What is GODIAG ECU GPT Boot AD Programming Adapter?

GODIAG ECU GPT Boot AD Programming Adapter is a professional adapter for customers to read and write ECU data without disassembling the ECU using the OBD2 Bench or GPT Bench method or disassembling the ECU and using the Boot method. It is equipped with a short-circuit-proof BOOT resistance board connection line to protect the ECU. It can be used with J2534 devices and PCMFLash software.

What is the advantage of GODIAG ECU GPT Boot AD?

1. Resistance is fixed, easy to check

Normal resistance used by everyone is color ring resistance, so every time I have to go to see or measure. Or you can just put it away. Otherwise, you have to repeat the same thing every time. The fixed resistance plate can be picked up each time it is confirmed.

2. Has long enough cable

Sometimes, the length of the color ring resistance is not enough to add an extension line and you have to find it. We have equipped 15cm silicone wire with high-temperature resistance and anti-scalding.

3. Can prevent losing resistance [anti-lost resistor design]

Because the color ring resistance we often use has little resistance, it’s not easy to find.

The Godiag boot board resistor is already on the board. Mark the value on the board for checking every time easily.

4. Has an independent resistor board

The resistor board is independent, and if it is the value you need, connect directly.

If you do not have your own resistance, you can operate in series and parallel to reach the value you need.

5. Supports OBD/Bench/GPT/Boot modes

It supports all modes incl. OBD2, Bench, GPT (no open cover), and Boot (open the shell to connect the resistor).

6. Supports ECU read/ write, OBD2 diagnosis, programming, coding, etc.

It not only can read and write engine ECU, but also can convert IMMO, airbag, and others into OBD2 diagnosis, matching, programming, coding, etc.

7. Supports standard OBD2 protocols

The adapter has been prepared with standard OBD2, PWM+, PWM-, CAN+, CAN-, 120Ω, K-line and other communication protocols

8. Easy to plug and use

These terminals use the special ECU connection terminals. The ECU is silky when plugged in.

Moreover, the boot CNF1 connection method is also different, the traditional is a small clip, the clip shows too much metal surface, and it should be protected when used. To avoid clip short circuit damage ECU, the Godiag GPT Boot Adapter adopts the plug-in method, and our sockets are also selected. Just gently press it by hand as it’s a lever structure inside. It will be not easy to unplug once plugged in.

It is lighter when used, and the contact is good, and the outside is insulated and cannot be short-circuited.

9. Compatible with most ECU programmers

It cannot be used alone and needs to work with ECU programmers such as Foxflash, PCMTuner, Tactrix Openport 2.0, GODIAG GT100 OBDII Breakout Box, GT100+, etc to read and write data.

Only Scanmatik 2 PRO for PCMflash allows you to form the GPT1, and GPT2 signals necessary to work with Module 71.
Other devices like Scanmatik OpenPort 2.0, Mongoose JLR, MongoosePro JLR, Teradyne GNA600 (VCM 1), and Mazda VCM 2 support OBD2 or BOOT 53 mode to read and write ECU data.
