Re: Tsdz2 firmware open source adapted to vlcd5

In addition to this soft start is the startup boost power with boost time and boost fade. Do you guys know when and how the boost kicks in at the start and how it is related to the soft start? i thinck it s relative to the "K soft start factor", anyway i changed "motor power boost " defaut paramete...

Re: Tsdz2 firmware open source adapted to vlcd5

Is the max power available derived from the Max Battery Power (Watts) value or the Max Battery Current Source (Amps) value or is it a combination of both ?

max power is from ; max battery current source ( amp )

Re: Tsdz2 firmware open source adapted to vlcd5

i use :
soft start 3
K soft start 0.350

PWN duty cycle up 1.1
PWN duty cycle down 1.1

it's not perfect but better than default set up, haven't any time to test more this time .

Re: TSDZ2 mid drive -- Flexible OpenSource firmware for TongSheng TSDZ2 mid drive motor

Yes, in standard mode motor max rpm is 90 but at about 75/80 rpm power begin to decrease . with a 36v motor it's easy to get power over 100rpm . As power mode is torque*cadence based, when cadence rich max rpm, resulted power begin to fall, listen, when you'r pedaling at hight rpm you can't do max t...

Re: Tsdz2 firmware open source adapted to vlcd5

what about "experimental high cadence mode"? What does it do? Increase RPM ?

Yes worked fine with 36V ( hitting easily 110 rpm ) , don t work for my 48V motor .

Re: Tsdz2 firmware open source adapted to vlcd5

Motor safer for long is 10A ... no one use this parameter . If you need to get max power for a short time let 18A max and 700W max ... all other default parameter will work fine for your use . 5. How does assistance without pedal rotation work? Is it similar to throttle or walk mode? this mean as so...

Re: Tsdz2 firmware open source adapted to vlcd5

Wow! So there no assist level for emtb mode?! It is like valuable depends on your pedaling power. yes but you can customize the eMTB mode ( by changing some values ....) So maybe this is a reason why i didnt have difference between 2nd and 3rd level on the display. I thought it will increase motor ...

Re: Tsdz2 firmware open source adapted to vlcd5

i was wrong when i used " boost mode ", in fact the right name is " turbo mode " . so you have eco/tour/speed ( or eMTB if activated )/turbo ( not boost ) boost is a feature eMTB is torque based only all mode are "power mode " based, witch mean combinaison of cadence and torque . the % don't affect ...

Re: Tsdz2 firmware open source adapted to vlcd5

power mode mean cadence*torque = X 500% mean : 500% of X . the bigger is %, the easier to get max power from motor . max power is 18A*voltage . boost mode for me is 220% and it's suffisant ( for me ) max power i'm using is 550W, max ampere i'm using with 10S battery is 15A that's my set up . here wi...

Will settings the motor watts to 9999Watts cause any issues?
Dont thinck soo, but there is no need .
14s fully charged is 58.8v, 18A is the max controleur, soo 58*18=1044 will be about the max power .

Re: Tsdz2 firmware open source adapted to vlcd5

When street mode enabled ( and activated ) it limit motor power to default 250W and speed to default 25km/h . Boost mode can't be desactivated ...you choose " when cadence=0 or speed=0 " only, you can disable boost power limit or modifie it in concerned " motor power boost " . eMTb default, mean you...

Re: TSDZ2 mid drive -- Flexible OpenSource firmware for TongSheng TSDZ2 mid drive motor

Also, I tried eMTB with sensitivity 5 and got max assist of around 350W which was a bit low for some climbs (if I went down to max assist it boosted to 800W+) Will try sensitivity 7 next to see if it will improve. Yes, if you'r using alpha8 or more, 5 it s for performers only ;) i use 7 to match 40...

Re: TSDZ2 mid drive -- Flexible OpenSource firmware for TongSheng TSDZ2 mid drive motor

Bosch eMTB is a mixe of 2 mode in fact . standard assist are : eco/tour/speed/boost when they introduced eMTB they said : eMTB replace speed and it use tour and speed variables, but you need a bit more torque in eMTB ( about 10% more torque ) for the same rpm to get power . what mean : eco is 55% as...

Re: Tsdz2 firmware open source adapted to vlcd5

Hi, does the experimental cadence mode affect the way the motor is controlled on lower rpm than normal max? Does it only raise the assisted cadence limit, or what it does? with experimental mode ( on 36V motor ) you can reach 100 rpm eand more don t match with 48V motor ( tested with 0.19 and 0.20 ...

Re: TSDZ2 mid drive -- Flexible OpenSource firmware for TongSheng TSDZ2 mid drive motor

So when do I use eMTB mode? Well to be honest not for the above situation, ie not on the road when you come to a hill but want to keep a steady pace. Instead its for when you come to the tricky single track stuff, when you need a very quickly responding motor with full range of power. I think of it...
