As far as resoldering the ECU, I think that's exactly what HP Tuners did with their ZR1 ECUs.

correct.

We threw an app together and used VIN changes as our first item to change... might work for you. Have not added CAN support, yet. (got busy with work) Will be supporting a lot of other things besides just VINs, that was just an easy thing to start with. https://play.google.com/store/apps/details?id=...

Opened up another project I did back in '06.. This one is a circuit that allows you to replaced a 44 pin PSOP flash (e.g. Intel 28F400) with multiple chips so that you can switch between them. The switch watches for line activity to ensure that you do not switch over in the middle of a Read / Write ...

After suffering to get the J2534 working, the PDU won't be a big deal. It is essentially just another API to implement which essentially performs the same sort of tasks, but with different methods / return values, etc. Increment effort. Would make sense to get J2534 cleaned up first from a performan...

Some answers to questions: - Cost (my) assembled in a small quantity is going to be somewhere around $75-$100 w/o enclosure. Large quantities should be in $50 - $75 range. - If I go through the trouble of bulk ordering (e.g. putting money down, etc.) I'm going to charge a little more than my cost to...

for GM, starting with some MY17 cars, they have switched to a 5 byte seed/key. In addition to the algorithm number discussed above, there is a security table now as well. Each security table has N number of algorithm rows similar to the old functionality. (a lot more to brute force) Additionally, th...

AVT interfaces? How passe'
Coming soon....

For "thousands" of cars by different manufacturers? This is just a bullshit product.

Sorry for late reply.

These Saturn PCMs were made by Motorola.

If you give me VIN #'s for your Auto and for a Manual, I can pull you files.

Pretty sure I have mapping & checksum info as well...
