The Ultimate Fardriver Controller Guide (Registering | Auto Learn | Settings)

[@KingRedFoxtv]

great video! really helped me out understand my controller, thank you

[@AlexEscooter]

Great video, first video I found that clearly explained all the needed tunes!

[@AlexEscooter]

I was able to tune my Eahora M1P Pro to get 5-10mph more top speed!

[@WyomingRider]

Great Job Matt! Thanks for making this!

[@SanchoRAMZAM]

Thank you for the very descriptive video

[@Karburized]

Temp sensor; you can also set it to CACU. This allows the controller to calculate the motor temp based on reading. Cant vouch how accurate it is but it's one barrier of protection. Throttle Dec Step: you want at max 224 for safety reasons. Setting it to 224 removes the time delay from when you cut throttle.

[@FardriverTunes]

4-CACU doesnt read motor temp it bases temp readings off of the controller MOSFET Temp.

[@imho7250]

@@FardriverTunesthe original comment was edited so I don’t know if he was wrong the first time. Lol Yes, the CACU motor temperature simulation does use the controller mosfet temperature as a reference point, at least as starting temperature. The RatedPower setting is how to calibrate the thermal mass in the simulation. I made a video a year ago demonstrating it. Setting motor rated power to a lower value, decreases the thermal mass, so motor temperature gauge increases faster. What is NOT clear is whether it’s simply using MOSFET temperature change and multiplying it by some constant divided by RatedPower value, or if it uses amps as the variable for heat added. Since ratedPower has absolutely nothing to do with controller power output, I normally set it to about 50% of the motor’s claimed max continuous power, and it ensures the temperature indication and controller shutdown will be conservatively ahead of actual motor temperature.

[@imho7250]

Yes, for all direct drive hub motors, 224 accelerate and decelerate is correct. The 220 nonsense is just Ryan Goodyear’s signature so he can see who is using his tune. The purpose of slowing the deceleration ramp is mainly for drivetrains that have wind-up, such as a motor going to a differential and then an axle shaft out to the wheel, or something with lots of chain slop. Anyone who watches someone first learning a manual transmission and lurching the car as they get on and off the throttle can see why it needs to be dampened. Most cheap Chinese tricycles and golf carts don’t have proper dampening and will lurch like crazy. With the Fardriver you can tune it to be smooth even if you are trying to get it to buck like a bronco. Unlike some myths, neither one has to be faster than the other. It all depends on the drivetrain response to changes in throttle. But slowing it down a bit it allows the gear lash to be taken up and the axle torsion to wind up more gradually, and the parts will last much longer. But for direct drive hub motors we all want it to respond as fast as possible, and we can use ratios in speed to decrease starting torque if its too much.

[@Razorcrew_Cole]

Good video man

[@danielcoelhodeamorim9833]

Congratulations on the excellent work!! Your video helped me a lot! I would like to ask. On a nominal 72v, 60A battery and 3000w motor, what would be a safe setting for the "Maxlinecurr" and "MaxPhaseCurr" parameters?

[@unrivaled.zzz11]

For some reason every content creator who speaks about the PID Parameters says "DO NOT TOUCH THESE!!" But they're really not scary settings. the only things you definitely do not want to touch are MOE and LM everything else is good to mess around with. it just adjusts how power and torque is applied in relation to the throttle motor and controller.

[@AlexEscooter]

Can you give a quick explanation of each of the other PID settings?

[@SparkCycleworks]

As a manufacturer, I can tell you the vast majority of headaches come from people messing with PID who have zero electrical knowledge.

[@imho7250]

All Fardriver I tuned for hub motors needed LM tuned. 22 is too high, 16 was optimal. And the current control loop integral values can normally work better if decreased 1-2 sets below default. Proportional control settings have been blocked fo a long time. Before they were shown, but automatically adjust to 10x KI. Now they aren’t even showing whats going oh behind the scenes. Lol. The KO MOTO controller is a fardriver with some hardware changes, but it’s the same basic firmware. Anyone who knows fardriver will immediately recognize the PC app and see the mobile app is working with the same settings with a different GUI. Reading the KO-MOTO tuning guide does give additional insight into AN and LM.

[@joshuakuberski8002]

it does not matter the green one or black one they both require a Bluetooth dongle and green fardriver controller is aftermarket with a small heat sink ,the black controller is original from factory with a bigger heat sink .

[@notapie-ro8186]

How many volts does it take to turn on a fardriver controller?

[@markuscamenzind5510]

Will it connect off line once you are registered?

[@83RBurke]

I have a black Fardriver controller, specifically the 72270 but it does not appear to have Bluetooth? I bought the far driver dongle but the only open plug in the harness is a red 2 wire plug and the dongle is 4 wire. There is a female 4 wire plug which fits the dongle but when I plug in and turn on the bike nothing happens-no light on the dongle and no Bluetooth on the app.

[@Antony--DIY]

Αbout "pole pairs".... Question!! My scooter motors are 30 magnets.. thwt means 15 pole pairs!! So.. what number is better to select??? 16 or 30....🤔

[@500wattz]

Why do you have your max rpm set to 850 when the 4T qsmotor 205 is 820rpm? Did you set it slughtly higher because you use field weakening?

