Hi Dennis, the most recent recent software is available on the GM Website, just below the USB interface cables in the "Motor Controller" section.
Here is a direct link to the
programming software which is compressed into a RAR file.
If you don't have WinRAR installed on your computer, check out
this post for more information regarding installation problems with the software.
I have attached a step by step guide to installing the program in such a way that it will work reasonably well, simply by making the Data.mxf file read only. If this is not done, it instantly becomes unusable when the RPM setting has been changed and then saved, which prevents the program from opening up again when you subsequently try to run it.
I have also attached a zip file containing three data files that I have manually modified with a binary editor in an attempt to try and get more than 25 Amps continuous, as well as allowing Peak Amp values of 55, 60 and 65 Amps to be set. I did this because the software does not allow Peak values of more than 50 Amps max to be entered.
I also found that loading the factory default values is the simplest way to return to a peak value of 70 Amps if you have used the software to lower it.
Unfortunately, this new controller seems to be pretty much like the other Pie controllers, as the Amp values entered in the software are considerably different to the actual current being drawn by the motor.
I've just been bench testing my motor on a 25.9V 10Ah LiPo pack and managed to record a maximum of 25.13 Amps @ 27.2 Volts = 683.7 Watts. Although this is almost a 24% increase over my original Pie, I feel it's still a bit on the low side considering the Peak setting in the software is now up to 70 Amps.
I know it's not being restricted by my battery pack as this pack regularly puts out up nearly 60Amps, and the LiPo cells I'm using are actually rated 20-30C, which is 200 Amps continuous and 300 Amps bursts with my 7S2P configuration.
Before I carried out the shunt modification on my original MkI Pie, I recorded a maximum of 20.29 Amps @ 25.8 Volts = 525 Watts, but afterwards, the maximum increased to 59.73 Amps @ 27.29 Volts = 1630 Watts using the same battery pack.
My highest recorded measurement to date stands at 60.35 Amps @ 51.5V = 3108.2 Watts, and this was powered by the same LiPo cells, which were reconfigured into a 14S1P 51.8V 5Ah pack.
I am glad my next controller will have the USB cable built into it.
Since you've apparently received it, can you please clarify whether the USB lead is actually built into the new controller like you were expecting? because I'm pretty sure you will have received a separate plug in programming lead as shown here, which has simply been shipped together with the controller:
