I have a few questions on the settings.
"PAS Ratio (0.1 Times)" I don't have PAS connected. I don't see a way to disable this option. Does this setting get ignored if none is found? or is there an optimum setting if not using PAS?
If you do not have a PAS sensor fitted, this figure will have no effect. When using pedelec, this figure effects how much power is provided by the motor in relation to the speed of the pedals. There is no optimum setting as it will depend on each riders preferred Cadence
(pedal rate).
"Main Battery Current (A)" and "Rated Phase Value (A)" Is there a more optimum /safer setting for my hubmotor /battery combo?
The settings you currently have seem OK for your battery/motor. Increasing the current setting might allow you to climb steep hills at a faster speed, but the Smart Pie is less efficient under high loads and could be more likely to overheat, but with a 12" wheel I think you are unlikely to strain it too much.
"Maximum Forward Speed (rpm)" What's the maximum RPM that this hubmotor is capable of? I noticed the program will allow me to set it to 700. Will this hubmotor actually do that? FYI, with my current settings my MAX speed is just under 24 kph (measured by GPS) on full charge. This is about 2kph higher than the Torque and Speed spreadsheet.
The maximum forward speed is ultimately controlled by the battery voltage, so your motor is unlikely to manage anywhere near 700rpm on 48V. Although you can easily reduce your maximum speed by altering the software settings, you can not increase it above the voltage limited maximum speed. If you are reaching 24km/h with a 12.5" wheel it must be spinning at nearly 400rpm, which could the most you are likely to achieve on 48V.
Is there a guide available anywhere? Is there better version of the software than I am using?
I haven't come across a user guide for the vector controller. Perhaps GM will produce a basic guide similar to the
PDF version that was supplied with the earlier software.
The latest software on the GM website for the vector controller can be found
here, but it may not be any better than what you are currently using.
BTW, I originally installed the wheel wrong and rather than modifying my torque brackets I tried to set the wheel into Reverse. I did this successfully however, the Cruise Control was disabled in Reverse and I could not see a way to enable that feature. So, I modified my brackets and flipped the wheel over correctly.
It would seem very sensible to disable the cruise function while in reverse, but as you have already said, there are times when it is desirable.
I have not yet tried using cruise in reverse, so it looks like I may have to try it out to see if it is still the same with my most recent controller.
Alan Having tested my MP4 earlier today, I can confirm that the cruise control does not work in reverse on mine either.
