Good guess Tek, that's what I thought, so I grabbed a spare CAV3DPS I had in Stock (with the old firmware duh!) and went to test it but obviously it needed upgrading to even work, so after doing that I plugged in and same issue?? So more confused, thinking I'd exported the bug with my, read from (old CA) and fw update and write to new CAdps, on a hunch I grabbed another grin up down (pas) double aux input switch and tested it... Lo and behold it all works, eureka! I think I've solved it. I unplug the dps and switch all inputs back to the original CA and with the new up/down switch, the 3speed and PAS all work... I'm happy, so I closed up the bike panels... I tested it on the stand and... no throttle...PHUUUUUUCK... open up panels again! switch units...working throttle, vica versa and now the throttle works! Yay, I'm done... I close up...test it and again 2 mins later I get no throttle signalteklektik said:Hey ABINY-ABritInNY said:I updated my CAv3 firmware

what the heck could be up with my CA?
I'm guessing that you have run into a bug in the 3.1 firmware that is addressed in the coming 3.11 release. My advice would be to roll back the firmware to a pre-3.1 release and then upgrade with 3.11 (next week?). PM me if you want to try an interim firmware solution instead.
Not sure why you say 1 magnet is 'slow'... reset #poles =1 and all should be fine.ABritInNY said:But one magnet is way too slow plus low speed tracking would be awful but it's all I have, so now I've been advised to hack the speedo cable and attach a link from the white wire (or black,) to any of my halls, is that correct?
You're right, I shouldn't say slow it's just after being spoiled by being accustomed to 23 pole pairs reporting their pulse signal Vs 1 magnet reporting, (I guess I could fit more spoke mags to 8 equidistant spokes and have a similar response to what I'm used to and change the settings to 8.teklektik said:Not sure why you say 1 magnet is 'slow'... reset #poles =1 and all should be fine.ABritInNY said:But one magnet is way too slow plus low speed tracking would be awful but it's all I have, so now I've been advised to hack the speedo cable and attach a link from the white wire (or black,) to any of my halls, is that correct?
Otherwise, please download the [strike]Un[/strike]official Guide and refer to section "Appendix B. Add/Remove Wheel Speed Pickup Sensor". No need to hack any cables.
Magnets do not need to be equidistant. I use three - it's really just a matter of better speed sensing at really really low speed which is normally important only to those using the speed PID controller. I have to have 3 to test firmware otherwise I wouldn't bother...ABritInNY said:You're right, I shouldn't say slow it's just after being spoiled by being accustomed to 23 pole pairs reporting their pulse signal Vs 1 magnet reporting, (I guess I could fit more spoke mags to 8 equidistant spokes and have a similar response to what I'm used to and change the settings to 8.
Since you didn't say what you are running, it's hard to tell the implications of upgrading - except to note that 3.1b22 is old - there is a 3.1 release out now and a 3.11 beta release in imminent. I would wait a few days for 3.11b2 (b1 got rejected at the last minute...). Only certain old versions can be upgraded directly using the new Setup Utility. You can try and if SU1.54 has a hissy fit, your best bet will be to just rebuild your config from scratch.ABritInNY said:I also want to know, of I should upgrade to the latest firmware version as I'm running the original update that enabled the split functionality, I did a clean template copy for that, do I need to do anything different to upgrade to b22? Is it? Or can I just updated and use the new slick looking uploader program?
There never was one.amberwolf said:Do you happen to remember which beta version had the option to start from torque alone, without cadence input?
vmbray said:...have you guys thought about having a sort of log step mode for the digital aux?
For the case of a pot on the AuxA input, you could replace the present linear pot with an ordinary 5K audio log taper pot. Done.kevinscargobike said:I’d want a log scale option for the aux pot too.
Actually, I often use the learning feature that lets you say "Alexa - play something I'd like."vmbray said:Actually just go ahead and do Alexa integration so the rider can say “moah powah!”
teklektik said:Since the CA assumes a baseline 50rpm as soon as it detects any pedaling at all, this operation will not be dissimilar from a pure torque-based getaway and never exceeding 50 rpm cadence.
The core question here is whether it simply does not communicate or gives some other error?Raphael303 said:I have tried to update my CA3 v3.0x with 1.54

Yes - exclusively for torque. The Basic Power setting applies the rpm scaling only on rpms above 50rpm (e.g. at 40rpm there is to rpm component while at 60 rpm there is 10rpm scaling.kevinscargobike said:Is there a similar minimum assumed for torque?
kevinscargobike said:I regularly find that the motor spins up when I'm just swapping which pedal is down for a turn, or when I'm preparing to come to a stop, even when I turn the pedals so slowly and gently that the freewheel doesn't engage.
I think it's more pronounced when I've used a lot of power recently (maybe some kind of smoothing / averaging?). As an example, I crest the top of my hill, and I've probably been using the (power) throttle, and I'm just changing which foot is down so that I can stop at my mailbox, and the bike jumps as if I'd stomped on the pedals, even though the assist multiplier is low, the pedal RPM was low, and almost no torque was applied.

You need to email Grin directly about this issue so the Setup Utility folks can get on board with your issue. The Mac-iness of this may at the root of the problem...
Looks to me like you may have a permissions problem and things are hanging because the temp file is never created or loaded with download data.Raphael303 said:I get the following messages then nothing, (and Grin has not responded to this yet
