I have noticed on other forums that when doing mods on the MPS's that if the battery is disconnected the computer has to re learn the fuel trims etc.. when it is re installed.This results in a reduction of power etc for a few days/K's.
What i want to know is that if i hook up a smaller 12v rechargeable battery before disconnecting will this prevent it? Similar to when you use a 9v battery to prvent loosing memory power to the stereo...(what we used to do at a dealer workshop i used to work at)
I dont really wanna wait a few days after doin a mod before i can see/feel any differences.
