1.The computer used for the device cannot be connected to the network, nor can the device be upgraded. if it be locked the factory will charge for repairs.
2. The connection diagram is depend on the ecu model,Look at the model of the cpu chip for ecu select., select the software menu to read and write ecu, all 71 options ecu no need to open the ecu connection boot line. But you need to connect the GPT0 and GPT1 lines.


(For example, I removed  the ecu from the car is edc17 c54, then my ecu cpu is tc1797, connect the ecu according to the wiring diagram I provided, and do not open the ecu. According to this connection diagram, you must connect gpt0 gpt1 , the software chooses this 1797 cpu option)

3. 53 option is to open the ecu connection boot point read data mode, and the item se140, se140-b mode is the same,we must first read the password and then select the read data

The advantage of reading ECU without removing the cover:
1. Easy to operate, you can read the data in about 5-10 minutes without removing the ecu cover. Unpacking an ecu to see the technology and equipment, generally taking off the ecu is about 20 minutes or more, it is normal to remove the ecu cover more than one hour or destroy the ecu cover.
