Are our ECU personalized for each car. I think I am having a connectivity issue.

Re: ECU question

If it is the wrong ECU the car will not start... period. The ECU is programed to the car's VIN. Who did the tune? It would be VERY odd that you got the wrong ECU back...

Edit: it wont hurt anything... it just wont start.

Re: ECU question

Try unpluging the connectors and then pluging them in again. I think I remember reading that had worked in a similar situation. Worth a try.

Re: ECU question

Is this one of our tunes?????

The ecu is VIN encoded, and will not start on another car.

That being said, most of the time, its a plug issue, with not making sure the plugs are securely and properly seated.

Re: ECU question

I was runing into some connectivity issues with the battery.
NOTE: Leaving a battery unplugged for ~2weeks in humid weather can lead to a poor connection (despite the fact the terminals look clean). I cleaned off the terminals to ensure a "fresh" connection, and now the car runs just fine.
