I plugged in my new SST shifter, followed the instruction to enter "2. USB" in the GPLshift config file and went into GPL. I selected first and it worked. So did second, third and fourth gears. But I could not get fifth or reverse.
Whatever I do, I can only get four gears - 1-2-3-4 or R-1-2-3 for example. Also, the car will continue to accelerate in neutral, but will not change gear, so this is not Auto mode.
