The 4yr-old gelding, named for a Puerto Rican boxer, Hector Camacho, became the best New Zealand product of Royal Mattjesty with his comfortable win at Forbury Park on Saturday, earning his third career win at his 13th start.
But driver and co-trainer Terry Chmiel said on Saturday the biggest challenge was keeping one step ahead of the bay.
''He's been very disappointing the last few starts. We changed his work around a wee bit and gave him a wake-up at home, and he was a different horse today.
''We're hoping that worked but he's got a few brains. He thinks a bit more than us.''
Macho Comacho looked like a world-beater as he breezed through his first two starts as a winner in September 2012 before the wheels fell off in mid-October.
''He won his first two but then he didn't know what to do. He's had a few soreness issues, too, so hopefully, we're on top of those.
''He's got a big motor but he hasn't been delivering on race day. We're pleased to get him back on the way forward, anyway.''
Chmiel sent the gelding to the lead early and put the pedal down to pace a tidy 28.3sec over the last 400m.
A standing start is a likely option for Macho Comacho as the Leeston-based Chmiels look to keep him going over the colder months, either here or at Addington.
''With the mobile, he gets too keen, and he fights you too hard. In the stands [standing starts], he's usually a good beginner.
''He could have gone another round today, which was pleasing. He went clear and knocked off, so hopefully, things are on the up.''
The Chmiels' trip south from Canterbury was worth it, as they also prepared the Jereme's Jet filly Starlet Lavra to win her second race. Chmiel adopted similar tactics to Macho Comacho's win, taking up the lead and pacing the 2200m in 2.49. 4 to hold off Frank The Duck by two lengths.
The day finished on a high for Mosgiel trainer Martin Denton, who prepared The Roman Prince to beat a small non-winners field over 2200m.
Denton and co-owner Garry Clarke bred the 3yr-old son of Julius Caesar, who is a full brother to Julia's Song. The mare was exported to Victoria in 2010 and has won 14 times there.
Denton dedicated the win to committee member Don Cuttance, who died on Friday, after a short illness. Denton had been friends with Cuttance for many years after they worked together in the shearing industry.
Cuttance also gave Denton his first horse, Choir Boy, who won at his second start at Omakau in January 2005.
The Roman Prince was one of three winning drives for Jonny Cox, who now has 50 wins for the season for the first time. His previous best tally (40) occurred twice, in 2011-12 and as a junior reinsman in 2004-05.
