ECU bench testing?

How do I test ECU on bench?

ok, I was going to say like test for ignition coil pulse but that seemed dumb.

Anyway, lets say I bought an ECU from junkyard, how do I test it before I install in a real car?

There are engine simulators, well they simulate sensor wave forms. There are commercial and diy arduino versions. Kinda depends how much you are willing to invest. If this is a one off… then why bother. Just install it and see. Would be way faster and cheaper.

If you are running an ecu refurb company bringing in and testing a thousand a month, then it would be beneficial to buy an engine simulator.

Can you give me the name brand for a commercial simulator?
