Locked out timing is locked. It is fixed it does not advance with rpm. No ECU control.
You need a electronic boost ignition retard box. Not some ECU from a EFI system. Get a clue or it will be a very short ride.
Locked timing is the same at idle as at max rpm. No mechanical advance ---no ECU timing control.
Blower motors do not use the same timing curve as a N/A car. ECU from a EFI system will not work.
remove or disable.....
