tach programming

I installed a Asianwolf 8000RS on a 2002 cavalier. I ran the tach wire from the alarm to the white wire going to the ignition coil plug. Now in my manual it talks about programming for tach/RPM mode. Here is exactly what it says....

20. Engine Sense mode. Selects between tachless and tach monitor operation.... now that means nothing to me since I have the tach wire installed.

21. RPM learn/Tach monitor. This dual program branch sets the engine mode for gas or diesel, and learns the vehicle's RPM threshold.

RPM learn/ Tach monitor. start the engine, enter branch 21 and press button 1 to learn the vehicle's tach signal and set to tach monitor mode. the siren will chirp and the LED will flash once to confirm learning of the tach signal and set to tach monitor mode. The siren will chirp four times and the LED will flash four times if the tach signal was not learned.

Tach monitor mode: monitors the vehicle's tach wire (of a fule injector's wire) in real time to determine engine status and adjust starter crank time automatically.

Now my question is that I never programmed any of that. I remote start my car and it starts up fine. Must I program it or does the remote start wait till voltage goes through the vehicle's tach wire (white wire) and thats how it knows when to dissengage?

If you didnt program either option, it will be able to crank the car and start it if the car normally starts easily.  on my car, the engine is big so Tach program is completely necessary for me.  The engine could start almost instantly or take up to a few seconds...

I would advise programming, just to be safe and prevent over crank.  program it on a cold start, start the car, do the 5 Valet button presses select the channel etc...  in my car I gave it a little gas, because the starter brings the engine up to 900 RPMs easily.  even though it may be high, it helps guarantee starts, w/out starter problems.
