Hi. I need and opinipn/advice. I took my eclipse cross for ECU tuning, while they are doing a read out of the ECU, an error o cure at around 99 to 100% of the process. Now my dash is showing immobilizer service required,close fuel cap and lid, hight temp service required. We took it to the delarship and they said that the ECU, KOS, and Etacs needs to be replaced a at the same time.its either we buy from them or buy a set that came from one car. Replacing the ECU alone won't work as per delareship. Is it true that i need all of these and if i opt to buy second hand tht is should be from one car only? Thank you your your input. I'm getting frustrated. I attached the items that needs to be replaced.
