    I am pretty sure disconnecting the battery won't affect remaps as it replaces your stock map

    Not 100% but someone on here will definitely say

    i might make a t*t of myself on this but i would think your map is held in a chip on the ecu and is not dependent on the battery to hold it,guess its simular to e-proms on control boards.

    As above said the ECU is an EPROM type unit allowing it to be erased and reprogrammed EPROM's are not volatile memory so anything written on their regardless of loss of power supply stays on their until erased or reprogrammed
