i’ve tired to setup the flux weaking and it seems to make no difference in speed, i’m only doing 49 when the battery is rated for 18kw. thank you in advance. i’ve attached my settings below.

The fardrivers enters flux weakening automatically, I have not found a option to turn it completly off

raisse the limit speed from 1000 to 1400
and raise the % at 1166 to 33%

and show us the rest of the settings

i’m not trying to turn it off, i just want more speed :). i’ll try those settings soon. what other settings do you wanna see
 
At keast battery current and phase current settings on the first page.

I know that you do not want to turn the flux weakening off, but it would be nice to see how much the flux weakening can raise the top speed.
My scooter was 103kph with Sabvoton SVMC72150 without fw activated, now with the fardriver I have to limit to 115kph to not risk to overheat the motor to fast. 120-125kph seems to be possible now with enough fw.

it also seems like whenever i change a setting it reverts back to how it was
 
Did you save after changing settings?
Or the setting is over the max allowed value. But in the ratios of gear there is up to 100% at ecery rpm possible.

Current settings and Max rpm should be ok

i set a few to 100, and then just turn my phone off, when i go to check the settings an hour later after riding it, the settings are back to stock. i don’t see a save button on my app anywhere.
 
It is on the first side (paras) down and left

Sorry, I only have and know the Android version.
Last time I used the IOS App was two years ago, because I could not upload a new Firmware to my ND96850 which had the upper voltage limit set to 90V, it took three month a lot of emails and two online sessions with Siaecosys but it was not possible to upload the Firmware with the old Android App.

i found how to fix it in the fb fardriver group, can you show me your settings on your fardriver? similar motor? now with a little of my own tuning i’m seeing 65 at 150 line amps 450 phase
 
I have a QS60V5000W 260 40h motor with uprated phasewires to 16mm² with 205°C , my scooter weights 183kg without me.

You have set the ratios in speed to higher values.
I would also check the value weak response

From another thread

......But doing no load tests its very clear WeakResponse7 is essentially FW:none, because it will not run away even with no rpm or current limits. But as soon as you choose anything from 0-6 unloaded it will go fast and seemingly no limit.

On the road i tested WeakResponse 7 (my normal mode) and i can reach that with about 40a DC and 45a phase, and when i set weakresponse 6, with current limit 100a DC and 200a phase, my DC amp seemed to level off at 80a and phase at about 90a and the rpm was about 10% faster.

The ratios on speed are still on the same settings the controller does during the auto learn.
You have to raise them, just look at my Screenshots.
I would ad 30% to every value up to 1000rpm, and you raise your speed. Just look at my setting, on road I drive up to 1500rpm.

i have a hub motor, no matter the settings im never seeing past 760 rpm. and those field weaking settings are my own i set them but whatever way i put it my speed or acceleration doesn’t change.

I have also a hub motor. Picture Was taken last year , there was still the SVMC72150 inside.
 
And now with the "small" Fardriver
