Hey guys, venturing into some unchartered territory here and could use some solid advice.... I need to replace my ECM in my 2002 100 series. I have the new ECM (used) and have techstream and have read the Toyota T-SB-0134-16 for flashign a new ECM. Has anyone actually done this before. I dont think i have a mongosse connector, i just have the USB adaptor that comes with the standard ebay kit. Has anyone had success programming/ flashing a new ECM? any help or guidance would be greatly appreciated!!!
