slight problem with remote start

I currently installed remote start,everything works except the remote continues to crank the starter when it has already started. the tach wire is connected to the blue wire in the distributor. I have no idea what is causing the remote to keep starting. The wires are all connected correctly according to the instructions via wiring harness in the steering column. Please help, thanks for reading any help would be appreciated.

Check to see if 1. the system is set up for tach sense and not voltage sense and 2. if the system actually learned the tach signal. What type of system is it?
