swapping ECU ( trying to anyway )
 

I need HELP . I have a bad ECU unit in my 2004 RX8 . Bought a used one . Will not start . It shows it is immobilized when I loaded my COBB ( COBB will not reset it ) . Dealer says he can't reset it , I have to buy new one . Can I get the ECU reset or do I have to buy a new one ???

why did the dealer say no?

I figure they want the $771 , ( I live 45 miles away , I called them )

well they will want to charge you to get it "married" to your car. probably bill you a couple hours labor.

I am asking the place I got the ECU from for the ignition key ( going to cut the KEY off , make a blank key and see if I can trick it so I can get it to the to the dealer and program a new key )
If that doesn't work , I will put the old ECU back in and swap it when I get there .

You need to have the new ECU programmed to mate with the other modules...you will need your cars " as built" data that the dealer can get from the techline.

It takes about 1 hours labour to get it up and running if everything goes well and the tech knows what he is doing

You will need to bring your keys with you :)

Good luck

You can get the As built Data for like 30 bux. then you can give it to your dealership and it should work.
