Learn time on the ECM?

[neat]

Whenever I disconnect the orange wire to clear codes or change chips, the car runs crappy for about the first 10 minutes. The first time I give it some part throttle boost, it hesitates, bogs, and runs poorly. The next time, it's better, and by the third time it's usually ready to go.

Is this normal? If so, what do you guys do at the track if/when you change chips? Do you drive the car around the staging lanes or something? Will the ECM cal itself if the car was left idling for 10 minutes?

That is pretty much normal. It takes a little time for the program to learn. Letting it idle won't help. That will only calibrate the low load value at idle.To learn, the load on the engine has to be varied to get the BLM table calibrated. I drive around in the pits to get the low load values close. The high load values can only be learned on the track or out on the road where you have room to get on it a little.
