How do you guys potect your intellectual property from prying eye since we all live in the technological days now. How do i use some sort of encryption on chips i've made?

 

Nope sorry It could be doable but like any encryption it can and will be cracked

 

I understand any encryption can be crack.Im looking for something agasint too savvy users out there

 

If you're dealing with OBD1 Honda's, who really cares? Personally, I feel that if a customer pays me to tune their car, they are free to do whatever they want with "their" program.

 

There isn't a cost effective way to copy protect a commodity EPROM from copying. If the ECU can use the chip, someone else can copy it. The end.

If you want to protect the contents of the chip from someone else being able to read the raw binary and open it up in your editor of choice, that's a different story. It's actually rather trivial to do, but I'm not going to tell you how to do it because if it matters enough to you, you'll learn enough assembly programming to do it yourself.

 

The best way to protect the tune you give someone is to make your own ecu. Its like protecting music - the best way is by far the most expensive/hardest way, so you really have to rely on courts and promises...and threats.

In the end, you're providing a service, not a priceless work of art. I can see wanting to protect a 3 minute song that can't be perfectly reproduced w/o straight-up copying. Any tune you give a Honda CAN be totally reproduced w/o seeing the original data. Therefore you are providing a service anyone else could conceivably give.
