Good morning, l'm at a complete loss along with the performance Company I've been working with to find an ECU ( 8R3A-12A650-SB) to match up with my paperweight sitting there . They sent it out once to flagship for repairs and it worked for 20 minutes
and flashed the same code AGAIN.

if you have any inclination on where to find one and or get it repaired properly PLEASE let me know at your earliest convenience.. thank you in advance for any resolution to this Matter.
