Perhaps some older products using PC Parallel ports, though you'd need to find a junker PC of the era with old OS, etc. ie ST7-STICK or ST7 ISP

As I recall these devices had programming protection against miscreants.

You might be better using ODBII methods, or frankly on scene boards covering these topics.

thank you. I will check it out I have also on my desk programmer for STM8 and STM32. I found in the ST7 softwarfe that this programmer is supported so I installed the softweare but there is only LPT connection mentionined and I do not see an USB option :(

>>I do not see an USB option..

Yeah, you're dealing with 15+ year old tech, there's probably not much market for such things in the commercial space, and probably not at the price point you'd want.

Check what the chippers and garages are using
