Overkill PCM

Installed Overkill PCM in my 04 Grand Prix GT2. Unable to start the car. Tried doing the security relearn for 10minutes on, 5 seconds off 3 times. Nothing. I've also tried the 5 seconds on 10 seconds off for one cycle as recommended by will at Overkill. All doors, hood, trunk, were closed at the time. I reached in through the window and did the security relearn. No luck.

Also removed after market remote start unit just in case that was causing it to not relearn since the remote start has its on Key. I then did the security relearn still nothing. DIC showed Theft Deterrent warning. I emailed will again waiting for a response.

Does anyone have any ideas what the problem is?
 


Set the parking brake to disable the daytime running lights system to avoid draining the vehicles battery.
Try to start the vehicle by turning key to the START position (using a Master Pass-Key key, not a Valet key).
Observe the SECURITY telltale on the driver information center. Allow the key to fall back into the ON position. DO NOT TURN THE KEY TO THE OFF POSITION.
After no less than fifteen minutes turn OFF the ignition and wait for ten seconds.

suposidly you have to wait 15mins between each time you shut it off. idk tho ive never do it
 
15 was longer than he recommended. I did see on ZZP's website that 04+ require 15minutes. I will give it a shot. Thanks
 
Last night I installed the PCM again. I did the 15 minute cycle 3times and it worked. Car started up.

Thanks man
