Question A4 to M6 question

I want to swap an M6 into my car and im buying all the parts one at a time......I know all the parts I need (I have them on a written list marking them off as i get them lol) and I'm very mechanically inclined, my question is......what part of the swap will be the most pain in the butt??


I'm assuming it will be mounting the fluid resovior to the firewall??

I have LS1Edit, so I'm capable of flashing a new file into it from an M6

Any info or tips is appreciated!!

I'm planning the same job and for now it looks like the wiring + reprogramming will be the most difficult part.

How will you flash a new program using LS1Edit? From another car? But then you'll load the other VIN also. Do you have more than a license for Edit?

We can share some info about the swap, if you want..

Wiring. It's not a hard job but, that's always taken the longest.

Wiring will take me 5 minutes......Thats what I'm best at, I used to build large custom car audio setups so I'm good with wires.

Reprogramming will take no time at all......all I have to do is get on one of the bin file sites and get a program for an 01 M6 camaro


Any info on what part of the......I guess I would say "fabrication" would take the longest??

I don't know about the fbody's but the Vette's it's the brake pedal. THe floor has a perferated circle in the insulation where the clutch pedal goes through the floor so, that really easy.

Yea.....I saw the same thing in my car where the clutch pedal will hook up. Two little dimples for the bolts of the resivoir.

The only parts I haven't looked at to see if the factory "outlined" it is the hole for the lower shift boot where the shifter comes up through the floor. That's something thats going to need to be a perfect cut because the boot needs to fit nicely in the hole and plus it needs to be centered on the shifter right. There is no hole like that in the trans tunnel (sp?) of an A4 car.

Yeah, you will have to cut a nice hole in the tunnel for the upper boot. What I did was buy the upper boot which has a hard lip on the bottom of it that's shaped just like the hole you need to cut. I took the boot and pressed it against a piece of carboard real hard which leaves the exact outline impression on the cardboard of the hole you need to cut in your tunnel. You cut around the outline of the carboard and you have your jig for the hole.

I made some precise measurements from my friends M6 car and placed the carboard down according to those measurements and I have the same exact whole in the same place as OEM.

For me, the the hardest part was the pedals and getting them aligned just right. The resevoir was cake, it's just held in with one bolt or or a factory plastic expanding fastener.

DanZ28, what about reprogramming? Are you using HPTuners (= possibility to reflash the PCM).
I have Edit and I'm stucked with this issue.

You can reflash with Edit......you download an M6 Tune from the same year model and then when you got it on your computer, you change the VIN and upload it to your car. OR there's several things you can change in the tune to make it think its an M6 (vehicle speed sensor is the main thing, with the second thing being that when you have an M6 or TH350 with an A4 tune, your car thinks its in Park or Neutral all the time....so it runs base timing, fuel, and limiters)

Would reflashing the PCMM by ANY chance cause me to fail Emissions?

Well, we don't have emissions tests here in Arkansas but from what I understand, if they read the computer from the OBD II port.....they are looking for the proper VIN and SES codes.

As long as you change the VIN to match your car then you are fine.

If you're setting a SES Light then you will fail emissions anyways, and with a tuning program you can acutally DELETE the SES codes and make the light go off, making you pass emissions tests.

This is helpful if you have any mods that will throw a code in the computer (egr blockoff, air pump delete, off road y-pipe, and several other things)

When somebody posts a file on the internet (their tune out of their car) and you download it to your computer so that you can put it in your car.......it has a memory of their VIN.....you have to change that with your programmer.

To have a M6 program for LS1Edit is not a problem: http://www.ls1edit.com/filelib

But how to change the VIN? I'v never find this function in Edit. And if you retype it it will save the file with the original VIN.
Please explain this is the only thing that is holding me to do the trans swap

Thanks - Stefano

I had a shop re-flash mine with HP tuners for $50.

With LS1edit, I know you can do it, but not sure of the method. I heard if you have the same year flash with some certain part of the VIN # being the same you can do it.

on hptuners, you can use another file but it must be from a car that is the same year. I tried using a 2002 file on my 2001 car and it wouldn't work. Tried a 2001 file and it works perfectly
