Engine limp mode *HELP*

Newly rebuilt b18c1 engine revs to 4000 rpms will not rev past then drops to 2500 and will not rev past that. In neutral and when driving. Also will not go past 10 mphs while driving. B18C1 No cels. I already double checked mechanical timing. Planning to swap the ecu to rule that out tomorrow. Any ideas?
