This is a standalone ecu bracket for SpeedyEFI's ECU. This was for their 2001-2005 Miata ECU. I suggest printing it with15-20% infill. In the pictures I had fuzzy skin turned on, but I do not recommend it. This was printed in PETG with PLA support below the overhang. Turning on brim will help adhesion to the bed. I recommend self tapping screws when attaching the ECU to the bracket, but honestly the fit is good enough to not use any.
