K-Pro in a K20a3...Limp Mode, Cannot load map.... HELP!
Vehicle: '93 Civic Si
ECU: K20a2 with KPro
Mods: K20a3 with DC Sports Header. Hybrid harness, fuel rail, pressure regulator. Otherwise, motor is stock.
Problem:
I have a K20a3 swapped '93 Civic hatchback. Car runs in limp mode, check engine light is on, will not rev past 4000 rpms. K-Manager is reading the ECU fine, it reads ignition, but whenever i try to load a k20a3 stock map onto the ECU it gives me the error message "Upload Failed!". the LED's on the ECU indicate that the ECU and K-Manager are communicating just fine.
I have consulted a couple local tuners around me and one told me that the k20a2 ECU, even when equipped with Kpro is not compatible with the k20a3, and the other told me it should be just fine since it has Kpro.
Regardless, either way i am stumped.
Thanks in advance for the assistance

take it apart and check the board some times the screw backs off and the board seperates

no security on the ECU.
the fellas at hondata advised that i check the wiring. since the car was wired by someone else, and it resembles wiring a 4yr old would have done, i am going to have the wiring completely redone and see if that does anything.
