that assist would not be available without the minimum level of HP input. From what the customer is telling me the cheat mode would have to be very hard to get into if it existed. When I mentioned the need to calibrate the torque sensor with a force on the pedals at startup he was not happy with that because the customer could just recalibrate without pressing on the pedals and get assist just by turning the pedals over with no force applied.
shorza said:
Yes, that would be the next thing to do. The sense wires and ground should be soldered right at the shunt itself. If you have the CA ground soldered on the S+ side, then any current from accessories running of the CA's DC plug will also show up on the CA which is cool, but it means that your CA's ground potential will vary with the controller ground when there are large currents flowing. So for the CA V3 setups where the throttle interface is more important, I recommend having the CA's ground tied to the controller ground on the S- side of the shunt.

OK, consider it done. A PAS assist offset setting in N-m has now been added to the Beta20 firmware. I've made it so that you can set it positive or negative, and that way it's possible to make the assist factor kick with a decent amount of power even if you are pedaling with almost no torque, for those who have the opposite desire.

thanks heaps for the change.
this will really improve my set up. the way i like to ride, is actually pedal, and only use the motor for hill climbing.
with this new offset, i can pedal and have the motor not run, until i hit a set threshold.
perfect.
thanks again.

Some strange behavior - anyone else seeing this?
When I set the throttle control mode to "Current", current limit set to 99amps,
ThrI -> Cntrl Mode
{ [Pass-thru] | Current | Speed | Disabled }
the amps cutoff bounces back and forth between "A" and "a" on the "awsvt" diagnostics/debugging screen. This happens whether the bike is at rest or moving, zero or partial throttle, etc., and at pretty much any amp reading/output.
lollandster reported similar behavior in this post: http://endless-sphere.com/forums/viewtopic.php?f=4&t=37964&hilit=cycle+analyst+v3&start=660#p649873
It behaves this way while throttle is in [Current] control mode. When I set the CA to [Pass-thru] control mode, the "a" stops bouncing. I own two CAv3's with firmware B19 loaded - both behave exactly the same.

Hi Matty, this is exactly as it should be. With your throttle set as a current throttle mode, you are effectively dialing your current limit from 0A up to 99A (or whatever your AMax setting is). When your throttle throttle is off, you are setting the current limit right down to 0A, so any time the CA sees even a hair more than 0A it would set the current limit flag letting you know what's up. At part throttle, it is the same thing, if you are commanding say 10A, then as the current jitters above and below 10A you will see the limit flag flash accordingly.

For some reason I had missed what awsvt actually was. Please confirm that I've got it right this time:
A- Current limit (Amps)
W- Power limit (Watts)
S - Speed limit (kpm/mph)
V - Voltage limit? LVC?
T - Temperature limit
Lower case = output not limited
Upper case = output limited.

Indeed, that's exactly right. There are a few fault/limit flags that aren't thrown, such as the minimum start speed limit, and the throttle overvoltage limit, but the 5 main ones are shown as described. -Justin

1) You have to set throttle output mode to RC Pulse.
2) I bought and use the "Shunt-RC" from here: http://www.ebikes.ca/store/store_rc.php.
3) You'll have to open the CA and solder the yellow wire in the 6-pin controller JST connector to the +5v on the throttle pad shown here: http://www.ebikes.ca/store/store_CAV3.php

Using V19
I have finally hooked up the pas through throttle.
I like the fact that you can set the input and output levels to get the throttle to start the motor as you turn the throttle.
I did find that the throttle is slow to respond compared to the direct throttle, I adjusted the ramp up, but it stayed slow. I also noticed that it ramped down slow, I have yet to adjust this.
I do like to wheelie my bike, with the slow ramp it is much harder to get the wheel to lift. The ramp down I nearly went over backwards as it did not shut off immediately.
I think that part of the problem is that the CA is winding back the throttle in anticipation of the power limit, to prevent over shooting the setting.
In direct mode I had the power limit set at 1800w if you turn the throttle you get full controller power for a second (about 2500w) and then it ramps back to 1800w.
In pass through mode it is already limiting the throttle at 1600w in anticipation of the 1800w limit. I increased the power limit to 2500w as a test, but it still felt sluggish.
I did like the delayed power limit in the direct mode, it gave you the ability to turn the throttle and get a power boost to out of the way of danger, without having to have the current limiting set high enough to burn out the motor. In direct mode I got about 1 second of full power.
It would be good if you could do this in the pass through throttle mode, Just have an adjustable delay. It is like turbo lag in reverse.

