What is the difference between GODIAG ECU GPT Boot AD ECU Connector and OBDSTAR P004 Adapter? Which is better?
OBDSTAR P004 Adapter is in default in the OBDSTAR P50, DC706, and X300 Classic G3 package.
It allows you to connect a breakout cable for OBD.
Some use the GODIAG GPT adapter to replace the P004 adapter.
P004 Adapter is just a cheap breakout box. Any breakout box also works.
ECU GPT Boot AD Adapter is much better and easier to use, and does more.
GODIAG GPT Adapter has the 120ohm built-in which the breakout harness doesn’t. It is easy to add 12+, 120 ohms and pins are somewhat decent, making life easier. To connect CDA, PCMFlash, and other tools on the “bench”, no need to carry so many other adapters. That and GT105 and GT107.
Users have been using the GODIAG GPT Boot Adapter instead of P004, the P004 is just cumbersome to use. Much easier this way.
