Yes, but are you getting fuel injected ? are you getting a spark ?

Confirm before making assumptions. You could maybe just have drowned the plugs or something. Have you configured the ecu correctly ? Does the ecu seem to be alive ok ?

Well if you have fuel and spark and comms with the ecu....it would be unlikely you have blown the ecu

And again, have you drowned the plugs ? Replace them.

Has this engine ever run correctly?
If not I suggest you don't get hung up on the idle valve just yet.
