blown pcm. what to change?
 

well had the car to the main stealers today and they have confirmed that the pcm is fooked. i am going to source a 2nd hand unit but what do i need? is it pcm, immobilizer and key or just the pcm? where is the immobilizer box if i have to access it?

thank you

You need As-Build data, PATS data, Pass-thru device, and latest PCM calibration.

the data is easy to get (small fee), the Pass-thru device is the tricky part. and most of the time only dealership has it *cuz its expensive*

Not sure I understand mate. Can't I just remove the PCM from another car and fit it to mine along with the matching immobiliser box and key?

Thanks

nope. each pcm is mated to the car it came from. Now if you get ALL the wireless/security system boxs and the keys--then yes it should be a swap out. But that would be a pita to do.

Do all 2004 ecus work on other 2004-2008 cars or just 2004 ecus with Racing Beat software?

I have the later and it works on my 2005; and it worked on the previous owner's 2005. The security light on the dash flashes for a couple of minutes but no other known problems.

So, maybe you can buy a 2004 or a 2004 and get RB software.
