Cold Air Intake ?
After installing an aftermarket cold air intake, do you need to disconnect the battery to allow the ECM to reset and/or learn the new system? I have one on order.Thanks,

An Idle ReLearn can be accomplished either of 2 ways:
1. If immediate computer upgrade is necessary or the car runs rough you need to initiate the 5 minute, stepped procedure.
- A/C OFF, Fans OFF
- Ignition OFF
- Disconnect Battery
- Wait 5 minutes
- ReConnect Battery
- Ignition ON (Do NOT START), wait 1 min.
- START to Idle, Verify A/C & Fans OFF
- Idle to allow H2O to reach 176 degrees
- Idle at H2O at or above 176 degrees for 5 minutes
- Ignition OFF
- Wait 30 seconds
- ReStart and verify smooth idle.
ECM/PCM will contuinue to relaern at a faster rate from a correct baseline. Usually complete in 50 miles.
2. If you are willing to wait for the computer to automatically relearn itself, it will take 100 miles, sometimes 200. You should also vary your driving habits during this time. Complete in 200 miles if no other changes made.
Note: ECM/PCM continues to slowly upgrade to your driving habits continually

When I put my Halltech Stinger on I just drove it for a while to do the relearn. Then one day when I had some free time I did the other relearn. The one I did I didn't have to disconnect the battery though, I pulled one of the fuses and did similar to the above. I don't remember the exact procedure, but got the info on the forum.
