I purchased this 2003 Civic Si.
And someone has tampered with the ecu using HONDATA; it runs rich, and they appear to have tampered with the radiator fan activation.
The prior owner cannot be found.
So, can the dealer flash this ecu back to factory settings? What is the price?
Would it be plug and play if you program it, or will it require further programming to function on my car?
