I just bought the usb evolution analog upgrade kit (diy kit) for my older
tsw2. Instructions on rewiring the brakes and wheel are pretty good. Comes
with 3 50ohm pots. If you have a clutch you'll need to order another pot.
Took me about an hour to complete. Calibration in xp is dead nuts, no
jitters at all. Tried it with with GTR2 and N3, very smooth. Major
difference from using the rocketfire adapter. Money well spent.
