Change 4pcs 74hc125 whit 74hct125M smd in your carprog , and all will by ok.

Hello, change the 4 IC 74HC125D is the only modification to rework carprog 7.28?
Thanks for your help

What not work? Antenna is working? Can bus is working?

Hello, i have a clone carprog using solfware 7.28. Since i received it, it is impossible to read eeproms 95160 and 24cxx. I so used the software with airbag, but the ID of the Eproom is not recognised. The eprooms were desolder from the pcb and i used the A4 and A5 adapters provided with carprog. I have verified that the wires were correct with a multimeter (continuity test). I don't know if the changes of the 4 IC will help to read eprooms. I very dissapointed

I don't test if antenna and CAN bus are working? How do i make it?
Thanks for your reply

First and most important of all is to change 74HC125D to 74HCT125M on your carparog, i have good clone (good pcb) but still did not read some I2C,95 ,MCU. I bought 74HCT125M at farnell change all 4 of them and it is ok now. reading without problems.

Hello,

What's a good pcb of carprog? COuld you send me a picture?

Most people flash to 8.21 and make rework like on many pictures in this thread

Hello, thank you for this reply. I will send you some picture of my carprog. Then , you will tell me if it is a good pcb. Can you give the main changes to make at the rear of the pcb because on the pictures, it is not easy to understand (remove some capacitors, remplace by a what? repair the hole line missing?
Thanks

Hello,

I have a clone carprog 7.28 but i don"t know the version of the firmware. Do you think that is impossible to read 24xxx eprooms even if i change the 4 IC 74HC125D by 74HCT125M.
Thanks

That's 1 of a few mods you can do you can try this but I haven't tested it.

i tested it and work perfect.

Hello, could you explain me the changes that you made on your carprog for held reading and writing eprooms? Add a 120 ohm resistor and change the 4 iC 74HC125D by 74HCT125M?

Here we go this is good start and yes change 4x 74HC125D to 74HC125M i will post some pictures of the other mods shortly hope this helps don't forget to thanks and rep those who have helped you

Hello, thank for your reply. Do you know where i can buy some good 74HCT125M?
It is possible to buy on Ebay? Some friends say that the components on Ebay are not original and are bad. Thanks
