I also added a zerc fitting and filled my cases with thermal di electric grease. It transfers heat very well imho.
How much time do you have with this approach? I'd be interested to see the details of exactly what you did, if you are willing to share.

Re: TSDZ2 mid drive and 850C and SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

Second, read the wiki and you will see you are doing the wrong compariton of human power vs motor power. Thanks for the comment, but it leaves me confused. I have been reading the wiki for a while now, but do not recall any specific discussion comparing human power to motor power. But, are the read...

Re: TSDZ2 mid drive and 850C and SW102 displays only -- Flexible OpenSource firmware (Casainho code only)

Ok, so if assist level is set too high you get less assist. I've set highest assist level to 0.9 and couldn't get more than 450-500W up a steep hill. Reduced to 0.200 motor is assisting now with 650W max, still not 750W I was getting with 0.19 firmware. Another really strange thing is that if I rea...

Neat! If I were doing it again, I'd try that, as I had a time with soldering in the tight space. Really appreciate that subsequent updates can be done via Bluetooth.
