Unless Prosport has added a serial data stream to their product then it is not directly supported in RR Logger. Even then we don't have any details from them about it.
They did contact me to find out if RR Logger could read their controller's 0-5VDC signal. I told them no, we need a serial (or USB) data stream.
In the meantime, you can use the Phidgets InterfaceKit to read the 0-5VDC signal from the controller and log the raw samples with RR Logger. Then in a spreadsheet program you'd have to use a calculation to convert the raw samples into actual AFR.
