hello my friend i have a 97 asti 4g93 motor and i whant to reflash the car but dont now where to connect the pin 79 (diasnostic) from the ecu on the obd2 port is there a way without the tactrix 2.0 port to reflash the ecu with some other interface cable and how ?

Evoscan or ecuflash software ?

i have a 99 ecu witch is MD plastic i have the tactrix cable for reflash but i have tried it and it doen't read the data from the ecu how is the right way to do it and if i need another cable to do it ?

remember is the same ecu as evo 5/6 but non turbo

thanks for the help in advance
