How to Read/Write ECU with GODIAG ECU GPT Boot AD and J2534 Device?

GODIAG ECU GPT Boot AD is compatible with ECU programmer such as Foxflash, Tactrix Openport 2.0, SM2 Pro, etc and GODIAG GT100/ GT100+ to read and write data using the OBD2 Bench or GTP Bench method (without disassembling ECU) or Boot method (with disassembling ECU). Here we will use SM2 Pro J2534 device to demonstrate how to operate.
