DIY ETM replacement
 

I have a 99 s 80 t6 that is spitting codes for the ETM, it's past the warranty but I got 180k out of the thing. Lucky me right.... ha no. Anyways. I searched for threads about replacing it yourself but didn't find any. Thats not to say the're not there but I couldn't find any. So has anyone replaced the ETM with a rebuilt one for xemodex? How hard was it? Will I have to do anything to get it to link up the computer?
