disconnected battery
I read on here that if your battery has been disconnected for awhile you may need to do an idle re-learn process. My question is if you don't have an OEM tune and have a Diablo Predator Tune is this still necessary?

The only things that you lose with disconnecting the battery is all the weather related tuning parameters that have been learned out--The ECM basically starts from sqaure 1 and goes thru a re-learn process--It should only take about 50 mile or so for them to learn out again-Weather related things are like atmospheric pressure--altitude-outside temp or air density ---The other times it will idle badly or hunt for an idle speed is if your T-body had learned out when it was clean and now it is carboned up some and you re-set the fuel trims or did an idle relearn or disconnected the battery after it has become carboned up and originally it had learned out when it was clean--
