    I have an aeroforce interceptor and it shows I can do a case relearn if I installed a new PCM.
    How can I do this or better whats the steps I must do for the relearn?

    thanks for your answers

    I took a picture of the instructions Intense racing sent me on how to do it when I got my PCM tuned by them. I didn't have to do a case relearn, so I can't vouch for it, but hopefully this helps you.

    Just replaced my PCM today and got lucky by just doing the first one and after step 7 it started.
    1st one:
    1. Disconnect battery
    2. Install new computer
    3. Reconnect battery
    4. Put emergency brake on to disable daytime running lights (this step is required!)
    5. Make sure all doors trunk and hood are closed leave driver window down and reach in through the window
    6. Try to start. If it doesn't start, leave the key in the on position for 10 min on 97-03 cars and 15 min for 04 and newer cars. The security light should turn off after this amount of time.
    7. Turn off ignition for 3 seconds
    8. Try and start the car. It probably won't start. Repeat step 5 two more times.
    9. If this doesn't work disconnect battery for 5 seconds and then try and start the car.

    If that doesn’t work, try this one:
    1. Disconnect battery for 10 sec.
    2. Reconnect battery
    3. Turn key to ON position
    4. Do not try to start vehicle, just quickly click to RUN position to engage security light
    5. Let vehicle sit with key ON for 35 min.
    6. Attempt to crank vehicle. Once vehicle is running, the security light may still be on
    7. If security light is still on, turn key to OFF position for 5 sec.
    8. Turn key to ON position and security light should turn off
    9. Start vehicle and enjoy new PCM

    And if that doesnt work, some have had this one work:

    1. Try to start the vehicle.
    2. Turn ignition to OFF for 10 seconds.
    3. Turn ON (NOT START) the ignition (using a black Master Pass-Key III key, not a gray Valet key).
    4. Observe the SECURITY telltale on the dashboard. After approximately ten minutes it should turn off for the first time.
    5. Turn OFF the ignition and wait for ten seconds.
    6. Turn ON (NOT START) the ignition (using a black Master Pass-Key III key, not a gray Valet key).
    7. Observe the SECURITY telltale on the dashboard. After approximately ten minutes it should turn off for the second time.
    8. Turn OFF the ignition and wait for ten seconds.
    9. Turn ON (NOT START) the ignition (using a black Master Pass-Key III key, not a gray Valet key).
    10. Observe the SECURITY telltale on the dashboard. After approximately ten minutes it should turn off for the third time.
    11. Turn OFF the ignition and wait for ten seconds.
    12. Start the vehicle.

    Notes: If your car starts at any time and stays running, you are done. If your car starts and dies, try step 9. If it dies after 2 seconds after you have done these steps, you either have a bad FP resistor or the security setting in your PCM is wrong and it will need an update. Security relearn procedure will not work with the valet key!
