308 brains

Hi friends
I bought the 308 hdi, I went to the service with the engine malfunction light on, although there was no particle, the vehicle was showing a particle malfunction on the device and I went to a cerebellum, and the owner before him put a brain of 110 in the 90's car and said that if the brainman would not throw the 90's software, he would raise a brain that he had. are there? Thanks in advance

You can know that you encounter problems as you say, when the ecu is different, my software is different in the software. To get rid of software, take your ecu and change it to 90 acu head-on.
