Do I Need to Replace DME Chip ??

My defective ignition coil-pack cooked an ignition transistor in the DME of my 1995 318i Automatic. I have replaced the ignition coil-pack, and I have a used DME ordered, which should arrive in a few days. The used DME came out of a 1995 318i Automatic, and the Bosch part numbers all match perfectly. Before the DME module arrives, I am going to change the system relay, as well, just to be on the safe side.

My question: should I replace the DME chip in the used DME module, that's on it's way, with my original DME chip from the stock DME module from my car?
Or, should I just try the used DME module, as is?

I've boned up on changing the chip, from PelicanParts site, and it seems like an easy process.

Any other words of advice before I turn the ignition key?

thanks

The chip may be fried too bro, i would just replace it all as one since the numbers match up you shouldn't have any problems.

SIngring:

Please contact me to know where did you bought the DME,I need one too.

arrambide, lemme know whats going on with yours car. If your gonna replace chips you need to make sure you know what your doing. They are very sensitive to static electricity and can break before you know it.

I am not whose will do that work...

The problem is that, since december, the car was in a dealer and check all the sensors and told me that the problem where the DME or general brain unit and the cost is about $1300dlls, so i decide to take the car to other specialist and now, 6 month later, the problem is the same, change sensors, made many tests and the diagnostic..............................DME.

I need to find a complete DME with exactly the same numbers but complete I am not saying that I need only the chip.
