Getting Started

If you're using the windows binary, double click the vzclustermod-xxxbeta.exe, which should open a command window like so:

Since the program is all command line, the rest of the getting started will be text rather than screenshots.

To find out what COM ports are available, type listports Example:

[incar-cluster]$ listports
COM1
COM5
COM4

A word on drivers:
If windows doesn't automatically detect your cable, you may need to go here to get the drivers for your FTDI FT232 cable: ​http://www.ftdichip.com/Drivers/VCP.htm

If you're not sure which COM port is your ALDL Cable, unplug it from the computer, run listports, and plug it back in and run listports again. Whichever one disappeared and reappeared is your cable.

Now open the port:

[incar-cluster]$ open com4
serial port opened successfully
[incar-cluster-com4]#

Note that the prompt changed from [incar-cluster]$ to [incar-cluster-com4]#

Turn the key on, but leave the engine off.

Now you're ready to work! If you're in the car, no need to change modes, if you're on the bench type bench. This will keep the program from listening for vehicle heartbeats.

To verify your cable is working, run listen and you should see something like this repeated over and over:

[incar-cluster-com4]# listen

Press Ctrl+C to stop listening, it scrolls quite quickly.

To read table 9, run read 9. This is a stock 2004 table.

[incar-cluster-com4]# read 9

Note that the shift light is off, but the RPM values are set. 2005-2006 GTOs have the RPM values set to 9000.

I want my shiftlight on!!!1 ... Ok, now send preset shiftlight-on

Easy. Other useful presets are under the Presets documentation. For those averse to RTFM, here are some good presets:
mph-dim
drl-fulloff
custom-text=RTFM
