ECU programming and reflashing tools

ECU programming tools write to the control module rather than only reading from it. That covers reflashing, cloning, adaptation after a module replacement, and J2534 pass-thru programming to manufacturer software. They are what you need when a used engine, transmission or body module has to be matched to the vehicle.

The range spans bench and OBD programming from Xhorse VVDI PROG, OBDSTAR DC706, Autel MaxiSys with MaxiFlash, Launch X431 SmartLink and XTOOL. Check model coverage before buying, as programming support varies considerably by platform.
