Its time for 3.5 or 3.6 rear gearing !!!
you can probably get a used 3.5 w/vlsd for 500 or less... that's a decent option at a much lower price point.

Search the term "carrier".
I got 3.5VLSD pumpkin for $330 from a local auto recycler.

No, haven't tried it yet. Won't be able to for a couple of weeks, I don't have my car right now.
I'll do what I can with the shop once I get it back. I can't switch to a 6MT ECU because the 6MT ECU for my year is for a revup.
If I bought an older ECU it won't work properly because I have wideband o2 sensors and older years require narrowband sensors, from what I understand anyway.

I asked him about this:
Uprev is in the process of developing both a module that plugs into the OBDII port to let you switch between maps, as well as an ap for phones that will let you change maps remotely, possibly tying it into the alarm so it automatically switches to the theft map when you arm the alarm, but as of now base owners are SOL.

he confirmed this to be true - but speculates 6 months (or more) out... he works closely with UpRev (and was just out there last week, they were at his place the week before) so I value his info and trust it to be true.
So in your case I guess the only option for now is cheap laptop or netbook and load different flashes as needed... until the tricks UpRev is working on come out.

The short version. There are two different points from which the car calculates MPH, the wheel speed sensors on the differential and sensor on the driveshaft. The ECU compares the values, though we believe the true calculation comes from the wheel speed sensors because when you add gears, there's no speedometer error. If you change the gears, the sensor value on the driveshaft doesn't match up with that of the wheel sensors. If the difference becomes too great, the CC thinks there's a problem therefore it won't engage. The 3.69 gears cause this problem, at least in the 03/04 cars.
^No, there isn't.
The Mustang reads the VSS in the tailshaft for both the speedometer and cruise.
The G uses the wheel speed sensors for the speedometer, and both the WSS and VSS for the cruise.

oh ok, i appreciate you explaining that.....
I know this is an old thread but I thought I'd update..
Just got my car back and JWT flashed my ECU using their own software to a 2004 6MT 350Z ECU to tune the car and my CC now works. Glad it wasn't a big issue!
