Gear/Converter Swap - Computer Qs
I didn't plan too well and now I have (as most of y'all know) gears and a converter, among other things ;) sitting in the garage. And now I'm getting itchy for the install, especially considering I pulled a 12.564 on Thursday :D
I'm loaded now and know I gotta contact Steve and send it back to a reprogram, my question is this.....If I can get them installed relatively soon and wait on the computer:
what are the issues of driving around without the new program?
Thanks!

Re: Gear/Converter Swap - Computer Qs (Mean Green 2000)
If you weren't switching the gears, it wouldnt be a real big deal. Since you are changing the gears, and your transmission shifts based on vehicle speed, your shift points would be HUGELY messed up without proper PCM programming. The PCM programming corrects the speedometer, which in turn allows your vehicle to shift at the proper RPM. I know a few A4 guys have made a gear change before PCM programming and their car was barely drivable.
I suggest getting the Powerloader sent back just as soon as you can so that you can get the install done when it returns. I honestly dont think you would have any fun at all with your car with the new mods installed if you were waiting for the PCM programming to show up.

Hate to see those gears gathering dust (!), but I don't think its worth it to install now unless you know that you will get your reprogram in hand quickly. The car will throw codes, and it will not run right. There are A4 guys around here who know the details.....

Re: Gear/Converter Swap - Computer Qs (MattG)
I would agree with MattG on this one. I drove mine for about half a day before I got it loaded and basically it still drives but it won't shift at WOT. Otherwise its pretty normal. Sorry to say but I think you should wait until the loader comes back.

Re: Gear/Converter Swap - Computer Qs (MattG)
Mean, I agree with the 'get the programming ready first' advice. A nit though... The speedo does not require any programming to be correct. However the shift points do need to be corrected since they are now at a different RPMs with the new gears. This thread from a few days ago might be of interest:

Just finished the 3.15 to 3.42 upgrade to my 2002 yesterday. I am in the process of starting a post with details.
You can look at my web page until I get the post finished:

"Mods" section; 3.42 details.

Re: Gear/Converter Swap - Computer Qs (Mike Mercury)
I had 2.73 and went to 3.42, now maybe, I should have gone 3.73??? If I had 3.15, I would not just go for the small increase, 3.73 would have been a must. You will be sorry, like me.
