“UPP is one of those reputable, premium ebike pack manufacturers.” I could be misreading, but it sounds like you're attributing that sentiment to me, which is not what I said, and it couldn't be further from the truth. I'm aware of the horror stories. When the topic comes up, I go out of my way...

The main problem here is that, for a lot of groups, forums, and people who claim to be experienced and are quick to give out advice, UPP is one of those reputable, premium ebike pack manufacturers. Most people researching ebikes for the first time never even find out that ES exists. UPP built...

Slight correction here - "Virtual Electronic Freewheeling" is a feature that was added to Grin's Phaserunner motor controller, but it is not a feature of the CA3. I recall some talk about adding it to the CA3 at one point, but if I recall correctly, Grin found that they get better 'freewheeling'...

It's not explicitly a list of differences, but the CA2 and CA3 each have detailed info pages on ebikes.ca https://ebikes.ca/product-info/grin-products/cycle-analyst.html https://ebikes.ca/product-info/grin-products/cycle-analyst-3.html Basically, the CA2 is much closer to being 'just an ebike...

One thing I've noticed about Grin hardware is that they don't seem to bother all that much with keeping up with the latest tech. The CA3 hardware may be divisive, but it remains competent at everything it's designed to do. So if the features it offers are the features you need and you can...

The GMAC does drag, due to the locked clutch that allows it to do regen. However, just like a DD hub, you can overcome that drag by feeding the motor a tiny amount of current while rolling, just enough to overcome that drag, which costs little enough power that regen typically remains a net...

3 of the wires will be for the turn signal (one wire for power in, one wire for power out to the left turn signal, one wire for power out to the right turn signal). 2 wires will be for the headlight button (one input, one out to the light) And 2 wires will be for the horn button (one input...

Front motor vs. rear motor makes no difference for what you're asking. You want a geared hub motor, instead of the direct drive hub motor you have now. Geared hub motors (with the exception of the Grin GMAC) have the clutch mechanism you're looking for, to allow the motor to disengage from the...

Are you using an external shunt, or are you plugging your CA3 directly in to your Phaserunner? If your CA3 is plugged in to your Phaserunner, your shunt value is still 20x too high. It needs to be set to 1 mOhm, not 20 or 40. Your CA3 is demanding 20x more power output than it thinks it is.

As HrKlev pointed out, that shunt resistance value under Calibration Settings is eliminating any possibility of correct behavior, until you fix it. That should be first priority. With the wrong shunt resistance value, the CA3 is reading incorrect wattage values, and using that bad information...

If you're using the mid-drive for braking, than that's what needs the torque arm (or rather, it just needs to be very securely installed in general). The hub doesn't need a torque arm for the same reason that you pedaling your single-speed or derailleur bicycle doesn't necessitate a rear hub...

First, check the CA Shutdown Voltage setting under Misc Settings. It'll be 'Vshutdown' if you're programming via the CA3's display. If that's set to 42v or thereabout, set it to something way lower - lower than you'd ever see in normal use. 12v or thereabout is good. The CA3 can't regulate...

I misremembered exactly how the CA3 handles the LVC. With the CA3, rather than having a rollback start voltage and a rollback end voltage (like the Phaserunner does), it instead simply has that one LVC voltage setting which you found. However, rather than the CA3's LVC being a hard cutoff like...

Basically, if your CA is going blank, that's your battery failing at that point. The CA doesn't blank out until you drop below ~12v. So, it's likely that the problem is your battery's BMS cutting you off, for whatever reason. One potential and likely reason for the BMS to cut you off is that...
