RL test fails

Is the motor spinning up during the test? You can try to adjust the detection parameters. Maybe up the amps and give it a bit more dutycycle and lower the ERPM or increase it a bit.
I could not find the 160SH, only 120SH? Do you have a link or a datasheet?

Doing the RL test, the motor makes some clicking sounds and does not spin on the release version or beta version of the windows app. Same for the beta android app.
The release version of the android app spins the motor and finds RL.
Revolt no longer makes the 160-SH. They really reduced their product line and revamped many things about 2 years ago. None of that really matters since I rewound it for a higher Kv and higher copper fill.
It's new specs:
6 turns, wired WYE, 78kv
4.17mOhms per phase
.01mH per phase
The motor was running on a Nucular 24 FET FOC controller. It ought to run on a VESC too! I also have a Revolt RV-100Em with a factory 74kv wind. That does the exact same thing on the 100-250 VESC controller. It's not the motors, it's the software running the controller IMHO.

I think I had the same issue with Vesc 100/250 and the latest beta of Vesc-Tool. Try changing switching frequency to 5 or 30KHZ before you do the manual detection in FOC Tab. After that go back to the default value. Regards Oliver

You can go to Motor CFG >> FOC and adjust the detection Amps, Duty and ERPM. What VESC-Tool does is the following: It creates aspinning magnetic field ( FOC open loop) and the rotor will eventually follow.
With the Amps you adjust the magnetic force, with the ERPM the speed of that field. If the motor doesn't turn, you may need to use more Amps and maybe you need to decrease the ERPM to 1000 or 500. You can also try and use 0.3 duty cycle. Once the motor spins up, you should get detection values.

Kinda sounds like your are trying to run the detection while a fault is active. Check no faults are showing on the realtime data page.
Other thing can be if your battery voltage cutoff is too high.
I have a Revolt outrunner (RV-160-SH). The motor runs! It was on a Nucular FOC 24 fet previously and it ran fine there. I was using the release version of VESC tool for android and it runs the FOC motor tests. The Windows version will not detect the motor or run it. I run the RL test and get "Could not measure resistance and inductance" error message.
Now Im trying the beta release found here to see if that's any better and neither app for windows or android will do the RL test. They both display the "Could not measure resistance and inductance" error. What's going on here?
