    TSDZ2 - can I use 850C with OSF?

    Helping a friend with an older TSDZ2 motor with 850C display who wants to switch to OSF. I have the .bin file for flashing the 860C - is there a file to flash the 850C or do we need to buy an 860C? Thanks, Pete

    TSDZ2B - if you flash to OSF can you return to stock software?

    In other words, can a person go back and forth with the software if they desire? Just checking before I flash motor/display to OSF. I have been told the stock is more reliable, that is why I ask.

    TSDZ2 with OSF - voltage = 0 when turning on

    Just installed this motor and the first ride of 16 miles went great. Turned it on next day and got the display that Voltage = 0. Checked connectors, tried another battery, same thing. Could this be wiring in the controller? Thanks for your help. Peter

    TSDZ2 dies, restarts with battery off/on, then repeats

    The TSDZ2 motors on a couple of our recumbents are connected to the battery via 2 sets of Anderson connectors. There is the wire from the motor, then a 36" extension, then the wire from the cradle. You can be riding casually and everything shuts down. Turn the battery off and on and it comes...

    Can I route wires around TSDZ2 motor?

    If I can route my wires under/around my TSDZ2 I can avoid having to use extensions. Here is a picture of the setup. But I am concerned about melting the wires. Is this a valid concern? If so, how can I protect the wires from melting? Thanks, Peter

    Can the Enviolo hub be used with TSDZ2?

    I have struggled to find out how the Enviolo hub gets its power. Does it need power from the battery on a TSDZ2. Wondering if they are compatible.

    Understanding TSDZ2 OSF Assist Types

    I would like to better understand several aspects of the TSDZ2 OSF Assist Types (based on documentation available): 1. What is the difference between Power Assist and Torque Assist? From the documentation, it looks like Power Assist merely extends the assist to 120rpm instead of stopping at...

    TSDZ2 total loss of power - cannot figure it out

    Measured voltage - 52.7 on 48V battery. It had just been charged and used about 50wh - 5 miles or so. That was the second battery I tried and the same thing happened with both batteries so I suspect something else. I have examined all the cables for damage and cannot see anything that looks...

    TSDZ2 total loss of power - cannot figure it out

    All my settings for OSF look good, cannot locate a break in the line from battery to motor. Sometimes 860C goes dark and motor dies. Turn battery off then on and works for a couple miles. Then goes dark. Seems random. 2 questions: 1. Is there a possibility that it could be a controller...

    TSDZ2 total loss of power - cannot figure it out

    Motor shuts down randomly. If I turn the battery off, then on again and power up the display everything is fine for awhile then the shutdown repeats. Trip A resets each time there is a shutdown. What surprises me is that with an immediate off/on on the battery things start up fine. Could...

    TSDZ2 Newbie with lots of basic questions -

    With Eco Cycles supplying a heat sink, is there any particular reason to set max power to 450 as suggested in the V4 OSF instructions? Can you safely go higher?

    TSDZ2 OSF - battery shows 39%, voltage at 42, 52V battery

    My wife and I have identical batteries and firmware. I am getting 80 miles to a full charge. Today her display showed 39% battery remaining but the battery shut down. Looked at the voltage available and it was just 43V. And she only had 40 miles on this charge. Why would the display be so...

    I haven't made any changes to my settings using V4 OSF. Normally when I ride I use 8-9wh/mi. Today I was struggling and getting only 3-4wh/mi. What settings should I check? Thanks, Pete

    TSDZ2 Newbie with lots of basic questions -

    Most of the settings I can figure out, but there are some that are quite vague For example, there is a MAX POWER shortcut. But what does MAX POWER do? I would love to see a manual for the common man. Grampa Pete

    TSDZ2 Newbie with lots of basic questions -

    I apologize in advance for my ignorance, but I am not quite sure of how the motor maximum wattage is set. When I see an ad for a 500W TSDZ2 how is that different from a 750W TSDZ2? Is it a setting available in OSF? I guess I am really asking if any of the info is "hard wired" into the motor...

    I am embarrassed to admit that I mistakenly thought I had a problem when I really didn't. I just needed to take the trike off the workstand and ride it. Then everything worked.

    I am hoping someone here has had the MOTOR INIT issue. I am trying to install OSF on a motor/display with stock firmware. I am following the eco-ebike instructions to a "T" and I get this error no matter which version I try to flash. I expect that something I am doing is wrong but I have no...
