Over the winter I did a complete motor swap d16y7 to y8 I used a auto wiring harness with the p2p ecu the motor will go to red line in 1-3 but 4th and 5 th seem to lose power feels like it’s being governed by the ecu it gets to about 4grand and it just falls on its face is it the ecu and if so can I unplug a wire or do I need a new ecu

It’s not throwing any codes it doesn’t hit a limiter it’s just low on power almost like the ecu is governing the motor it’s a 98dx Motor is from a 97ex the head is from a 99ek The harness is from a 99ex and the ecu is p2p
