Only a win would have been a better result for Davison, who was left without a drive after his 23Red Racing seat disappeared mid-season nearly 12 months ago.
"I'm stoked, personally," the 38-year-old said after the race.
"It's about shifting the mind. The team's champion, we've got high expectations.
"For me, for my first race, I'll absolutely take it.
"Sat on the coach watching these guys for most of last year, which wasn't much fun.
"I was hoping I wasn't too rusty; trying to get up to speed yesterday, lots to learn with this new car.
"Just trying to adapt quickly without making mistakes."
