Hi I've got a Mazda 2 1.4 diesel 2004 I recently changed the ECU sid804 I tried to do a eeprom swap but when the ECU is connected to the car the immo light flashed and car does not start .
I presume the immo data is also stored in the flash that's why it's not started do anyone know if I programme the keys to the new ECU should it start .
New ECU was like for like with matching part number .
Thanks
