While flashing a T43 calibration in, about 5 seconds in the ECM reboots - or it does the same thing it does when EFI Live reboots it - the ECM - after a reflash - the relays do their stuff and the fuel pump cycles.

Build 211 on 7.5.7. Anyone else experience this. Never happened on previous versions. Flash goes through to end ok.

Cheerz. :)

News to us :nixweiss: (well, to me anyway).
Does it happen to any year model? Paul can test this on he' 08 if needs be.

my ve is an 07, does it on my brother 06 and my dad's 08.

does it to the ecu during flash. the ecu itself doesnt reboot but all the dash cluster, aircon etc does a reset like it does at the end.

Ah ok, it's probably the modules on the Single Wire CAN bus resetting, not the High Speed bus we are flashing on.
