VHR + FD Gear Ratio upgrades - 3.9 and 4.08

Not looking good for the the Autos if you want to keep cruise control. This is a blurb from the cruise control section dealing with the ICC, I'm still looking for a section seperate from the ICC but I'm willing to bet it uses the same logic. It's from a section talking about trouble shooting and what might cause the cruise control not to work.

If the vehicle speed signal (wheel speed) from the
ABS actuator and electric unit (control unit) and
the A/T vehicle speed sensor signal (output shaft
revolution signal) from TCM, received by the ICC
sensor integrated unit with CAN communication,
are inconsistent.

I'm pretty sure it's saying that the computer takes three different inputs from the CAN bus and reads them. The computer tables are set up for the stock rear gear and after you change the gears the driveshaft speed and the rear wheel speed do not match in the tables anymore and cause it to fail safe (OFF).
