engine swap cause check engine light
I have honda Civic vti oriel 2001 in pakistan
It originally had Engine number D16W9 which is a 3 stage V-TEC and car's ECU was programmed according to that.
Later on I swapped that engine with D15b which is 2 stage i mean have only one vtec solenoid on its block.
now problem which i want to discuss and want its solution is when ever RPM goes above 3000 check engine light cones on.
kindly suggest me some solution

The ECM does not match the engine.
You either need to install a correct engine, or somehow install an ECM and wiring that matches the engine you installed.

yes u r rite
actually ecu is for engine d16w9 which is three stage vtec(02 solenoid)
1st stage active at 25000/3000rpm
2nd stage active at 5500/6000 rpm
but now i hav engine d15b ..having one solenoid which active at 4500 rpm
now i have one solution but it need to be discussed before execution
if i connect the only solenoid at ecu pins which is used for 1stage vtec. then ecu may activate it at 3000 rpm?
is it a right solution?

The ECM looks for an appropriate response after it attempts to activate a VTEC solenoid.
If it does not receive that response it expected to see (because your current engine does not have the same features as the original engine), it will set a fault code and go into a restricted driving mode (limp mode or similar)
