Miata MX5 Alternator Controller for Megasquirt

Unassembled PCB kit adding alternator control back to a 99-05 Miata after an aftermarket ECU swap

Physical productone_time

This unassembled circuit board restores proper alternator control for a 1999-2005 Mazda Miata MX5 after swapping in an aftermarket standalone ECU like Megasquirt or Speeduino, which can't reliably replicate the stock ECU's alternator-control function in software. It's for MX5 tuners who need working charging-system control after an ECU swap.