[@2facedTony]

Is there a way to get the harness by itself? (Without the controller/kit)

[@firecatbear1]

Any suggestions on if I’m either not getting a voltage reading on the app and the throttle isn’t responding when wired correctly Or If I swap the green and black wire to get voltage reading but still no throttle response?

[@masteraugmentedproduction5828]

I have a goat power bike model Hulk goat 5KW it uses a far-driver can I attach a Bluetooth dongle and not lose the factory options such as display remote start odometer?

[@ebikeengineer]

FYI the Google Play store IS the Android App Store. Who do you think makes the Android OS? ;-)

[@SparkCycleworks]

Thanks, to clarify, there is no Fardriver app still in the Google play store. The only way for android users is to download the app from Fardriver’s android app download page or another source online by direct link.

[@RetroMancer242]

I know, that was weird. LOL

[@FardriverTunes]

I am confident this guy doesn't properly show how to tune the controller. For starters Pole Pairs MUST BE SET BY THE USER , Auto learn doesn't adjust pole pairs. I also get the sense you dont even know what half these settings truly do. Please reconsider this video, its not helping the community by giving wrongful tuning information. Not hating just concerned, i have tuned many fardrivers for businesses professionally.

[@SparkCycleworks]

At 13:40 I specifically state that the pole parts must be set and use the motor manufactures parameters. I’ve built nearly 400 bikes since 2019. This video is meant to be an approachable overview for the majority of casual riders who just want to make some basic changes. It’s not intended to go into heavy detail for manufacturers

[@FardriverTunes]

​@@SparkCycleworks most qs mid drives are 5 pole pairs Hubs are 16 23 or 28 No hubs are 8 pole pairs ...

[@FardriverTunes]

Rated Speed and max speed are 2 different values .

[@imho7250]

@@SparkCycleworks@13:58 “That Autolearn does a good job of detecting pole pairs”. No controller on the market can magically sense pole pairs. Every programable controller will ask you to enter the pole pairs value. If you don’t, it doesn’t care, it will still run perfectly fine, but the reported RPM, and speed signal will be off. I challenge you to set pole pairs to any value the Fardriver will accept this is not the correct value, run Autolearn as many times as you want, and it will NEVER change the pole pairs.

[@imho7250]

@@FardriverTunesyes, Rated speed is measured during autolearn, changing it’s value manually doesn’t change the rated speed. And you CANNOT go to the manufacturers website to find the rated rpm because they offer many winding options. And QS never said the max recommended speed was 850 rpm unless it’s some ridiculous 5T winding. Setting rated speed and max speed to the same value does show a total cluelessness about whats going on. I mean, if 850 was the real rated rpm, just leave weak response at 7:none, and let back emf be your speed limit. Unless thats too fast, in which case you would set maxspeed to less than rated speed. It is unfortunate that so far there are ZERO videos showing how to do basic setup without lots of nonsense added. Even the self-proclaimed Fardriver God is on some KZbin videos spouting total nonsense, such as claiming the Fardriver does field weakening by increasing voltage. Thats some Flat Earther stuff right there. lol

[@Supersangron]

This is great content, thank you! As an FYI, as a first-time user, I also has to put in a password (not just the email address) before hitting the “Get Verify Code” or the app would crash. Once I had information in both fields, I got the email (in the junk folder).

[@SparkCycleworks]

@@Supersangron awesome!

[@hypedad]

My fardruver showed up with the startKP set to 0. I think they had a typo when programming. I need to change it but it won’t click on those 3 KP pids. Anyone can help with getting into the controller to change that startKP number?

[@lotion_k]

when i hit verify code, the app just closes and nothing happens, any idea how to fix this?

[@BeautyBeastRC]

im having the same problem, did you fix it?

[@AdamOpheim]

FWIW This wouldn't work on mine. I had to input a password and then click the "send verify" otherwise mine crashed every time. (Don't think it matters what PW you use.).

[@rudster999]

same here. just use the previous/older fardriver version. works perfectly.

[@FloridaVolts]

What happened if I created with my phone number??

[@RetroMancer242]

Motor explodes.

[@dasppg9737]

As soon as I click “get verify code” the app disappears off the screen. I open it again and try again, same result every time.

[@2facedTony]

Enter your email AND a password

[@imho7250]

Make sure your phone doesn’t belong in a museum. I was using the fardriver app just fine on my iPhone 6 for a while, and then after an update about a year ago, when it started asking for registration, the app would crash each time. Then I got iPhone 10 (Xs Max) and it works without crashing. So if you have a super old phone, try a newer phone. I think the same applies if you have a very old Android phone.

[@dasppg9737]

@ iPhone 15 pro max. I eventually got it working

[@imho7250]

@ what was causing the app to disappear off the screen of an iPhone 15 Pro Max?

[@dasppg9737]

@ I never figured out what really got it working. I also never got the email verification. It just started working and connecting to my controllers. Has been working fine ever since
