- This should have been my Mini-ATV build video 😭 Don't worry, you'll still get a GOOD peak! 👀
Come join me to find out just how far I go to put my 3000w electrified Suzuki QuadMaster on the road properly! You'll get a tease of just how POTENT this build is right before I detail a HUGE problem. I've detailed the experience and tests to bring exposure to the issue, demonstrate to manufacturers, and (hopefully) help the community. Let's GO! 🏁

CONCLUSION = Kunray is bad kitter / seller 👿 All signs point back to their entire kit since I experience on my workbench w/ 2 kits and 2 known good power supplies. Fardriver controllers are known to be pretty reliable. The controllers included are legitimate but the programming (by Kunray) is NOT. I've worked thru dozens of solutions from communities which were very appreciated but had no affect on the inconsistent throttle. I was able to resolve the 2nd controllers "throttle hang". That was done by adjusting Function\Follow to Disabled. This further illustrates their (horrible) quality control.
RECOMMENDATION: Stay away from Kunray. They ghosted all correspondence re: warranty claim. I was a month outside of return window, but Amazon forced the return.
WHAT'S NEXT? I ordered a more basic kit from another seller to get the ATV back on the road, and my videos back on track. LMK If you have questions- Appreciate y'all!
All my Kunray motors work fine.
I think it's that specific fadriver model. I have the same issue with throttle. If I ease I to the acceleration, things works fine.
You just saved me from buying another fardriver controller to!
The throttle hangs because "follow" is on. Make sure you turn it off before you do the learning setup. Also don't let go of the throttle until the controller beeps at you when you're doing the learn. I have a feeling one of your hall sensor wires is crossed or something. I have that same type of motor and controller and it works fine.
Appreciate you! Funny- 2 kits, and the programming was wildly different despite same kit from same manufacturer. 'Follow' was the problem on second. Hall first manually adjusted, then reverted and adjusted electronically w/ BT dongle. I went thru a host of recommending setting changes in pretty controlled environment. Enough to just throw my hands up, and re-kit. I'm looking forward to an FD build of something soon!
Set the top rpm lower too!
The throttle hang is resolved. This was the bonus throttle issue I received with second controller, not to be confused w/ larger throttle issue that plagues both. Since only the second experienced this, I compared their settings. Toggling one setting resolves this and results were repeatable.
Just didn't want anyone scratching their head on that one. You can find me on Reddit for more info, but I will not publicly disclose at this juncture. I may even interrogate you 😉
Controller is simply tuned incorrectly by Kunray. Razor guys have that combination (not from Kunray) going 45+mph.
Find Ryan Goodyear for all FarDriver Tuning needs. He admins the FarDriver Tuning for Ebikes group. Kunray needs to stick to motors only.
Agree on all fronts. Ryan was not willing to help me bc he thought I was either working for Kunray or would share his tune to resolve issue. I also had little faith that he could resolve since he has a review on the product page suggesting he returned kit w problems. Nonetheless, respect his decision and no doubt he's done great things for community 💯
NEW CREATOR: Please 👍👍 to spread the word! I look forward to compiling the solution and final build video soon!
You can follow the related thread on Endless-Sphere's forum:

Awesome to see you figured it out!
What is your minimum throttle set to?? Go to your gauges and check what it says your throttle is resting at without you turning it. If it says it's at .80 then change it to .90 in your pro settings. And as for Pole pairs they can vary between 6 and 0 for your mid drive motor I believe. Phase offset is very important so I'd suggest you pursue that as an avenue that could be explored if your throttle or Pole pairs wasn't the issue. Lemme know how it goes if you like or need any advice.
Thanks FPV! I had a great experience w Fardriver aside from the Kunray dilemma but I still had to return it since it was kitted. I put a cheap square wave kit in and ATV is amazing now. I'm a few weeks out from producing the build video. My next build will definitely use FD! Whatcha into bikes, karts?
Swap the phases and keep the hall sensors wired how they are .
Also worth exploring pole pair settings and AN settings .
Most likely issue is the motor those MY1020 motors don’t run very well with someone controllers and seem to prefer square wave units
^^ Has awesome e-Bike channel ⚡
Thank you for that, Kunray said the same thing. I was skeptic, tried as last effort before receiving the BT module. It did not run at all in that configuration.
You may be spot on re: sinewave vs. square. These were kitted together so they should come working as advertised. They have another kit w square but I had opted for the FD kit. I have some good folks from the FD group on Facebook that are going to assist me tune 🤞 I'll keep this updated and appreciate ya!
I had this same issue.. you need to go into app and disable speedlimit pin and problem solved
Thanks for watching! That option in Function had no result when disabling. It may resolve a similar issue but what makes this different is repeatable frequency. 2 out of 3 sequential throttles are fine. Only on 3rd throttle was I experiencing this. And this pattern repeats itself. Kunray is dead to me, but FD is great and plan to use again soon 🙂
That throttle hang can be incorrect due to low and high voltage cutoffs being wrong but can be other issues aswell
Thank you x3 friend- are you referring to the throttle low and throttle high voltages (1.2, 4)? I don't see another setting that touches on voltage cutoff. If I cannot resolve the throttle hang, that's OK since my first controller does not have it. I compared all the settings between the 2 controllers to see if I can find the outlier. Chart below, hope it comes out OK. It represents volatility in Kunray's programming. If a difference between settings is causing hang, it must be one of these...
PARAMETER_____________1st Controller (NO HANG)__Vs__2nd (THRTL HANG)
Functions\Follow______Disabled__________________________Enabled
Product\RelayDelay____22643____________________________22560
FixedParas\PhaseAZero_2074____________________________2084
FixedParas\Save Times: 167______________________________142
FixedParas\PhaseCZero: 2073____________________________2085
And my motor runs fine on a cheap 40 amp square wave just fine! It must be something with these motors and fardriver controllers
Agree completely, the same MY1020 is sold everywhere and I've picked up another w square wave and no more throttle issue. She rips now! More content to come on this, thanks for watching 🙂
I am doing the same thing g right now and have the same problem you’re having!
Glad ur good once swapped to square wave. So far so good w it on my end 🤞
Your pid parameters may be off.
In the video you have
An:10, 4, 8, 16,9.
Thats should be 0, 4, 8, 10, 9
^^Great Info-taining cart-centric EMV channel 🏎️
Appreciate you stopping by man! After AN (10), you must be referring to my current StartKI (4), MidKI (8), MaxKI (16) and SpeedKI(9). I was also reviewing these last night. Digesting info...
AN- I can change from Kunray's 10 to 0. Manual says 0 is for surface mount motor if you think that is right. Manual says Standard IPM motor is AN 16.
MaxKI- I can adjust from 16 to 10. I was thinking of changing to 12 since the chart in manual has that figure in configuration 4 alongisde the other KPI numbers I have.
Going to add your comments to my notes and systematically try to step thru some of these recommendations. Will keep you posted!
Go QS motor bro!
Right on, not on this mini ATV but something soon. Nice channel (subbed!) 🍻
You pole pairs need to be #3 and not 4
Great catch! This would be such a miss if Kunray is programming these as such. I will adjust and let you know. Thank you again!
No doubt you were right, but didn't fix issue. All my testing and research points back to Kunray. They SUCK- especially since they ignored any warranty request. I had to have Amz force return, and will be getting a more basic 3000w kit from another seller. I'll be back in fardriver land when I build my cart- no more kits for this guy! Appreciate you man 💪
