Ok - so here's the latest... I decided to hook up my old KT controller, to see if there was a similar connector explosion, and it hooked up just fine. This would indicate that my batteries were not the issue, and that the baserunner was again at the root of my problems... To get a second...

When did you buy your baserunner?

Per my conversation with their office staff when I was up there - they have been hit by supply chain issues, and don't have enough workers to do all the work currently on their plate. So its understandable, but I feel like they are their own worse enemy in choosing how to address tech issues -...

You might have missed my last post. The new controller might be fried. I don't really know what's wrong right now, but I cannot hook my batteries to it without torching XT60 connectors. Grin's tech support has been down right awful. The only real assistance I've got is from random people in...

After getting the bike setup, wires bundled and tied, and everything buttoned up (all back in mid-May), I was unable to take the bike out for a lengthy cruise / test run until this past weekend. The weather in Seattle has been garbage this spring, and finally summer struck (literally...

After I got the replacement baserunner controller, I installed it on the bike, plugged everything in, fired up the phaserunner suite, input the known parameters, and ran the autotune. This time around, it auto tuned perfectly on the first try (further proof the previous controller was junk from...

Update (sorry this took so long) - Per my last post, the baserunner was giving me a fault code, which ended up being a bad mosfet. I spoke with Grin (via email) on the fault code, and they confirmed that it was a blown mosfet. They suspected the cause may have been my motor cable build...

Did you get your baserunner setup and your bike up and running? I've got updates on mine, I'll try to post today.

Today's update - I found some folks in various online forums (in addition to this one) who provided recommendations on parameter changes, in hopes of increasing torque on the bike. Unfortunately, before I got to try any of them, I got a fault code that I could not clear. "Faults[7]: POST...

KT was rated at 25A max. So i think its substantially less capable. I found a guy via Super73 Facebook group who's helping me fine tune some of the parameters. I'll report back any improvements.

I updated the Max Phase Current to 70A. It wouldn't let me go any higher than that. I also tried bumping up the Motor Max Power Limit to 2000W (up from 1000W prior). Both seemed to help - only slightly. Still gutless from stand still. The KT had instant torque - sometimes would almost...

I spent some time this weekend messing around with various settings. Bumping up the current regulator bandwidth slightly, from 0 to 100 rads, seemed to get rid of the screeching sound and the faults/warnings, which is nice. I have no clue what a rad is though... The settings below are...

Did you figure this out? (I'm not going to be much help, just curious) Side question - under motor limits, you input 2000W and 70A.... from where do you derive the 70A number?

So with the autotune success (kind of), I’ve input the rest of the motor, battery, and vehicle parameters as best as I understand. Pretty much everything on the right though - I have no clue (Feedback Bandwidth Tuning, Output Torque Ramping, Virtual Electronic Freewheeling, and Top Speed...

To run the Phaserunner suite autotune procedure, the instruction manual says you need two parameters - 1) The kV (rpm/V) - This just needs to be close, and per grintech, most motors are between 7-12 rpm/V. 2) The pole pairs - This needs to be exact. And, per my previous post, I’ve determined...
