Hi, I have a renault megane 2.0 16v convertible 2007 with sagem s3000. Original ECU is damaged and will not read. I put a replacement ECU in and original EEPROM. Car starts bet revs erratically and shows fault on throttle tracks. I have fitted replacement throttle controller but same fault and throttle tracks appear to be working correctly. I am thinking the map maybe incorrect. Does anyone have a map for this vehicle or offer any advice please.

Will not be advisable to clone out the serial flash memory or has broken and place it to the new and you would have solved your problem, greetings.
