2000 integra k20z3 swap. Cyl 2 no spark. Tested continuity on all 3 wires and tested good so leads me to believe ecu is bad. Is there a certain spot on ecu that fires cyl2 or something along the lines of that so I know where to look at inside the Ecu.

Have you tried the ECU on a known working vehicle?
You will not be able to see anything inside the ECU even if it is damaged.

Yes I tried it in my friends car which is a 02-04 rsx with a k20a ctr swap and it seemed to run it on all 4. Same tune I’ve never changed tune. Is there anything weird about putting a k pro in a prd ecu? Cause that’s the board my k pro is in. Compression is good on my motor. 210 on all 4 cylinders… I’m so lost.

If it worked on a different vehicle, then you probably have either a wiring issue, or a bad or clogged injector.