Hey Cruzxia, if you have your throttle ramps both set to 999 but you still see a less than instant up and down ramp on the actual output, then it could again be related to some of the other feedback gains (ie. AGain, WGain, and IntSGain) that are limiting the output change, and finding which value is causing the delay on the output and increasing it will help. This won't be necessary in the Beta20 code, but let me know with this one if that makes a difference.

I have been testing different values for the gains.
I have now set the throttle ramps both to 999
The AGain To 50 and the WGain to 5
It has improved the response of the throttle and the bike. Watching the throttle in the display screen, the output still only goes to about 2.5v under hard acceleration, so the controller only gives about 60% power. I think in direct throttle mode it gets the full 4.2v and then ramps back down to 2.5v as the CA limit kicks in.
Note: I did put a 1K resistor on the green CA control line in anticipation of connecting the pas through throttle. As I was using it in direct mode, it would have dampened the affect of the CA when it was trying to limit the power. It defiantly still limited the power, but perhaps not as abruptly as it would without the resistor.
Is it possible to alter the firmware so that you don’t need the diode in direct connection mode? You could set the port as an input when not limiting the throttle. That way you would not need the diode and you could monitor the throttle voltage via the input. It would then be easy for me to compare the two setups, as I can just swap plugs on the throttle line. At present I have to move the green wire from TH0 to THd
I think that the motor actually ran cooler because it accelerated faster, the power was on for a shorter amount of time. Eg going from 20 – 30 kph with an inrush or say 2400w before ramping down to 1800 it takes about 2 seconds, and then power down to 400w to maintain speed.
In past through mode it limits at 1800w so the acceleration is slower, taking 4 seconds to achieve the same speed change.
Adding up the power 4200w vs 7200w for the same speed change = warmer motor.
Speed Limit Test
I have also tested the speed limiting. With the stock CA settings it was surging violently. I think it is due to the high torque motor in a light bike. This bike dose accelerate fast.
I revised the IntSGain down to 40 and the DSGain down to 50 and it smoothed out the surging. I did note that it takes a while for the speed limit to kick in. E.g I set it at 19kph for the test, when I accelerate it over shoots to 36kph and then shuts off the throttle until it drops to about 16kph, then it speeds up and settles around 18.9kph.

Hi everyone, i have a question about throttle settings. I connected my new v3 ca today and when i pulled the throttle my wheel spun very slowly, i have a std chinese hall sensor throttle can anybody specify what the throttle settings should be.

Hi Brettster,
Start reading the thread. Telektek did a very very nice writeup here how to connect everything and what everything does. Also, with the very limited information that you provide, it can be pretty much anything from battery problems to wrong rdshunt. This CA is so advanced, you better start reading now.

Unofficial Setup Notes are in this post. These are temporary 'best effort' notes for very basic installation until Justin can get the Grin site fleshed out.

Hi everyone, I am running windows vista, when I plugged in the cable that came with the CA, windows said drivers failed to install, anyone know where I can get some software drivers to enable the com ports on the garage computer.
Any help would be much appreciated.

Justin provides firmware update instructions as well as a link to the programming cable manufacturer on the Grin Tech V3 page. The cable and the USB-TTL converter chips it uses are manufactured by FTDI. Please see the FTDI download site for VCP (Virtual COM Port) drivers for various OSes.Brettster said:
The FTDI OS Support page calls out Windows Vista as a supported OS. It also mentions an FTDI document, AN_107 Advanced Driver Options, however, for this application the FTDI Windows drivers will work as installed without any manual or advanced configuration.

I cannot not find that in that thread.
It is about speedometer.
As we know CA can measure speed.
But I see a problem with CA when it comes to odometer function.
"TotKm" or "TotMi" if you are in USA are registered in Lifecycle Statistic screen #7.
The problem is that you cannot enter any number of kilometers/miles into "totkm" or "totmi" ,
km and miles are counted ONLY from zero when CA is installed.
Even in tiny, cheap cycle computers you can enter any number of miles into odometer,
you can enter actual millage of your ebike at the time of installation of new cycle computer.
When I buy CA for used ebike , already with millage you would like to enter actual millage into CA.
I do not find it possible with CA.
It is kind of lacking to be able to see speed but not actual millage of vehicle.
Of course on gasoline car you don't change odometer reading but CA is totally different, it is add-on to existing ebike.
