Probably nothing. The procedure says nothing about flashing the ECM, only clearing DTC's and and resetting the SCR system which probably clears calibrations for the SCR cat.
Might be worth a shout to GDE just to make sure.
P.S., If they have a newer flash for the ECM available, they may do it while WiTech is connected which will overwrite the GDE tune. To be on the safe side, make a note to not flash the ECM when you bring it in.
