What is wrong with yours? You can open the computer by removing 8 Phillips head screws. Have a look inside and see if the circuitry is damaged. If it is, you may just need a new unit. I'm not sure if anyone repairs them.

Their listing ended on ebay but if you contact the seller they were offering MegaSquirt repair service

Pardon Our Interruption...

I took the screws out and inspected the board. It appears to be soke diode or some capacitor or electronic piece .

Can you get a picture of it?

Fricken Tantalum capacitor, they fail shorted and go boom.
Look at page 172 of https://www.msextra.com/doc/pdf/MS2V30_Hardware-3.4.pdf

What exactly am I looking with in regards to the chart? Lol. I appreciate all the help

I'd look on page 197 of that manual Steve linked. It looks like it's your C16 that exploded per the diagram and your pictures. If you reference that to the chart below it gives you the description and the digi-key part number if you want to order from them.

I will do that now. The ecu smells like an old computer . Will this component cause a no start? So glad I came back here!

I'm not familiar enough with megasquirt to say if it will cause a no start but even if it doesn't it definitely needs to be fixed for something. If you review the wiring diagrams in the manual you may be able to figure out the function of C16.

Also just FYI that Capacitor has to be installed a specific direction. There should be a + on one of the board holes

The other parts in that circuit should be checked to make sure there wasn't additional damage.
If you don't know how to do that it might be safer to find someone who does.

The section in question looks to be the +5v regulator for the board. There is a poly fuse right after but that's why you check, cause it might be open or wasn't fast enough to save everything downstream. There is also a regular 20A ATO type fuse in front of this regulator that could blow when the cap did.
