Title: New to ECU flashing. B5 A4 4.2 swap in progress, could use some advise! Post by: tinytim on June 28, 2013, 04:48:06 PM Hey guys. So I am in the process of swapping a 2001 AWN 40v 4.2 into a 1996 B5 A4. I have to retrofit the DBW setup as this is a DBW engine. All that stuff I am OK with. When it comes to the programming of the ECU, that's where I am lacking. I am no stranger to swaps and things of that nature, I have just never been in a position where some re-flashing is absolutely necessary to get the car up and running. I have read a lot about flashing and its one more thing Id like to be able to do myself. I have the "dumb" cables from my VCSD setup already. Here's where I need some guidance.
1. Immobilizer defeat 2. Flash to accept a 01a 5 speed trans 3. *maybe* some tuning if there is anything available for the 40v 4.2 I think that's it really. Where does one obtain the files to flash for the trans? Where would you obtain tuning flashes? Am I missing anything... is there more to it then flashing and programming the appropriate stuff for the IMMO defeat? Tim Title: Re: New to ECU flashing.

Because there is no replacement for displacement! :P ..heard that somewhere lol Title: Re: New to ECU flashing. B5 A4 4.2 swap in progress, could use some advise! Post by: tinytim on June 29, 2013, 04:23:18 AM Why would you swap that in and not a 2.7t? Well that doesn't help answer my question in any way! I have already swapped a 2.7t... why do the same thing twice!? Not a lot of people do the 4.2 swap, so I want something different. Please don't turn this into a '2.7t vs 4.2' thread...

Post by: ddillenger on June 29, 2013, 08:29:47 AM Read the "understanding/retrofitting immobilizer" sticky, and the s4 tuning wiki. I can provide you with an s6 manual file (available in the tuned files, 4D0907559E) with the proper injector and MAF data for the A6. Do some reading, if you have any questions after that we'll be happy to help.

Is it worth getting a bench flashing setup too? Title: Re: New to ECU flashing. B5 A4 4.2 swap in progress, could use some advise! Post by: ddillenger on June 29, 2013, 12:15:16 PM Excellent.

If you have an issue (lose power, fail a flash, get disconnected) with a flash, you may need to recover with bootmode. In that case, a bench flashing setup is much easier to deal with than trying to do it in the car. Title: Re: New to ECU flashing. B5 A4 4.2 swap in progress, could use some advise!

In that case, a bench flashing setup is much easier to deal with than trying to do it in the car. After reading through the wiki on bench flashing and seeing that its a minimal cost for the supplies, I'm going to get myself set up for bench flashing too. I plan to flash my 2.7t at some point also. The 4.2 will be practice. Kinda excited to give this a go. Ive been wrenching on cars for 15+ years... its about time to dive into what I was always afraid of! Title: Re: New to ECU flashing. B5 A4 4.2 swap in progress, could use some advise! Post by: tinytim on June 30, 2013, 10:22:26 AM Last night I ordered all the supplies for bench flashing. Ended up getting:
-ebay obd/409 cable -male to female obd cable to use for the male end connector (I plan to splice a harnesses together, I dont want to mess with alligator clips every time) -audi ecu pigtail -450w pc 12v supply (already had this so I figured id just use it) -Asus x501a laptop (I wanted something dedicated for flashing/vag com) Also got a me7 ecu for the 4.2. Title: Re: New to ECU flashing. B5 A4 4.2 swap in progress, could use some advise! Post by: ddillenger on June 30, 2013, 10:32:35 AM Make sure your ecu is ME7.1.1, not ME7.1, as the euro files that work well aren't 7.1 compatible.
Title: Re: New to ECU flashing. B5 A4 4.2 swap in progress, could use some advise! Post by: tinytim on June 30, 2013, 10:35:47 AM I made sure to get a ME7.1.1... I did my homework!
Title: Re: New to ECU flashing. B5 A4 4.2 swap in progress, could use some advise! Post by: Carsinc on June 30, 2013, 09:00:39 PM I'm going to recommend buying a Galetto(not sure of spelling) cable.

Based on what? Title: Re: New to ECU flashing. B5 A4 4.2 swap in progress, could use some advise! Post by: tinytim on July 01, 2013, 07:04:38 AM I'm going to recommend buying a Galetto(not sure of spelling) cable. If I plan to bench flash, what would I need the cable for, if I need to bootflash when the ECU is in the car... as a backup basically? Title: Re: New to ECU flashing. B5 A4 4.2 swap in progress, could use some advise! Post by: Carsinc on July 01, 2013, 11:22:30 AM Because I like having choices and if something goes wrong, boot mode with galetto?? seems to work great for me.
I was bench flashing a ECU with a big name tuners software last week when the power went out here. There was a storm. It saved my ass I was able to load some file to get the ecu talking again. The big name tuner would not continue the flash. I'm sure some others would have worked but for like 20 bucks of ebay. Its worth it to me. Title: Re: New to ECU flashing. B5 A4 4.2 swap in progress, could use some advise! Post by: ddillenger on July 01, 2013, 11:33:32 AM IMO, (cloned) Galletto is the worst software ever. ESPECIALLY as it comes from ebay.
The MPPS leads are better, do bootmode and regular flashing and more. If you are stuck using galletto, just buy a generic ft232r cable and modify the galletto software to use it. Best of both worlds.

Post by: tinytim on July 03, 2013, 02:37:04 PM Here's the link to my build thread if anyone is interested, post #51 is where the real work starts. Good info contributed from some members in pre-work posts. Useful 4.2 swap info:

Waiting on one more cable. Title: Re: New to ECU flashing. B5 A4 4.2 swap in progress, could use some advise! Post by: tinytim on July 09, 2013, 07:00:26 PM Bench flashing set up done!

Any step-by-step guides out there? End goal: IMMO defeat Manual trans No egr No rear o2 No evap Any tuning flash, if its available. Will be running 2.5" manifold back exhaust, high flow cats. Title: Re: New to ECU flashing. B5 A4 4.2 swap in progress, could use some advise! Post by: Carsinc on July 09, 2013, 08:18:37 PM Immo defeat is the easiest on this list atleast in my opinion. Just go look at the cluster part of this forum.
