Hello, I have Renault Espace  3.0 2003 year, automatic,  with broken ECU Isuzu Denso.  I have another second hand Ecu from another Espace 3.0 but with different number. When I put new ECU in car, car crancking but no start. Immo red light solid, not  turn off. What  I have to do to start car. Does I need to replace eeprom or  flash from old ecu to new . Thanks in advance

If I am correct, there is the problem with immobiliser. Immo light is solid on because code for the card and central unit is okay. But the problem is when central unit sends code to ECU, ECU doesen't recognize the code and it wont start the car. I am shure reprogramming the ECU with right code will do the trick.
