Omega starter crank time

I have an Omega AL-2000-E remote car starter.  I installed it on a '94 buick century.  My problem is when it's cold, the car will not start with the remote.  The unit will try three times to start the car.  Each time though it's only getting about two and a half cranks.  Unfortunately not long enough to turn it over.  It will start eventually if you keep trying it.  I know there is a process to program the omega units to allow for more crank time  but I can't seem to locate that info.  Any help is appreciated.

Thank You
