Can the avg. guy install a chip w/o any problem?
I just got Mark's chip and I have visited Bruno's site and I am just wondering can I do this without messing up the coputer. I just check with my mechanic(both of them) and they can't do it until weekend. That's an eternity to wait after hearing all the news surrounding this chip. How long will it take a novice and would you recommend me to just go ahead and do it? I have a 535IM- just tuned up and running great. What scare me the most at the end of Bruno's site he said if the car doesn't start you could have fried the computer-ouch!!!!!!!!!!!!!!
There is no need to disconnect the battery
Just be certain that nobody can turn the ignition on while the DME is out of the car.
The cars with the single circuit board DME's are very easy to do, but I had a significant problem getting the dual circuit boards separated in my 1991 525i. Once I knew what I needed to do, it was very easy after that.

Thanks Ryan, that is good to know. I had been
under the belief that this could fry some of the electronics in the car if it happened. I really didn't know under what circumstance it could ever occur, but I always made certain I had all the keys to the car whenever I had the DME out. I read it somewhere that you didn't want to let it happen.
I think I will still be careful about this, but I appreciate your letting us know that it caused you no problems.
