Unhooking battery remap delete???



  BMW E36 328i Sport
I've had my car mapped at rstuning and would phone them for advice but obv there shut on Sunday. If I unhook my battery whilst fitting a new air bag will this clear the map from the ecu?

No, the data is stored in non-volatile RAM i.e. saves the data even when the power is disconected. :cool:

No you will not lose the remap, only the learning layer. you will actually feel it better after the reconnection
