Fried my ECU

[ethergore]

So I accidentally fried my ecu today. My curcuit open relay for my fuel pump went out and I tried to fix it with a standard relay. Somehow voltage got sent to the ecu resulting in a really bad smell. 

I am in the US and wondering if this can be fixed or the board replaced. Is there a person in the US that can repair or replace? Would I be required to just buy new? Thanks.

Here are pictures.

looks nasty, but I think you just need to replace stepper chip

That would be awesome.  Could I just order a chip and take it to a repair shop locally?

Is this board still working in some way?
If not, I would try to understand whay have happened and buy a new board.

I didn't think to try to see if it still worked. I know zero about electronic components. I don't have a test bench but I could hook it back up to my car. Is that safe?

That looks like a replace to me. The PCB is damaged quite a bit. If you need the stepper outputs, replacing that chip is unlikely to be successful.

If you have enough spare outputs that you can move the function to a different output, it might work to just remove that chip. Cut the legs with the smallest diagonal cutters you can find and then remove them one by one, or just cut flush to the PCB.

Looks like a DIY board with the connector screws and axial resistors. If so, our gutswap replacement deal doesn't apply.

If it was a fully assembled and tested purchase, email info@vems.hu including these pics and the serial number. They can give you a replacement cost.

Thanks,
