Well it's an older post but as a crimefighter owner and user i want to add some things the original poster did not wrote.

Let me start first with saying the prostar and crime fighter are from the same manufacktuer.
The crimefighter has come in place of the prostar alarm,
the main differences between both alarms is the crime has no knock sensor annymore so the driver paging fuction is not availible.
The range of the crime is way longer
and the crimefighter has an oled display.

I upgraded from a prostar to crime fighter
one big plus point is that the old prostar remotes the normal remote
and the watchconn remote are compatible with the crime fighter you can program 3 remotes max to the crime fighter,
so i have both old remotes from the prostar in use with the crime.

lets start with the featurs the crime has.

Full color oled display with animations
proximity sensor (passive keyless entry)
user friendly pull-down menu system settings
anti carjacking (remote engine shutdown)
up to 3000 meters range
live car status report to remote
engine remote start function
resevation mode (safety feature for manuel transmission remote start)
preset engine timed start
build in turbo timer
remote trunk release
remote central locking (door lock/unlock outputs)
incar temperature sensor
valet mode
active arming/passive arming selectable
starter kill
3x auxiliary ouputs for additional sensors or window control module
flashing parking lights
car finder/remote panic
super bright led status indicator
optional
extra schock sensor
optional radar sensor
optional glass breach sensor
optional hood pinswitch
optional remotes
optional window module
optional charger

the alarm comes with a good instalation manual
and is easy to instal if you know how to use a soldering iron and how to use a multi meter you can install it your self
the wire harnases might be intimidating but it's not just connect the cables you need that's it
i sugest to buy the optional starter kill relay you need to cut some wires at the start key ignition but again not hard to do.
when instalt power the alarm up and go thru the programming modes
turn ignition on and off 7 times to add the remotes to ad the romote pres button 2 within 5 seconds add more by then also within 5 seconds by pressing button 2
for manuel transmission set transmission in nutral start engine engine will shut off by it's self and the programming is complete.
the crime fighter is verry easy to use and reliable
and the 3 extra outputs are handy for switching extra stuff on and off like in car neon, strobe flashers etc.
it really can compete with more exspensive brands.
