Ca18det ECU question

[Guffed]

Hi, I have a question about the ECU...I'm in the process of a swap, foolishly, I thought I could complete the swap without needing an ECU and wire harness for the ca...So I used the Ka stuff. Now my car is 99% complete except for the wiring...I wired it and it will turn over and it will spark but all 4 spark at the same time ( yes it is grounded)...I think my problem lies in the ECU and the harness (not sure about the harness yet)...So to my question, do I infact need the CA ECU and if so, can I use an SR20 (uses coil packs too right?) ECU or make the KA ECU work? Thanks alot,
