The V has a different pinout:

Where at the VI pins 32 and 34 are used for AC fan low and high speed, at the V pin 20 is used for fan high speed so its a different setup and might be controlled differently in the ROM (controlling different pin).
You might need to swap wires or send me your rom and I will copy your tables over to a 6 GSR ROM. Do you have an openport 2.0 cable?
