ECU relearning? So I went and installed my laser shifter while doing that the pcm and the battery were both disconnected. After all was said and done (3 hour later) I hooked everything back up... I then started the car up and the idle was really low about to kill the engine. It did this throughout a 30 min drive in the city everytime I stopped the idle would go low.. Throughout the drive it got a little better and better to the point the idle was normal while stopping.
This was the PCM relearning the fuel trims correct?
Also Will I need to retune the car. I used HP Tuners to drop the fan temps and disable cags..
Thanks

You will not need to retune the car. If you disconnect the battery and do not perform the idle relearn procedure, it will take a couple of drive cycles to complete the relearn. Sounds like it's already fine, so you should be okay.
