okay well today while trying to tune my car i notice when i turned the key in on position the pump didnt prime, so i was like what the **** i broke something or wiring trouble so i sat there and ran through the whole car only to figure out after swapping ecus thatmine is messed up, so i took it apart and one of the small diodes or whatever are jacked up and on the buttom of the motherboard its burnt like, QUESTION IS THE S300 UNIT STILL GOOD AND IS IT ABLE TO BE REMOVED AND PUT INTO ANOTHER ECU

The S300 is probably ok, but the best thing to do is to try the S300 in another ECU to see.

well either way its not to possible to do so, due to the way the s300 is pinned

Obviously, it is possible, you just either need some header pins, or you need to prep another ecu..

What component is burnt in your ecu, or what location is it at?
