how long do i need to leave the ecu unplugged for to reset it on my 325i touring.

ecu code is 173 if that makes any difference.

so disconnecting the battery and connectlng the the two wires together and leaving over night would be suitable?

then whast the best way to reteach the ecu after?

reason i'm asking is cos i'm putting a mild chip in the ecu...
