My worry is that the computer can't do it's job unless it has the input from all of the sensors. The whole point in going EFI is for efficient engine operation.
Thanks again for your input.
A marine computer for any year wont give good performance as the fuel mix and timing curves are WAY different due to the way a marine engine moves a boat through water. Dont waste your time.If it isnt setting any sensor codes dont worry about it like F Bird said.
No cats and no smog pump will only affect performance in a minor way. You would probably not ntice. You do want an O 2 sensor(or both) hooked up. If it had down stream sensors, leaving them out wont affect performance , all they do is measure cat health.
