WARNING: LS1 Edit & GM Column Lock Recall Don't Mix

WARNING: LS1 Edit & GM Column Lock Recall Don't Mix
Maybe this should be a sticky.
A word to the wise: if you have an LS1 edit program on your car and take it in for the column lock recall, they will reflash your computer and you will lose your programming.
If you flash your car to stock before taking it in, that does not mean you can put your old program back in after you get it back. Apparently, they change a sequence i.d. # when they do the recall flash. When you try to program over it, with the old sequence i.d. #, you cross-program the computer and the pcm will need to be replaced.
Once you have a new computer, you need to send LS1 edit back to get it coded to your new pcm. You will also need to upgrade to LS1 edit version 1.5, if you want to keep this kind of thing from happening again.
Note: if you have version 1.5 of LS1 edit, it won't let your "cross-program" the pcm. But if you have one of the older versions, beware!!!

I had the column lock recall done at GM on my 99 A4 C5 and honestly never even thought they might reprogram the PCM but when I got the car back it barely ran since I had h/c and bigger injectors but I read the PCM with edit and was able to reprogam it fine when I got it home. I know they did the full recall since the column didnt lock anymore after I got the car back - on A4 cars its disabled completely.
Who knows, maybe its different with a A4/M6 cars or by model year or I just got lucky..

Remember, you should read your pcm often anyhow and make changes to the read file.

It is simple. The column lock fix gives your PCM a new revision of the code. You need to re-read your PCM anytime your PCM code is changed through an update. This particular revision of code isn't added to edit until 1.4-1.5 I believe therefore you will need the newest version of the program. This isn't rocket science and they mix just fine unless you don't understand what is happening.

Why would you want to not have the column lock? Is there a danger of it locking up while driving? If not i'd still want it, harder for theives to steal, especially if they brave enough to try and tow it away ect. Now they can just straighten out the wheel.

I'm just curious, because I've been using the same read file to write new tunes for my PCM for the last 23 reflashes or so. I really don't see a problem with this, but am I wrong? Why would it matter so long as your inital read came from your PCM?
Please advise.

On the auto cars, they figure since the shifter is locked, the recall disables it completely while on the M6 cars they put some updated parts in and update the code.

To answer the questions about the column lock, it is for the Vettes. The recall is performed differently on automatics versus sticks. On a stick, they reflash the pcm. There is a possibility of the column locking WHILE YOU ARE DRIVING.
As for LS1 Edit versions, Ken from carputing told me 1.5 is required for a pcm that has been flashed pursuant to the recall.
Did I know that I could read the program in my pcm and re-modify it? Yes, I knew that. But what a pain!!! I keep all my LS1 edit files on a laptop that is never connected to a network OR to the internet. I have several backup cd's and floppies - I do not need to worry about my files getting corrupted. I have extensive modifications done to various tables and several other settings. I know I can copy some of the tables in, but still, what a pain to do that if I don't have to.
Apparently, the GM internal memo tells the techs that flashing the pcm after the recall is a problem, but they are not telling the customers. Plus, how many of us are actually going to go into detail with the dealer about all the LS1 editing we have been doing on our cars?
