The 24-year-old international striker scored from close range after 73 minutes for the 'Glamour Boys' at overcast Rufaro Stadium while Jean-Paul Mangoua Kesse was on target for the 'Mimosas' 10 minutes before half-time.
Fanatical Dynamos supporter Portia Sadomba died on Friday and her brother was a doubtful starter for the opening fixture in Group A which includes two five-time champions in Al-Ahly and Zamalek from Egypt.
"Whether to play was a very difficult decision for me and my family. I opted to start because I know how much this fixture meant to my sister and my country," explained Sadomba.
Despite shock home and away victories over defending champions Etoile Sahel of Tunisia in the final qualifying round two months ago, Dynamos are outsiders in their first mini-league appearance for nine years.
A dream start
Roared on by a capacity 40,000 crowd in the Zimbabwe capital, Dynamos made a dream start in a rematch of the 1998 final won by ASEC as unmarked Sadomba stretched his right foot to steer a cross wide of goalkeeper Vincent Angban.
Defensively fragile ASEC were lucky not to fall further behind when Sadomba headed a free kick against a post and the rebound somehow eluded three unmarked Zimbabweans.
Nimble ASEC threatened going forward and Mangoua Kesse punished slack marking to equalise with a fierce shot that flew across goalkeeper Zondai Nyaungwa into the far corner.
Angban needed treatment twice during the second half for a shoulder injury before Sadomba once again evaded his marker to poke the ball over the line as Angban dived the wrong way.
Rising Ivorian star Antoine Ngossan gave Dynamos a late scare with a run that took him past several opponents before unleashing a rising shot that was not far off target.
ASEC host Ahly in Abidjan and Dynamos face Zamalek in Cairo at the beginning of next month.
