shlomi_beno so if understood right the ecu is learning the amount of airand the fuel needed and adjust so if i do a remap, what prevent from the ecu to change the map back to normal after a few miles or if i disconnect the battery and reset it thank u
shlomi_beno it flashed instead the original so if i reset the ecu the default map will be the one i install ?
miniator if you flash an eprom chip the old map is completely over-written. the only way to get the old map back is if it is reloaded onto the eprom chip
