747 Idle Learn, GM OEM

[rauscher at icst.com]

     I have a good question regarding the 747 ECM. Does
     this system need to go through an idle learn?
     
     
     I ask as I know that there are other GM ECM's that
     do go through an idle learn. While in this 'learn'
     time, the idle is about worthless. The engine will
     stall, sputter, rev-up, rev-down, heck, I almost
     hit the car in front of me during one 'rev-up'.
     
     
     If the 747 has an idle learn time, it may help to
     explain why so much work needs to be done to get
     some vehicles to idle properly.
     
     
     I now know the manual procedure for the idle learn,
     it takes ~20-30 minutes at idle. Or, like I did,
     a full weeks worth of driving... This is on a '92
     MPFI 3.1L Camaro. (A 1227737 ECM??).
     
     
     
     Thanks,
