Stunlocker?

[thebarber]

My mate wants me to get his e8000 bike to 20mph.
I assume it's got the latest software so would stunlocker work without downgrading it?
Although I have the pce1 box I don't have a computer now, just tablet and not sure if it'd connect.

I'd check this one ..

New Shimano FW update E8000 - 4.9.0, E7000/E6100 - 4.6.0, E5000 - 4.4.2

Yesterday Shimano releases new updates for E8000/E7000/E6100. It looks like something was changed related to derestriction. Well, as usual: don't update FW until you are sure that it is compatible with the features you need.

So reading that he needs to revert back to fw 4.3.2 to get USA limit?

 

[Gary]

Nah. I have US limit on 4.7 bruh

 

[Zimmerframe]

I think, but I'm not 100% sure as I've not really been keeping track of it..

I think it works with upto 4.7 - but not 4.8 or 4.9 .... though part of me thought I'd seen that fixed somewhere too (but could be imagining that part and getting lost in version numbers) - I did have a beer earlier .. what day is it anyway ?

 

[thebarber]

Umday, I think but don't hold me to that..
This says 'Market setting 4.8.0, Top speed adjustment 4.3.2'
I'm assuming market setting is country which is all he needs, USA 20mph

 

[thebarber]

Nah. I have US limit on 4.7 bruh

No issues with it then fella?
I'm still on emax and no problems, great service but I paid for that so never had to look at St Un

 

[Gary]

Nah...
Switched to US region and wheel circumference altered (true circumference*0.621) to give assistance up to 32mph
By doing it this way if I still had a display switching ti to display kmh would showing true mph value.
I don't have a display though.
If using my garmin the circumference setting messes up Ebike speed metrics but I have a wireless garmin speed sensor on the hub that sorts that out

Only issue I've ever had with STunlocker is having to buy the license for each new motor every time my motor dies and is warrantied

My original Peartune from 3 years back still works BTW. But it won't work with 4.7 firmware

 

[thebarber]

Champion, Marcus at emax just se t me a new code for new motor but I suppose that's the price difference.
Cheers dudes.

Hey Gary
It'll only go down to 1300 circumference

 

[Gary]

What rear wheel and tyre size are you using like?
27.5x2.0 tyres have a circumference of 2152mm
2152x 0.621 = 1336

27.5x 2.4

 

[thebarber]

I got it now ta
I thought yo meant put 0.621 in for circumference

 

[Gary]

You've got your sums wrong somewhere then.
27.5x2.4 is around 2217
So you want 1321

Ah thought barber tryna build dis..
