Default Swapping out a VTEC Engine with a Non VTEC Engine

I have a 2002 Civic with a ruined D17A2 VTEC engine. I have found a very low mileage D17A1 Non VTEC engine. I understand that I will have to use the intake and coolant passage housing from the ruined engine due to the EGR valve. Question is, since the ECU was originally designed to run a VTEC engine, will I run into ECU problems trying to run the Non VTEC engine.

When the CEL is on for any reason, the ECU goes into limp mode, which will impose a rev limiter and also likely hurt your gas mileage and emissions. So you really should replace ECU with a non-VTEC one.

Thanks All........I believe it will be less of a headache to look for a VTEC replacement.
