I changed my piping back to stock today and wanted to get my spare ECU recalibrated for my car and they said that it wouldn't relearn the anti theft. Was the dealer doing something wrong or anyone have this issue? If there is another thread that explains this please out the link in here but I have looked and found nothing.
Thanks

 

ZZP had the relearn on their website, but I'll look here for a copy. BRB

Found it...

How do I perform a security relearn?
For the seed key relearn, this is the procedure:

You can open and close the door- It doesn't matter. You will need to get in and out since you need to push in the clutch.

1. Depress the clutch and try to start the car. If it does not turn over, let off, but leave the key in the run position. The security light should be lit up on the dash.
2. Wait 10 minutes(you can open the door and get out). The security light on the dash will turn off after 10 minutes.
3. Turn the key off for 5 seconds, then depress the clutch and try to start the car. If it does not turn over, let off, but leave the key in the run position. The security light should be lit up on the dash.
4. Wait 10 minutes(you can open the door and get out). The security light on the dash will turn off after 10 minutes.
5. Turn the key off for 5 seconds, then depress the clutch and try to start the car. If it does not turn over, let off, but leave the key in the run position. The security light should be lit up on the dash.
6. Wait 10 minutes(you can open the door and get out). The security light on the dash will turn off after 10 minutes.
7. Turn the key off for 5 seconds, then depress the clutch and try to start the car. The car should start on this attempt.

 

Thank you so much! I will try It when I get up in the morning. Hope it works

 

I used it on my LNF a few times.

 

It worked! So happy

 

Glad I could help out.
