This help fix the cloned Carprog to get it to work (e.g. read security codes or read flash) as the original.
The bad Carprog clone:
many members with Carprog clone can say it will work have to tweak it ,and read the manuals really only for mcu usage. I have retooled and remade many of my own adapters , also changed bridges , caps , oclis crystal etc on mainboard also flashed to 4.74 firm . all the N/a are gone and eprom and mcu reading is great no faults. also fixed ground plane and insulated board from aluminum case with k tape. its working fine now but has a nice coat of dust on it.
Here is what you can try to rework Carprog PCB:
Check A1. You may need to improve the work can.
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.
If it’s difficult for you or you fail to rework, perhaps you could buy a HQ Carprog programmer at the best price (Forget the cheapest!!! you will get what you pay for, especially for China clones)
Good luck! Try on your own risk!!!!!
