Help identifying this device

[Kalic]

Would like to find info about this piece, I'm having trouble finding anything on it since the searches I've been doing online have come back with useless results that don't seem to match what I'm looking for and that is probably due to the fact that I am unsure about what the exact name is. Basically all I can tell about it is what's visible in the photos which unfortunately gives little detail but hopefully someone can still help me identify it somehow

this is an old revolution chip for loading custom tunes on to EECIV/EECV Ford PCMs.

Ok, thank you for your help. I honestly have no knowledge of how these things work. is there anywhere I can find a little more information about it?

theres lots of eec chips out there, all work basically the same way, its a piggyback device that controls what the pcm does in real time.
