The West Australian will be entered in Car #54, although he will race the VF Commodore driven by incumbent Will Brown last year.
Fiore tested with EMS at Winton last week and told Speedcafe.com that he was hopeful of coming up with a deal for at least the two rounds which take place in this half of the calendar year, at Adelaide and Barbagallo, before establishing a budget for the remaining five rounds.
“I'm very excited to be joining EMS for the opening two rounds of the 2019 season!” he said.
“Ben and Rachael (Eggleston) run a very slick operation and I am really looking forward to working with them”
Team manager Rachael Eggleston added, “While Dean is new to our team, he fitted in instantly at the test day and got along with everyone really well.
“He comes into Adelaide prepared and comfortable in the car and we can't wait to see what he can do.
“He will be an asset to our team on many levels and we are really looking forward to working with him to get the EMS cars on the podium next weekend.”
Brown will move into the chassis raced by Nathan Morcom for the past two years, making for a swap of Triple Eight-built VF Commodore chassis between the #38 and #54 entries.
EMS has advised that a driver for the #88 entry previously raced by Paul Dumbrell will be announced in coming days.
It is believed that #88 is one of only two seats left unconfirmed in what is set to be a 20-car grid for the opening round, with Matt Stone Racing having not yet named a driver for one of its two VF Commodores.
