2000 excursion

[01Bundo]

Last night at a family get together my brother wanted to install his superchip into my newly purchased excursion. His truck is a 99 f250 auto and mine is a 2000 2wd auto both 7.3 psd. After uninstalling from his truck and attempting to install in my excursion it ran like crap. Theft light came on and ship points are messed up and will not go over 45 mph. So i returned to stock in my excursion and still ran the same and theft light is still on. I tried to install back in my brothers truck but the superchip programmer is saying no connection, checked connection and seems to be fine. When turning the key to wait to start(wts), the wts light does not come one and truck turns-over but will not start. Does any body know what is going on, thanks in advance for any help.

Did you save your stock tune before installing the superchips? I think you have to do that first. If not you might have to go to the dealer for a fix.

Excerpt from superchips 1705 maunal regarding excursion anti-theft:

If you have a Diesel Excursion
If you have a Diesel Excursion, there is a quicker way to reset the PATS system.
THIS ENTIRE PROCEDURE IS CRITICAL: Ensure this procedure is started with the KEY
COMPLETELY OUT OF IGNITION.
This technique will only work on a Ford Diesel Excursion
1 Ensure that the key is OUT OF THE IGNITION to begin.
2 Insert the key into the ignition.
3 Turn the ignition key ON, DO NOT START THE VEHICLE.
4 Look at the Theft light on the dash. The Theft Light will be blinking rapidly…approx 3 blinks per
second, indicating Theft.
5 After a period of 30-45 Seconds, the Theft Light will blink slowly and /or go out.
6 Now, turn the key to the OFF position and remove it from the ignition. DO NOT TRY TO START
THE VEHICLE.
7 Pause 10 seconds with the key out of ignition.
8 Insert the key into ignition.
9 Turn the key ON, but DO NOT START THE VEHICLE.
10 Look at the Theft light on the dash. The Theft Light will be blinking slowly…1 blink per second
(normal mode).
11 After the Wait to Start light goes out, the customer can then crank and start the vehicle normally.

Thanks for the replies. I just tried the theft trick and did not work, I drove it around the block and I have very little throttle responce. Please keep the suggestions coming I need to fix this.
