771xv into a 96 crown vic

I am having problems with the tach learning for this.I programed the alarm to learn tach when the car is cold ( high RPM's) this is the only time the remote start will work right when the car is started cold like for the first time in the morning..If the car is hot (driving around) and I remote start it it will die out after about 5 mins and gives me a 2 blink saying that over Rev protection cut out.If I try to reprogram the unit to lean the cars tach when the car is hot the RS will grind the starter for a very long time after the engine is running.

If anything it shouldn't be saying over rev it should be under rev.............

Any ideas at all on what to do? I would just like to be able to disable the over rev protection if i could?

Thanks a lot!

Jeff- If I do that then the starter will grind .which makes no sense at all.

J Rilla - Yea I know that is very strange. but I am into that tan/green wire

Thanks again for your help

I know  I had problems on a new ford like this.. found a third acc. wire to power.. and cured everything.. this vehicle would over crank and not let me programm the bypass module because of the third acc. wire.. I think it was a RED / blk wire... Just a thought... also ran into this on a 1999 ford super duty..same thing another acc. wire
