There was internal trouble when in May 1988 Brun unsuccessfully tried to replace Larrauri with German driver Christian Danner.

Since the team had no money for any modification it kept Larrauri in the second car to the end of the season, much to the annoyance of most of the other drivers as the Argentine had gained the unwanted reputation of being slow and hard to pass, especially when being lapped as the EuroBruns were often.

Starts didn't turn into finishes, with engine failures, clutch and gearbox problems, and even a flat battery meaning that Modena's 11th place at the Hungarian Grand Prix would be the car's best result.

At the end of the season in December the team entered an ER188 for Fabrizio Barbazza in the 1988 Formula One Indoor Trophy at the Bologna Motor show.

For the 1989 Formula One season the car was updated to ER188B specification and used a Judd CV V8 engine and Pirelli tyres.
